guidelines should be observed. The detector used with this base
must be tested and maintained regularly in accordance with NFPA
72 requirements. Canadian Installations must comply with the
Canadian Standard for installation for Fire Alarm System CAN/
ULC-S524 and the Canadian Electrical Code C22.1, Part 1.
NOTE: A COPY OF THIS GUIDE SHOULD BE LEFTWITH
THE OWNER/USER OF THIS EQUIPMENT.
INSTALLATION (CONVENTIONAL)
Connect zone circuit (IDC) to wiring terminals L1 and L2 on detec-
tor mounting base. (see Fig. 1). Provide regulated or unregulated
24VDC external power supply to sounder base terminals as shown
in Fig.1. Power supply must be UL Listed for Fire Protective Signal-
ing Systems. Please also refer to Fig. 6 and Fig. 7. for zone wiring.
INSTALLATION (ANALOG ADDRESSABLE)
Connect analog addressable loop (SLC) to wiring terminals L1 and
L2 on detector mounting base.(see Fig.3). Provide regulated or un-
regulated 24VDC external power supply to sounder base terminals
as shown in Fig.3. Power supply must be UL Listed for Fire Protec-
tive Signaling Systems. Please also refer to Fig. 8. for loop wiring.
PRODUCT DESCRIPTION
The Multi-Flex family of smoke detector sounder bases and syn-
chronization modules provide today’s most advanced functionality
and performance, delivering exible notication capabilities for
any installation.
The bases offer selectable steady or temporal pattern output and
selectable high or low volume levels. The three-pulse temporal
pattern is required by NFPA 72 for re alarm evacuation for com-
mercial and residential applications.
Available (SM) synchronization modules allow temporal pattern
sounder base circuits to be completely synchronized and installed
in almost limitless congurations, and also provide an on-board
latching test function.
The sounder base requires an external 24VDC power supply. In the
absence of a synchronization module,a means for polarity reversal
is required for test and general alarm functionality. The connec-
tions for the external power supply and the communication loop
are opto-isolated to prevent electrical interaction between them.
The 6-inch diameter sounder base mounts to 4-inch octagonal
and 4-inch square boxes. When mounting detectors on a ceiling,
install at least 4 inches from a wall. When mounting detctors on
a wall, install 4 to 12 inches from ceiling.
COMPATIBILITY
The Multi-Flex series is compatible withApollo analog addressable
(XP95A and Discovery Series) and conventional (Series 60A and
Series 65) smoke detectors,including heat,photoelectric and ion-
ization types. Please refer to the individual detector documentation
for more information.
The smoke detectors and bases are designed to operate in con-
junction with UL Listed FireAlarm Control Panels (FACP). Refer
to the FACP manual for guidance on maximum allowable devices
per loop. Contact Air Products and Controls or refer to your
FACP manual for approved compatibility.
The MB-SDRT-CV is fully compatible with the previous genera-
tion MB-SDR-S60 sounder base. Likewise, the MB-SDRT-AA is
also backwards compatible with the MB-SDR-XP95 sounder
base and MB-RLY-XP95 relay base models. The bases are also
compatible with the new MB-RLYT-CV and MB-RLYT-AA relay
bases, respectively.
BEFORE INSTALLING
Ensure familiarity with requirements for detector spacing, place-
ment,zoning,wiring and special applications. NFPA 72 and NEMA

Fig. 4 XPERT card addressing for Discovery and XP95
XPERT CARD PROGRAMMING
Analog addressable Discovery and XP95A bases employ a unique,
simple mechanism for hardware addressing (Fig. 2). The XPERT
Card provides a series of seven removable pips, which when
removed in proscribed patterns, corresponding to binary system
digits,and can represent numbers 1 through 126. Factory set and
labeled XPERT Cards are available.
NOTE: No buttons removed (address 0) or multiple like ad-
dresses on an SLC will cause an FACP Trouble/Fault condition.
NOTE: Remove the XPERT Card, select the desired address
and remove the pips indicated in black with a small screwdriver.
Replace the XPERT Card and twist the detector head into place
to complete programming (Fig. 4).
SOUNDER BASE PROGRAMMING
Program the desired volume and format of the sounder by con-
guring jumpers “JP1” and “JP2” on the sounder base PCB. JP1
controls the volume level, and is left ON for high level (85dB) or
taken OFF for low level (75dB). JP2 controls the format of the
sound, and is taken OFF for a continuous tone, or left ON for
temporal (code 3) pattern.
NOTE: If synchronization of the temporal pattern between two
or more sounder bases is required, an optional synchronization
module (SM) is required, as described below. When selecting the
temporal pattern with no synchronization,the sounders will “free
run” on an individual basis.
OPERATION
When a sounder base’s associated detctor goes into the alarm
state, the sounder will sound a continuous or temporal (code 3)
pattern,as programmed. This pattern will continue until the detec-
tor is succesfully reset to the normal standby state.

Fig. 5 Polarity reversal for testing or forced operation

© Air Products and Controls Inc. 2009 Page 3 INST APD0281 D090201
TESTING AND FORCED OPERATION
A group of sounder bases may be tested or force activated by
reversing the polarity of the 24VDC external supply. (Fig. 5). This
causes the sounder to activate. It is not necessary to have the
detctor head installed or in alarm for this operation. Note that
when doing a forced (or test) alarm operation, the sounder(s)
will continue to sound until the poalrity is returned to normal or
power is restored.
NOTE: All wiring must be installed in compliance with the
national electric code and the local codes having jurisdiction. Wires
must not be of such size or length which would cause the base to
operate outside of its published specications. The conductors
used to connect smoke detectors to re alarm control panels and
acccessory devices should be color coded to reduce the liklihood
of wiring errors. Improper connecitons can prevent a system from
responding properly in the event of a re.
For signal wiring (the wiring between interconnected detectors or
modules),it is recommended that the wire size be no smaller than
18 gauge (1.0 square mm),despite the terminals having capability to
accept smaller gauge wires. Wire sizes up to 12 gauge (2.5 square
mm) may be used with the base and modules. For best system
performance, the power (24VDC +/-) wires and the communica-
tion circuit should be twisted pair or shielded cable installed in
separate grounded conduit to protect the communication loop
from electrical interference.
Make wire connections by stripping about ⅜” of insulation from
the end of the wire. Then, slide the bare end of the wire under
the clamping plate, and tighten the clamping plate screw.
The zone wiring of the detector base should be veried before
the detector head is installed. Check the wiring for continuity
and polarity in the base.
NOTE: DO NOT USE LOOPED WIRE CONNECTIONS.
BREAK WIRE UNDER ALL TERMINALS TO ENSURE CIRCUIT
SUPERVISION.
NOTE:NE PAS UTILISER EN BOUCLE FIL FIL CONNECTIONS.

SYNCHRONIZATION MODULE
PRODUCT DESCRIPTION
The Multi-Flex (SM) synchronization module is designed to work
with the Multi-Flex family of conventional and analog addressable
sounder bases to provide the following:
1) A means of synchronizing the temporal (code 3) sound pattern be-
tween a number of bases in a common area (a group).
2) A means of testing or force activating the group of bases both from
the synchronization module (via the onboard test switch) and remotely
via the FACP.
3) A means of powering a group of bases (≤2A @ 24VDC nominal).
4) A means of silencing a group of bases from the FACP,with subsequent
alarm capability.
5) A means of triggering and silence agging connected secondary pro-
grammed SM synchronization modules and their associated sub-groups
of bases from a SM synchronization module.
The module is also compatible with the fully listed and approved
relay products from Air Products and Controls as shown in the
wiring diagrams to provide a fully code-compliant,supervised sub-
system. Each synchronization module can accomodate a circuit of
up to 61 sounder bases.
The Multi-Flex synchronization module is also designed to work
with the Multi-Flex analog addressable and conventional relay
bases, MB-RLYT-AA and MB-RLYT-CV, respectively. Please note
that when using these relay bases:
1) Synchronization is not a concern, as no pulsed pattern is provided
by the relays.
2) A test or forced (general alarm) operation will activate all connected
relay bases.
3) A silence operation will not effect the relays’ “ON” status.
When using the Multi-Flex synchronization module with the previ-
ous generation MB-SDR-S60, MB-SDR-XP95 and MB-RLY-XP95
sounder and relay bases, certain design limitations of the older
designs will not allow for:
1) temporal pattern synchronization on the older bases, as they are
continuous tone only devices.
2) silencing operations with sub-sequent alarm.
When replacing older model sounder bases where temporal
pattern is not required, simply set the Multi-Flex sounder base to
continuous pattern mode.

Input / Output Details
TROUBLE: Always FACP monitored and reported as trouble or supervisory in all program modes. Dry N.O.
contact held closed by the POWER 24VDC input being present and the internal module circuitry being fully
operational. Also supervises the presence of a SYNC IN signal when module is programmed in the “secondary”
or “sync only” modes. It is not used when the module is programmed in the “main” mode.
GENERAL ALARM: 24VDC steady or pulsed, silenceable or non, polarized FACP NAC Input. This input is used
only when the module is programmed in the “main” or “sync only” modes. When the connected NAC is in the
alarm state the module will provide a general alarm signal to all associated sounder/relay bases, causing them
to sound if a HORN ENABLE alarm input is also present.
HORN ENABLE: 24VDC steady or pulsed, silenceable polarized FACP NAC input. This input is used only when
the module is programmed in the “main” or “sync only” modes. When the connected NAC is in the alarm state
the module will be active and ready to accept a GENERAL ALARM input. The status of the connected NAC will
also be monitored for subsequently being silenced from the FACP and will provide that signal to all associated
sounder bases, causing them to silence. Subsequent alarms will resound as signalled from the FACP NAC con-
nected to this input.
SYNC IN: 24VDC/protocol feed input from associated module programmed in the “main”, “secondary” or “sync
only” mode. This input is always used when the module is programmed in the “secondary” or “sync only” modes.
It is not used when the module is programmed in the “main” mode.
SYNC OUT: 24VDC/protocol feed output from module in all modes. When the module is programmed in the
“main” or “sync only” modes, also provides distinct HORN ENABLE and GENERAL ALARM status information to all
associated sounder/relay bases and any modules programmed as “secondary”. Included line load stability resistor
must be installed.
POWER 24VDC: 24VDC power feed in, always required in all modes (to boost power available to bases due
to long wire runs and possibly the need to increase Db output). When the module is programmed in the “sync
only” mode this input could be from a shared power supply with the associated “main” programmed module.
When the module is programmed in the “secondary” mode this input will always be supplied from a new ad-
ditional power source since that is the only reason it is being installed.

MULTI-FLEX FAMILY
SOUNDER BASES AND
SYNCHRONIZATION MODULE
PRODUCT DESCRIPTION The Multi-Flex family of smoke detector sounder bases and synchronization modules provide today’s most advanced functionality and performance, delivering flexible notification capabilities for Apollo conventional and analog addressable systems. The bases offer selectable steady or temporal pattern output and selectable high or low volume levels. The three-pulse temporal pattern is required by NFPA 72 for fire alarm evacuation for commercial and residential applications.
Available synchronization modules (SM) allow temporal pattern sounder base circuits to be completely synchronized and installed in almost limitless configurations, and also provide an on- board latching test function. The sounder base requires an external 24VDC power supply. In the absence of a synchronization module, a means for polarity reversal is required for test and gerneral alarm functionality. The connections for the external power supply and the communication loop are opto-isolated to prevent electrical interaction between them.
