D1256 Fire Command Center 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 Radionics D1256 Fire Command Center and the D1257 Fire Alarm Annunciator are four-wire serial devices used with the Radionics D9124 Addressable 24VDC Fire Control/Communicator and the D9112 and D7212 Control/Communicators. One D1256 is included with the D9124 panel. It can be accessed through the slide door on the front of the enclosure.
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 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.
Similar in appearance to a D1256 Fire Command Center, 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. |
