Alarm Receiver DECRYPTA
The twin line alarm receiver card DECRYPTA for PC and PC compatible computers is a MCDI product. It carries a five year limited
warranty.
Physical characteristics of DECRYPTA
SizeSizeSize
Receiver has all out dimensions:
15” (L) x 5.5” (W) x 2”(H)
38 cm (L) x 14 cm (W) x 5 cm (H)
Housing: Rugged aluminum chassis.
Baked black enamel finish or nickel plating finish
Buffer memory
Buffer holds up to 800 events in Native mode, 1000 in Ademco emulation Mode. Buffer is used when computer is absent.
Unit keeps printing during fail time if power is connected and maintained. When computer comes back on, buffer empties to
the computer. If more than 800 events (1000 Ademco mode) are received in the buffer during fail time, DECRYPTA writes
over the oldest event. Written records may be available on printer connected to parallel printer port.
Printer port
Connector port for IBM compatible parallel printer type DB25. One printer can be used for all DECRYPTA linked by cables
MRDC2 or MRDC3, instead of one printer per DECRYPTA unit. Events are also displayed on last DECRYPTA for all units.
Phone jackDouble Phone connector type RJ11 on Rev 4 and Rev 5 . Connect Green and Red only on each connector
Power connector
A twelve (12) volt power input connector is located at the back of DECRYPTA. A 3 foot wire is supplied. Connect red wire to
positive side and black wire to negative side of power source
Alert/WarningBuzzer
On board buzzer is available for alert warning when Computer is absent.
Enable if setup parameter Check printer is set to Yes.
Is activated (start buzzing) by event to be printed on DECRYPTA printer port.
Stop buzzing by pressing twice (2) ON-LINE printer key. Refer to printer connected to DECRYPTA parallel printer port. Will
resume buzzing if printer is left off-line.
CMOS Lithium battery
Receiver memory function support depends on CMOS battery. CMOS battery is located on receiver position BT1. Renata
Model CR2430 or equivalent. Minimum life expectancy 7 years to 10 years. Shelf life: 4 months.
Software tool COMIRQ
COMIRQ is a DOS software program shipped with all receivers. It is used to check signals sent to PC by DECRYPTA. This tool is
very useful to find free IRQ.
To check installation and find free IRQ, run COMIRQ followed by COM,IRQ parameters.
Example: COMIRQ 3,5 (Check if IRQ 5 is free for a DECRYPTA installed on COM3)
When COMIRQ is displayed, send a signal to DECRYPTA where same setup parameters have been given . Signal is displayed only
if COM and IRQ are free. If no signal is displayed, change IRQ in COMIRQ and in DECRYPTA setup. Try again until signal is
displayed indicating a free IRQ.
Press Space bar to display one signal a t a time. Press A to empty receiver buffer and enable ACK.

Installing DECRYPTA receiver
Power the DECRYPTA from any 12 volt source. Connect DECRYPTA to a computer serial port using the supplied null modem cable.
It is recommended to connect a printer to the DECRYPTA parallel port. This printer insures a full hard copy backup of all signals
received by DECRYPTA. If a printer is not connected, make sure supplied jumper is connected to printer port.
Configuring DECRYPTA receiver
DECRYPTA is configured using Setup software INITPLUS or internal configuration menus. Configuration in French, German, Spanish
and Portuguese is handled only by internal configuration menus.
DECRYPTA can be configured two ways:
1. Using DECRYPTA display and Menus. See P 8 to 11 of this document
2. Using INTIPLUS setup program. Connect DECRYPTA to PC. See Section above on How to install DECRYTYPA

(3x1,4x2) Define code to trigger Listen-In mode in 3x1 or 4x2 formats
Printer/Buzzer Yes = Check printer on DECRYPTA port No= Do not check for printer (default)
By default DECRYPTA does not verify printer status on parallel port but sends data to be printed as if a printer
was connected to this port.
(Yes) option tells the DECRYPTA receiver to verify and report on the status of the printer connected to the
DECRYPTA parallel port. The status verification applies to the DECRYPTA (lowest COM) in the computer if
more than one MCDI receiver is installed. A connector is needed to daisy chain multiple DECRYPTA receivers
to send all output to one printer only.
When Check printer option is enabled (Yes) and the computer is absent, each event being sent to printer triggers
a warning buzzer. This warning sound may be stopped by clicking twice the ON-LINE printer key. Buzzing
resumes if printer is left Off-line.
Do not set the "Yes" parameter if no printer is installed. Multiple error messages could be generated by taking
this action.

Listen-in, Two way voice
Listen-in function
Some alarm panels offer the option for the Central station operator to listen for sound in the premises where the alarm signal originates.
Alarm panels supporting “Listen-in” keep the telephone line open after having sent a signal, to allow sound monitoring. The telephone
line will be closed by the Central station subject to operator action or receiver setup.
Listen-in criteria
Receiver DECRYPTA is triggered into “Listen-in” mode for incoming events according to panel setup for specific formats.
SIA and Contact ID formats have specific codes for Listen-in. See Panel setup.
DTMF formats use the AEx signal where x can be 0 to F at the Installer’s choice.
3x1 and 4x2 formats have no standard codes for Listen-in. DECRYPTA allows self selection of Listen-in codes at Setup time.
Receiver action upon reception of “Listen-in” trigger
Upon reception of event in the Listen-in category, DECRYPTA receiver maintains the telephone line open for a period of up to 180
seconds or less then 180 seconds upon reception of any telephone tone from the keypad.
Operator control for “Listen-in”
Operator must be warned by Monitoring software of account “listen-in” capability. Operator has a maximum of 180 seconds from time
of alarm reception to telephone pickup. Failure to pickup telephone in this delays will cause line hang-up by DECRYPTA receiver.
Once the line is seized by Central station local telephone, the hang-up action of DECRYPTA will have no effect.
To close communication with alarm signal site in the first 180 seconds when DECRYPTA is in action, operator must press any key on
the telephone keypad before hanging up. The DECRYPTA will hang up telephone line before 180 seconds only upon reception of a tone
from telephone keypad.
To close communication with alarm signal site after 180 seconds of event reception, simply hang-up the telephone. This is because the
DECRYPTA is not in function anymore, its delay having expired.

1) The power required by the host and the total of all adapter cards installed within the host environment, together with any auxiliary
apparatus, shall not exceed the power specification of the host apparatus.
The power requirements for the DECRYPTA receiver are:
From External Battery (standby) 12V 1A
2) It is essential that, when other option cards are introduced which use or generate a hazardous voltage, the minimum creepages and
clearances specified in the table below are maintained. A hazardous voltage is one which exceeds 42.4V peak a.c. or 60V d.c. If you have
any doubt, seek advice from a competent engineer before installing other adapters into the host equipment.
3) The equipment must be installed such that with the exception of the connections to the host, clearance and creepage distances shown
in the table below are maintained between the card and any other assemblies which use or generate a voltage shown in the table below.
The larger distance shown in brackets applies where the local environment within the host is subject to conductive pollution or dry non-
conductive pollution which could become conductive due to condensation. Failure to maintain these minimum distances would invalidate
the approval.
4) The analogue telecommunications interface is intended to be connected to telecommunication network voltage (TNV) circuits which
may carry dangerous voltages. The telephone cord(s) must be disconnected from the telecommunications system until the card has been
installed within a host which provides the necessary protection of the operator. If it is subsequently desired to open the host equipment for
any reason, the telephone cord(s) must be disconnected prior to effecting access to any internal parts which may carry
telecommunication network voltages.
Table:
Clearance (mm) Creepage (mm) Voltage Used or Generated by
XYHost or Other Cards
2.0 2.4 (3.8) Up To 50 Vrms or Vdc
2.6 3.0 (4.8) Up To 125 Vrms or Vdc
4.0 5.0 (8.0) Up To 250 Vrms or Vdc
4.0 6.4 (10.0) Up To 300 Vrms or Vdc
For a host or other expansion card fitted in the host, using or generating voltages
greater than 300V (rms or dc), advice from a competent telecommunication
safety engineer must be obtained before installation or relevant equipment
Above 300 Vrms or Vdc
