Chapter 1 – Introduction
Keltron's serial digital alarm communicator transmitter or SDACT and fire digital alarm communicator
transmitter or FDACT are unique solutions that remotely monitor fire alarm control panels (FACP’s), and
enable an appropriate and timely response from personnel at a life safety event monitoring center.
When activated by changes from the monitored FACP’s control circuit outputs, the SDACT and FDACT
transmit field-programmable event reports using the industry standard SIA format to any SIA-compatible
digital alarm communicator receiver (DACR) via the public switched telephone network (PSTN).
Additionally, the SDACT and FDACT can report events to two separate digital receivers located at two
different physical locations. This allows both local and off-site monitoring using a single communication
solution.
Keltron SDACT Model
The SDACT provides a remedy for FACP’s, and other systems, that cannot report point-specific, critical
alarm information to a local or off-site central station-style digital receiver through the PSTN.
The SDACT is a field-programmable, seven-zone, slave fire alarm digital communicator transmitter with
an RS232 serial port. The SDACT provides four supervised hardwired alarm zones plus three
unsupervised hardwired zones for external power source monitoring. The RS232 serial port is used for
field programming as well as for supplementary monitoring of serial data from the FACP.
The SDACT’s four alarm zones ensure that general event signals such as fire, trouble, water flow or
supervisory can be reliably transmitted. These signals are typically provided by the general alarm, general
trouble, etc., relay contact outputs of the FACP. In addition, the SDACT serial port monitors FACP serial
data, which is normally intended for a local printer or CRT display. That data includes point-specific
information such as detector type and address, and usually a broader range of event types. The SDACT
analyzes the data and converts it to the SIA format for transmission over the PSTN.
This unique serial interface is accomplished using FACP personality module software developed
exclusively by Keltron. The SDACT includes a personality software module that matches it to a specific
FACP. The specific personality module must be specified at the time the SDACT is ordered.
In order to report point-specific information from medium to large size FACP’s with a thousand or more
addressable detectors, SDACT uses all four of the zone number digits available in the SIA format.
However, some central station receivers or automation systems do not accept 4-digit zone numbers. To
accommodate these central stations, a firmware option is available to limit the zone numbers to 3-digits.
Instead, a range of account numbers is used, by adding what would be the 4th or leading zone digit to the
field programmed primary or secondary account number as required. Please see Appendix A for
additional detail. Currently the 3-digit option is factory configured only, and must be specified at time of
ordering.
For field-programming, the serial port must be disconnected from the FACP, and connected to a
WindowsTM PC running Keltron’s S/FDACT programmer utility.

Keltron FDACT Model
The FDACT is a field-programmable, seven-zone, slave, fire alarm digital communicator transmitter with
an RS232 port to facilitate programming quickly and easily from a WindowsTM PC running Keltron’s
S/FDACT programmer utility.
The FDACT provides four supervised hardwired alarm zones plus three unsupervised hardwired zones for
external power source monitoring. The FDACT’s four supervised alarm zones are used to monitor general
event signals such as fire, trouble, water flow or supervisory. These signals are typically provided by the
general alarm, general trouble, etc., relay contact outputs of the FACP.
Benefits
Using the widely available public switched telephone network (PSTN) the Keltron S/FDACT
family of products enables efficient reporting of life-safety events to a central monitoring location
or multiple locations.
The SDACT enhances FACP performance by facilitating point-specific fire alarm reporting
thereby enabling highly accurate responses through off-site annunciation.
The S/FDACT provides flexibility of operation through intuitive programmability. This ensures a
perfect match with project requirements and minimizes programming time. Default settings
minimize the setup time.
The S/FDACT provides general alarm and general trouble contact outputs. The alarm output
indicates serial port-derived events that are pending transmission and input zone activations. The
trouble output indicates telephone line faults, communicator faults, serial port faults as well as
input zone and power faults. These outputs may be monitored or simply provide local fault
indications.
Features
The Keltron SDACT contains a powerful microprocessor, an ASCII data-to-SIA converter and a
seven-zone digital communicator. This unique communicator combines seven hardwired zone
inputs and an RS232 serial port.
Primary alarm reporting is accomplished using the four EOL-resistor supervised zone inputs to
monitor alarm, trouble, water flow, and supervisory outputs from the FACP. The three
unsupervised zones may be used to monitor the AC power fail and no/low battery output contacts
from the external power supply, if available.
Zones 1 through 4 are typically used for standard alarm, trouble, water flow, and sprinkler
supervisory signal monitoring. Zones 5, 6 and 7 are additional inputs, typically used for reporting
the loss of AC and battery fail indications. All zones report using standard SIA event codes.
The RS232 serial communications port adds supplementary, detector-specific reporting of all
available information that enables accurate monitoring of event status, detector activation and
address, panel status, and fire progression. The RS232 port is personality-matched to the intended

3
data source through a software interface. When the receiving FACP can support it, this may
include communications supervision and interruption reporting.
Either a 2 Hour transmission delay or No delay for AC power failure conditions is jumper
selectable. (Refer to Programming features table on page 33)
Test code call-in cycles may be programmed for either 4 or 24 hours and transmit both normal and
off-normal condition test codes.
Telephone lines are supervised and faults are reported using standard SIA event codes.
A trouble report may also be sent to a separate telephone number as required by UL 864. In
addition, as required by UL 864, distinct audible sounds are provided for trouble and alarm, with
24-hour trouble resound.
Line seizure is provided for use with shared phone lines, as allowed by the local authority having
jurisdiction.
A manual test button is included.
A silence pushbutton deactivates the on-board audible signal.
A program pushbutton invokes the programming session.
A CPU reset button resides on board.
Local LED’s and audible devices clearly indicate S/FDACT status.
The Keltron S/FDACT provides contact outputs to indicate hardwired zone input activations and
general faults. The SDACT contact outputs also indicate serial port-derived events pending
transmission and serial port faults.
Event codes for the hardwired zone inputs may be programmed by the user.
The Keltron S/FDACT transmits signals in industry standard SIA format.
Included with the S/FDACT is a programming utility that requires only a PC with a serial port and
an appropriate cable.

FCC Requirements
Keltron’s SDACT and FDACT comply with Part 68 of the FCC rules and the requirements adopted by the
ACTA. Affixed to the dialer control board and inside the door of the optional enclosure is a label that
contains, along with other information, a product identifier in the format US:AAAEQ##TXXXX. If
requested, this number must be provided to the telephone company.
When ordering service from the local telephone company, the applicable certification jack Universal
Service Order Code (“USOC”) is RJ-31X. The associated Facility Interface Code (“FIC”) is 02LS2, and
the associated Service Order Code (“SOC”) is 9.0Y.
The plug and jack that connect the Keltron SDACT or FDACT to the premises wiring and telephone
network must comply with the applicable FCC Part 68 rules and requirements adopted by the ACTA.
Two code-compliant telephone cords with modular plugs are provided. These are designed to be
connected to a compatible modular jack that is also code-compliant. See installation instructions for
details.
The ringer equivalence number (REN) is used to determine the number of devices that may be connected
to a telephone line. Excessive RENs on a telephone line may cause those devices to fail to ring in
response to an incoming call. In most but not all areas, the sum of RENs should not exceed five (5.0). To
be certain of the number of devices that may be connected to a line, as determined by the total RENs,
contact the local telephone company. For products approved after July 23, 2001, the REN for this product
is part of the product identifier that has the format US:AAAEQ##TXXXX. The digits represented by ##
are the REN without a decimal point (e.g., 03 is a REN of 0.3). For earlier products, the REN is separately
shown on the label.
If the Keltron SDACT or FDACT compromises your telephone network, the telephone company will
notify you in advance that they may temporarily discontinue your service. If advance notice isn’t
practical, the telephone company will notify you as soon as possible. You will be advised of your right to
file a complaint with the FCC if you believe it is warranted.
Your telephone company may make changes in its facilities, equipment, operations or procedures that
could affect the operation of your Keltron SDACT or FDACT. Should this happen, the telephone
company will provide advance notice in order for you to make the necessary modifications to maintain
uninterrupted service.
Should you experience trouble with your Keltron SDACT or FDACT, you may contact Keltron Customer
Service at [phone] ext.2077 for repairs or warranty information. If the equipment is causing harm
to your telephone network, your telephone company may request that you disconnect the equipment until
the problem is resolved.
Please refer all service issues to a Keltron Certified alarm technician. The SDACT or FDACT cannot be
adjusted or repaired in the field.
The Keltron SDACT or FDACT may not be used on party lines. Connection to party line service is
subject to state tariffs. Contact your state public utility commission, public service commission or
corporation commission for information.

Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference when operated in a commercial environment. The
SDACT and FDACT generate, use and can radiate radio frequency energy and, if not installed and used
in accordance with this manual, they may cause harmful interference to radio communications. Operation
of these devices in a residential area is likely to cause harmful interference in which case the user will be
required at his/her own expense, to take whatever measures are required to correct the interference.
UL Requirements
UL Listed Signaling Device – UL 864 Central, Remote and Proprietary Protected Premise Unit Fire
Alarm System Service.
The four hardwired, Class B supervised alarm zones are the primary means of alarm signaling for
Keltron’s SDACT and FDACT dialers, while the serial data connection of the SDACT model provides
only supplementary information. Use of the Class B alarm zone inputs is required for UL Listed
installations remotely monitoring FACP’S via the Public Switched Telephone Network. To indicate the
supplementary and/or redundant nature of the serial data information at the receiving station, all serial
port events (SDACT only) are transmitted as ‘old’ events or SIA ‘O’ blocks.
The SDACT and FDACT are not suitable for the direct monitoring of sprinkler supervisory devices, PIV,
gate valves, tamper switches, etc., where ground fault detection is required by UL 864, 9th Edition, 2003.
Monitoring these signals using control circuits or relays from an FACP is permitted.

Chapter 2 – Operation
All Normal Operation
When the Keltron S/FDACT is powered, and the input zones and other monitored status conditions are
normal, only the green power on LED will be lit. All other LEDS will be dark. The audible will be silent.
The general alarm and general trouble relay contacts will be in their normal state.
Alarm Operation
Zone Alarms
For a status change into an alarm condition (short circuit) on a given alarm zone input:
The zone alarm LED for that alarm zone input illuminates.
The common alarm relay energizes and the alarm contact active LED illuminates.
The audible device sounds the pulsed alarm signal.
The programmed (or default) alarm event code is transferred to the SIA transmitter. (see dialing
operation)
The silence pushbutton may be used to silence the audible. Zone alarms are not latching, in that no user
intervention is required to enable subsequent status change reports, for example, if the zone restores to
normal.
Serial Port Events (SDACT only)
(For supplementary use only) When a complete FACP serial data message is received and recognized by
the personality software module as a message including a valid point status change:
The serial alarm LED illuminates.
The common alarm relay energizes and the alarm contact active LED illuminates.
The audible device sounds the pulsed alarm signal.
The corresponding event code (See appendix A) is transferred to the SIA transmitter (see dialing
operation) for transmission as an ‘old’ event using a SIA ‘O’ block.
If the corresponding event code represents an AC Power Failure message from the FACP, and if User
Jumper J8 is installed, then the transmission and all local indications are delayed for 2 hours. If a
corresponding AC Power Restore message is received from the FACP before the 2 hours elapses, the
pending AC Power Failure transmission and the Restore transmission are cancelled. If an AC Power
Restore message is received from the FACP after the 2 hour delay, i.e. after the AC Power Failure
message has been transmitted, then the Restore is transmitted without delay. (Refer to Programming
features table on page 33).
Note that the supplementary FACP serial port-derived events are not prioritized. All serial events are
equivalent regardless of event type as concerns the local indication of an alarm condition. Once the event
transmission is acknowledged by the receiving station DACR, the local alarm indications will cease, i.e.
the serial alarm LED will go out, the audible will be silenced, and the common alarm relay will return to
normal (assuming no other monitored conditions require the audible or common alarm relay to remain
active) .

10
Trouble Operation
Zone Troubles
For a status change into a trouble condition (open circuit) on a supervised alarm zone input (1-4):
The trouble LED for that alarm zone input illuminates.
The common trouble relay energizes and the trouble contact active LED illuminates.
The audible device sounds the steady trouble signal.
The programmed (or default) trouble event code is transferred to the SIA transmitter. (see dialing
operation)
For a status change into an off-normal condition on either the AC failure (zone 5), low battery (zone 6), or
no/missing battery (zone 7) zone inputs:
The power fault LED illuminates.
The common trouble relay energizes and the trouble contact active LED illuminates.
The audible device sounds the steady trouble signal.
The programmed (or default) power monitor event code is transferred to the SIA transmitter. (see
dialing operation)
If User Jumper J8 is installed, then an off-normal status change on the AC failure zone 5 will illuminate
the power fault LED, but the trouble relay, local audible, and the AC Power Failure transmission are
delayed for 2 hours. If zone 5 restores to normal before the 2 hours elapses, the pending AC Power
Failure transmission and the Restore transmission are cancelled. If zone 5 restores to normal after the 2
hour delay, i.e. after the AC Power Failure has been transmitted, then the Restore is transmitted without
delay. (Refer to Programming features table on page 33)
Note that the normal condition (normally open or normally closed) for zones 5, 6, and 7 is determined by
user jumpers 5, 6, and 7 respectively.
The silence pushbutton may be used to silence the audible. The audible will automatically resound for
zone troubles in 24 hours if the trouble condition is still present. Zone troubles are not latching, in that no
user intervention is required to enable subsequent status change reports if, for example, the zone restores
to normal.

11
Serial Port Trouble (SDACT only)
(For supplementary use only) Unless disabled by user jumper J4, the SDACT will continuously supervise
the integrity of the serial port connection to the FACP. When a serial port trouble condition is detected:
The serial trouble LED illuminates.
The common trouble relay energizes and the trouble contact active LED illuminates.
The audible device sounds the steady trouble signal.
The ET (expansion trouble) event code is transferred to the SIA transmitter. (see dialing operation)
Note that the yellow serial trouble LED indicates the SDACT serial port trouble ONLY. It does not
indicate the reception of a trouble signal from the monitored FACP. All signals from the monitored FACP
illuminate the red serial alarm LED to indicate an FACP signal is active and a transmission is pending.
The red serial alarm LED clears after the transmission is completed as explained above under Serial Port
Alarms.
The silence pushbutton may be used to silence the audible. The audible will automatically resound for
serial port trouble in 24 hours if the trouble condition is still present.
Telephone Line Trouble
While the telephone lines are not in use by the Keltron S/FDACT, the voltage of each line is continuously
monitored by the S/FDACT to supervise the integrity of the field wiring connections to the telephone
network. When a telephone line fault is detected:
The Telco fault LED for that line illuminates.
The common trouble relay energizes and the trouble contact active LED illuminates.
The audible device sounds the steady trouble signal.
The programmed (or default LT) line # trouble event code is transferred to the SIA transmitter.
(see dialing operation)
The silence pushbutton may be used to silence the audible. The audible will automatically resound for
telephone line trouble in 24 hours if the trouble condition is still present.
How it works:
The Keltron S/FDACT phone line supervision circuit does not measure loop current, and will not report a
line fault if the voltage is at or above a 1.8 VDC threshold. Due to circuit component variations, telephone
line faults may not be reported until the voltage drops below 1.4 VDC. The S/FDACT will always report
a fault at 0 VDC, the open circuit condition. It is expected that the minimum line voltage will be 2.75
VDC, and will occur when the lines are in use by parallel house phones or other devices upstream of the
S/FDACT.
The line voltages are checked every 30 seconds. Each line check takes two seconds, one second per line.
This 32-second cycle is repeated indefinitely. If a line fault condition is detected five times in a row, a line
fault is reported. Therefore, in the worst case, a fault is reported within 192 seconds (6 * 32), or 3 minutes
12 seconds after its occurrence.Any single line voltage reading above the threshold restarts the five-check
cycle and results in a line restore report - only if a line fault was reported previously.

12
Telephone Communication Trouble
If the Keltron S/FDACT is unable to complete a telephone call to a receiving station DACR, because of
failure to obtain a receiver handshake tone (2225 Hz), failure to receive a positive acknowledgement for
each data block (2025 Hz), or for any other reason, then a communication trouble condition has been
detected:
The Telco fault LED corresponding to the telephone number currently being used illuminates, i.e.
the line #1 LED for the primary telephone number and the line #2 LED for the secondary
telephone number.
The common trouble relay energizes and the trouble contact active LED illuminates.
The audible device sounds the steady trouble signal.
The programmed (or default YS) comm # trouble event code is transferred to the SIA transmitter,
where # is 1 for the primary telephone number, and 2 for the secondary telephone number.
(see dialing operation)
The silence pushbutton may be used to silence the audible. The audible will automatically resound for
telephone communication trouble in 24 hours if the trouble condition is still present.
Configuration Trouble
The Keltron S/FDACT stores user programmable settings in non-volatile EEPROM memory. The content
of this memory is checked for integrity at power-up or reset, and whenever a new user configuration is
programmed. If the configuration memory becomes corrupted, the S/FDACT cannot perform any dialer
functions, since the stored telephone numbers and account numbers may be invalid. When configuration
trouble is detected:
The eight Class B zone LEDS (4 Red alarm, 4 Yellow trouble) each illuminate. This is to indicate
the non-functional status of the dialer, since under normal conditions a zone’s alarm and trouble
LED will never be lit simultaneously.
The common trouble relay energizes and the trouble contact active LED illuminates.
The audible device sounds the steady trouble signal.
Note that no SIA transmission is initiated.
The silence pushbutton may be used to silence the audible. The audible will automatically resound for
configuration trouble in 24 hours if the trouble condition is still present. Configuration trouble can usually
be corrected by reprogramming a configuration with the S/FDACT programmer utility. See Chapter 4.

13
Restore to Normal Operation
Zone Restores
For a status change to a restore condition on a given alarm zone input:
If restoring from alarm:
The alarm LED for that alarm zone input goes out.
If no other monitored conditions require the common alarm relay to be active, it returns to its
normal state,and the alarm contact active LED goes out.
If no other monitored conditions require the audible to be active, the audible is silenced.
The programmed (or default) alarm restore event code is transferred to the SIA transmitter. (see
dialing operation)
If restoring from trouble:
The trouble LED for that alarm zone input goes out.
If no other monitored conditions require the common trouble relay to be active, it returns to its
normal state, and the trouble contact active LED goes out.
If no other monitored conditions require the audible to be active, the audible is silenced.
The programmed (or default) trouble restore event code is transferred to the SIA Transmitter. (see
dialing operation)
For a status change to the normal condition on the AC failure (zone 5), low battery (zone 6), or
no/missing battery (zone 7) power monitor zone inputs:
If all of the power monitor zones are normal, the power fault LED goes out.
If no other monitored conditions require the common trouble relay to be active, it returns to its
normal state, and the trouble contact active LED goes out.
If no other monitored conditions require the audible to be active, the audible is silenced.
The programmed (or default) power monitor restore event code is transferred to the SIA
transmitter. (see dialing operation)
Note that the normal condition (normally open or normally closed) for zones 5, 6, and 7 is determined by
user jumpers 5, 6, and 7 respectively.
Serial Port Restore (SDACT only)
(For supplementary use only) If a serial port trouble condition was previously detected, and either the
condition restores to normal or user jumper J4 is removed to disable serial port supervision:
The serial trouble LED goes out.
If no other monitored conditions require the common trouble relay to be active, it returns to its
normal state, and the trouble contact active LED goes out.
If no other monitored conditions require the audible to be active, the audible is silenced.
The ER (expansion restore) event code is transferred to the SIA transmitter. (see dialing operation)

14
Telephone Line Restore
If a telephone line fault trouble condition was previously detected, and the condition restores to normal:
The Telco fault LED for that line goes out.
If no other monitored conditions require the common trouble relay to be active, it returns to its
normal state, and the trouble contact active LED goes out.
If no other monitored conditions require the audible to be active, the audible is silenced.
The programmed (or default LR) line # restore event code is transferred to the SIA transmitter.
(see dialing operation)
Telephone Communication Restore
When the Keltron S/FDACT completes a call to a receiving station DACR, which was previously in
communication trouble:
The programmed (or default YK) comm # restore event code is transferred to the SIA transmitter,
where # is 1 for the primary telephone number, and 2 for the secondary telephone number.
(see dialing operation)
Daily Test Operation
If the Keltron S/FDACT is configured for 24 hour daily test interval (factory default), the daily test
transmission will be sent once per day at the programmed (or default midnight) daily test time. If the
S/FDACT is configured for 4 hour daily test interval, the test transmissions will be sent at the
programmed daily test time and every 4 hours thereafter.
Daily test transmissions will alternate the telephone line used for each test. Daily tests are only sent to the
primary receiving station (primary telephone number), unless the S/FDACT is unable to communicate
with the primary receiver.
If the S/FDACT is all normal, the programmed (or default RP) normal test event code will be transferred
to the SIA transmitter, otherwise the programmed (or default RY) off-normal test event code will be
transferred to the SIA transmitter.
