1 Notices
These instructions cover the installation of the D192G Notification Appliance Circuit Module in
a fire system supervised by a fire alarm control panel (FACP) or a combination Burglary/Fire
control panel.
Install, test and maintain the module according to these instructions, NFPA codes, 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.
Before installing the module, become familiar with the Installation and Operation Guide for
the control panel you are using.
The module uses only polarized (DC) signaling devices. Not all signaling devices are polarized.
The signaling devices used with the module must:
– be polarized (DC) signaling devices.
– match the voltage rating of the alarm power supply.
– not exceed the current rating of the alarm power supply.
– not exceed 3A per module.
– total no more than 12 D192G modules per system.
!
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.

2 Description
This module is used for wiring connections to remote signaling devices. Wiring is supervised
for open, short, or grounded circuit faults.
You can connect up to 12 D192G modules to the same system on the control panels listed in
the table below. For the individual annunciation of an indicating bell circuit, connect the
modules to separate points.
The module powers notification appliances from the control panel power supply or from an
Underwriters Laboratories, Inc. (UL 864) Listed auxiliary 12VDC or 24VDC regulated/
power‑limited power supply for fire protective signaling units and commercial/residential
burglar units. This feature allows the system to support more signaling devices on longer wire
runs. It also allows the use of 12V or 24V notification appliances requiring the appropriate
power supply.

6en | Operation Notification Appliance Circuit Module
2020.05 | 04 | 4998122260 Installation manual Bosch Security Systems, Inc.
3 Operation
During normal operation, the NAC loop is supervised for opens, shorts, and ground faults. If
any of these conditions is detected, the control panel indicates a trouble condition at the
command center. Program the control panel to report the condition to the central station.
(See Programming, page 18 .)
When the control panel detects an alarm, the alarm output circuit triggers the module to
supply circuit power to the NAC devices.
When testing the alarm panel, the module uses a toggle switch to silence the fire alarm
indicating devices. When the toggle switch is in Silence Mode (off), the module indicates a
supervisory trouble condition to the control panel and the yellow SUPERVISION TROUBLE LED
lights.
The following table indicates possible causes for the various LED indicator patterns:
Indicator Possible cause
SUPERVISION TROUBLE LED (yellow) is on. – Output loop or 560Ω EOL resistor is
open or missing.
– Alarm switch is in SILENCE (OFF)
position.
SUPERVISION TROUBLE LED and ALARM LED
(red) are off.
– Normal operation with no alarm or
trouble.
– No power. Check for voltage across the
External Power In and Common
terminals. If the external voltage is not
connected, the control panel reports a
trouble condition locally and to the
central station (if connected).
– The wire to the Common terminal is
open or missing. If Common is not
connected, the control panel reports two
trouble conditions locally and to the
central station (if connected).
ALARM LED is on. There is an alarm. The LED follows the
operation of the output relay when the Alarm
switch is in the ON (NORMAL) position.
SUPERVISION TROUBLE and ALARM LEDs are
on.
If the Alarm switch is in the SILENCE (OFF)
position and the module is in alarm, both the
SUPERVISION TROUBLE and ALARM LEDs
light.

4 Installation
To connect without an external power supply:
– Mount the module(s) inside the control panel enclosure. You can use any mounting
position.
– Use a UL Listed tamper switch on the enclosure in a commercial burglary application.
– If installing the module in a separate UL Listed enclosure, install the enclosure according
to the manufacturer’s instructions.
– For UL fire applications, mount the module within 20ft (6m) of the control panel
enclosure with the wiring in conduit between the two.
– For multiple modules, you can connect up to twelve modules to the same supervision
point. The point must use a 1kΩ end-of-line (EOL) resistor.
– Install the 560Ω, 2W EOL resistor beyond the last notification device on each NAC loop.
This resistor is included with the module.
– For a supervised point, install a 1kΩ EOL resistor across the COM and SUPV ZONE
terminals on the last D192G module.

5 Wiring
Notice!
To ensure system supervision, do not use looped wire under the terminals. Break the run to
provide supervision of the connections.
Power supplied by the panel
The NAC loops are limited in that:
– Maximum draw for each signaling device circuit is limited by the control panel power
supply.
– No more than 12 D192G modules per system.
Power supplied by a remote power supply
The auxiliary power supply must be a UL864 Listed auxiliary 12VDC or 24VDC regulated,
power-limited power supply for fire protective signaling units and commercial or residential
burglary units. Install the auxiliary supply according to the manufacturer’s instructions.
Install the control panel and an external power supply in the same room no more than 20ft
(6m) apart. The interconnecting wiring between the control panel and power supply must be
in conduit.
The power source for both the power supply and control panel must be from the same
dedicated AC branch circuit.
The NAC loops are limited in that:
– Maximum alarm output equals the power supply rating.
– Maximum draw is 3A for each annunciating device.
– No more than 12 D192G modules per system.
