Description
1.0 Description
Use the Underwriters Laboratories, Inc. (UL) Listed
D185 Reverse Polarity Signaling Module (Figure 1)
with Bosch Security Systems, Inc. (Bosch) control
panels. You can also use the D185 with non-Bosch
compatible UL Listed control panels where
referenced in the associated installation
instructions.

2.0 Alarm, Trouble, and
Supervisory Conditions
If a single pair of telco lines connects to the D185, it
signals alarm and trouble conditions to the
monitoring station. If two pairs connect to the D185,
it also signals supervisory conditions to the
monitoring station.
3.0 Alarm and Trouble
Responses (One Pair of
Telco Lines)
The D185 provides a constant 10 mA of current to
the alarm telco outputs and 14 mA of current to the
supervisory output. This module responds to an
alarm (fire) input from the control panel by
reversing the alarm telco output polarity. The D185
responds to a trouble input from the control panel
by interrupting the current to the alarm telco
outputs.

Follow these instructions when installing
the D185. This 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.
Local regulations might prohibit the
transmission of trouble signals on the
alarm circuit. The trouble feature is not
suitable for remote station protected
premises service where the local
authority having jurisdiction (AHJ)
requires separate transmission circuits for
alarm, supervisory, and trouble signals.
System configuration is subject to the
local AHJ’s approval.
If the control panel sends an alarm during a trouble
signal, the D185 overrides the trouble telco output
and responds with an alarm telco output (reversed
polarity).
The D185 transmits system alarm status
information from the control panel to a monitoring
station. This module operates with either a 12 VDC
or 24 VDC supply. All circuits are power limited.
The three D185 input terminals accept alarm,
trouble, or supervisory input from the control panel.
It responds to the input by communicating these
conditions to a monitoring station. There is a builtin 20 sec (±5 sec) delay of alarm output.
Under normal conditions, the D185 sends a steady
current to a monitoring station. In an alarm or
supervisory condition, the D185 reverses the output
current polarity and signals a trouble condition by
interrupting the output voltage and current.

4.0 Supervisory Response
(Two Pairs of Telco
Lines)
If the supervisory telco outputs connect to a
monitoring station, the D185 responds to a
supervisory signal by reversing the polarity of the
supervisory telco outputs.
6.1
Removing Power from the FACP
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. Before making or removing any connections to
the FACP, remove the standby battery power.
2. Remove AC power from the system at the
dedicated 120 VAC breaker.

5.0 Alarm Test
The Alarm Test Switch (Item 1 in Figure 1 on page
2) disables module output during testing that
triggers a trouble output from the D185 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 2 in Figure 1).
Mounting the D185
The D185 mounts on a snap-track and installs in
the control panel enclosure. You can also mount
the D185 in a separate, adjacent enclosure
connected to the control panel by conduit or other
protection against wiring damage. The snap-track
is slotted and drilled for quick installation.
6.3
Connecting the D185
The D185 has 12 screw terminal connection points,
6 on the left side for input points and 6 on the right
side for output points (Figure 2).

6.0 Installation Standards
Install, test, and maintain the D185
according to these instructions, NFPA 72,
local codes, and the AHJ. Failure to
follow these instructions can result in
failure of the D185 to report an alarm
condition. Bosch is not responsible for
improperly installed, tested, or maintained
devices.
Install the D185 up to 20 ft (6 m) from the
control panel with a minimum of 22 AWG
(0.8 mm) wire. Ensure all wiring is in
conduit.
Install the D185 in a system by:
• Removing power from the control panel,
• Mounting the D185,
• Connecting the D185,
• Restoring power to the control panel, and
• Adjusting the amount of output current.

SUPV ZONE Terminal changes from an open
collector (high resistance) to sinking current

Wiring the D185 to a D7024 or
DS9400 Series Control Panel with
ROM Version 2.03A and Newer
The D185 can signal alarm, trouble, and
supervisory conditions. Figure 3 shows the D185
used to signal alarm and trouble conditions only.
Supervisory conditions can also be signaled using
a third relay and an additional leased line.
In the example shown in Figure 3, you
must program Relay 1 to operate on
alarm and Relay 2 to operate on
trouble. Program Input 4 as a
supervisory input point. Any alarm
causes an interruption in the voltage to
the monitoring station. Placing the
D185 in Test Mode causes a
supervisory trouble condition.
Connect input power only to the PWR
Terminals.
