Fire Command Center and Fire Annunciator
Description
Application
The D1256 can be mounted in secure areas for use as both a
system controller and annunciator.
Radionics’ D1256 Fire Command Center and D1257 Fire
Alarm Annunciator are four-wire serial devices used with the
Radionics’ D9124 Addressable 24 VDC Fire Alarm Control/
Communicator and the D9112, D9412, D7212 and D7412
Control/Communicators. One D1256 is included with the
D9124 panel, which can be accessed through the slide door
on the front of the enclosure.
The D1257 Remote Fire Annunciator is typically installed in
building entrances and areas with unrestricted access. Near
exterior doors in hotel or business lobbies are ideal locations.
This allows a responding agency, or persons evacuating the
building to quickly identify the type and location of the emergency
from outside the building without being in danger.
Both annunciators provide English text displays of system
events with highly visible blue vacuum fluorescent displays. A
built-in sounder alerts building personnel to system alarms
and troubles and guides responding agencies to the
annunciator location.
Both devices have a built-in sounder that allows them to be
installed in locations not in general view. Audible tones alert
personnel to fire system events and assist fire fighters in
locating the annunciator.
Both units are molded in durable red plastic and have low
profile enclosures. The wording “Fire Alarm Annunciator” is
clearly printed on the faceplate of the D1257. This allows
inspectors, service technicians and responding fire agencies
to identify the annunciator.
Installation
The D1256 and D1257 system annunciators connect to the
fire control/communicator through standard four-wire cable.
Shielded cable may sometimes be required where excessive
EMI is a problem.
The D1256 Fire Command Center is a full-function system
controller and annunciator. Four special one-touch function
keys provide user-friendly control over the system. The function
keys allow the user to silence the audible alarm output, silence
the trouble sounder, reset the annunciator display and reset
system detectors. Four additional navigational keys allow
access to other programmed system functions.
The field wiring connects to a four-wire harness supplied with
the unit. This harness plugs into a four-pin connector on the
circuit board through the back of the D1256 or D1257. Each
unit has three mounting holes in the base that allow secure,
correct positioning during installation.
The D1257 Fire Alarm Annunciator provides remote
annunciation capabilities without system control. Similar in
appearance to a D1256 Fire Command Center, yet the D1257
Fire Alarm Annunciator lacks function keys. This makes system
control functions inaccessible to unauthorized persons. Thus,
the D1257 can be placed in locations where the public may
have access to it. Two navigational keys allow the user to step
forward or backward through a list of system events.
Do not install the D1256 or D1257 in direct sunlight. This
damages the module components and makes the display
less visible.
Install, test and maintain these devices according to their
Installation Guides, NFPA 72, Local Codes and the Authority
Having Jurisdiction. Failure to follow these procedures may
result in failure of the devices to operate properly. Radionics is
not responsible for devices that are improperly installed, tested
and maintained.
