u Compatible with Bosch GV4 control panels, Bosch

GV3 control panels, and GV2 control panels
(firmware version 7.04 and higher)

u Can be remotely installed in public access areas

The D1257RB Fire Annunciator is typically installed in
building entrances and areas with unrestricted access
because it lacks function keys. This SDI bus
compatible device works with the Bosch Security
Systems, Inc. GV4 control panels, GV3 control panels,
and GV2 control panels (firmware version 7.04 and
higher). Two navigational keys allow the user to step
forward or backward through a list of system events.
This allows a responding agency or persons evacuating
the building to quickly and safely identify the type and
location of the emergency.
The annunciator has a built-in sounder that allows it to
be installed out of sight. Audible tones alert personnel
to fire system events and assist fire fighters to locate
the annunciator.

Functions

show the status of the fire system. When several
events occur, each event is shown in order of priority
followed by the time of occurrence. In conjunction
with the 16‑character vacuum-fluorescent display
(VFD), four LEDs provide the following system status
indications:

Mounting Considerations

The annunciator is a low profile, surface-mounted unit
molded in durable red plastic with three mounting
holes in the base that allow secure, correct positioning
during installation. Protect the surface-mounted
annunciator by mounting it to a D56 or D56R Conduit
Back Box. For desktop applications, the annunciator
can be mounted to a D55 Desk Stand.

Notice

Do not install the annunciator in direct sunlight.
This damages the module components and makes
the display less visible. Do not mount in wet or
moist locations.

Wiring Considerations

The annunciator connects to the control panel for data
and power through a standard four-wire flying lead
cable. For field wiring use 0.8 mm (22 AWG) or

1.2 mm (18 AWG) wires. Resistance cannot exceed
25 Ω. The field wiring connects to a four-wire harness
supplied with the unit.

Notice

Use shielded cable where excessive
electromagnetic interference is a problem.
