These instructions cover the installation of the D185 Reverse Polarity Signaling Module in a
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.
NFPA 72 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.

Description
The D185 Reverse Polarity Signaling Module connects a control panel with either a single set
or a pair of leased telephone company (telco) lines in NFPA 72 remote station applications.
The module’s three input terminals accept alarm, trouble, or supervisory input from the
control panel, and the module transmits this information to a monitoring station after a built-in
20±5 sec) delay. This module operates with either a 12 VDC or 24 VDC supply. All circuits are
power limited.
The module can be used with the Bosch Security Systems, Inc. control panels indicated in the
following table. You can also use the module with non-Bosch, UL Listed control panels where
it is referenced as compatible in the control panel's installation instructions.

Operation
Under normal conditions, the module sends a steady 10 mA of current to the alarm telco
outputs and 14 mA of current to the supervisory output which connects to a monitoring
station. In an alarm or supervisory condition, the module reverses the output current polarity
and signals a trouble condition by interrupting the output voltage and current.

Table 3.1: Input and output states
3.1
Alarm and trouble responses (alarm output telco lines)
The module responds to an alarm input from the control panel by reversing the alarm telco
output polarity. The module responds to a trouble input from the control panel by interrupting
the current to the alarm telco outputs
If the control panel sends an alarm during a trouble signal, the module overrides the trouble
telco output and responds with an alarm telco output (reversed polarity).
3.2
Supervisory response (supervisory output telco lines)
The module responds to a supervisory signal input by reversing the polarity of the supervisory
telco outputs. A second set of telco lines must be connected.
3.3
Alarm test
The Alarm Test Switch (Item 18 in Figure 1 on page 2) disables module output during testing
that triggers a trouble output from the module during testing. Generally, this switch is off but
during an Alarm Test, you must move the switch to the ON position. Turning on the Alarm Test
Switch lights the Alarm Test LED (Item 17 in Figure 1).

Installation
Notice!
Install the module within 20 ft (6 m) of the control panel with a minimum of 22 AWG
(0.34 mm2) wire. Ensure all wiring is in conduit.
Install the D185 in a system by:

Danger!
Inform the operator and the local AHJ before installing this module in an existing system.
Disconnect all power to the control panel before installing this module.
1.
Removing power from the control panel
Before making or removing any connections to the FACP, remove the standby battery
power.
Remove AC power from the system at the dedicated 120 VAC breaker.
2.
Mounting the module
The module mounts on a snap-track and installs with a supplied screw in the control
panel enclosure.
3.
Connecting the module
The module has twelve screw terminal connection points, six on the left side for inputs
and six on the right side for outputs (see the D185 reverse polarity signaling module
figure in Description, page 3 and the Wiring, page 6 section).
Caution!
!
Connect input power only to the PWR Terminals.
4.
Restoring power to the control panel
Restore AC power to the system at the dedicated 120 VAC breaker.
Reconnect the standby battery power.
5.
Adjusting the amount of output current
To adjust the amount of output current required on the telco output, use a screwdriver to
rotate the alarm signal adjuster.
5
Wiring
An external 12 VDC or 24 VDC power supply listed for fire signaling units or 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 20 ft (6 m)
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.
