1 Notices
These instructions cover the installation of the D132A Smoke Detector Reversing Relay
Module in a household fire system supervised by a fire alarm control panel (FACP) or a
combination Burglary/Fire control panel.
Before installing the module, become familiar with the Installation and Operation Guide for the
control panel you are using.
Install, test and maintain the module according to these instructions, NFPA 72, local codes,
and the authority having jurisdiction (AHJ). Failure to follow these instructions can result in
failure of a detector to initiate an alarm event. Bosch Security Systems, Inc. is not responsible
for improperly installed, tested or maintained devices.
!
Warning!
Follow these instructions to avoid personal injury and damage to equipment.
NFPA72 requires that you perform a complete system wide functional test following any
modifications, repair, upgrades or adjustments made to the system’s components, hardware,
wiring, programming and software/firmware.

2 Description
This module allows compatible control panels (see the table below) to sound all smoke
detectors connected to point1 or zone1 when a single smoke detector on the loop goes into
alarm. To restore the smoke detectors to normal, reset the smoke detectors.
The following table lists control panels compatible with the D132A:

Notice!
To ensure system supervision, do not use looped wire under the terminals. Break the run to
provide supervision of the connections.
An external 12VDC or 24VDC power supply listed for fire signaling units and commercial or
residential burglary units can be used.
The external power supply must be UL1481 or UL864 Listed, regulated, and power‑limited.
Install the control panel and external power supply in the same room no more than 20ft (6m)
apart. The interconnecting wires between the control panel and external power supply must
be in conduit.
The power source for both the auxiliary power supply and the control panel must be from the
same dedicated AC branch circuit.
