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.
