5207 Fire Alarm Control Communicator

The Silent Knight Model 5207 is an all-in-one fuseless local fire evacuation control panel and digital communicator designed for applications requiring manual fire alarm, automatic fire alarm and water flow for sprinkler system supervision. The basic unit offers fire alarm for one to eight zones, expandable to 16 with the optional 5210 expansion module. It is compatible with both two- and four-wire smoke detectors. Compact, easy to install and service, it delivers the features you'd expect to find in fire systems costing much more.

During normal operation, the 5207 constantly checks smoke and other sensing devices for fire conditions. It also conducts system checks to determine if any troubles, or system problems, exist. If the 5207 encounters a fire or trouble condition, it sends a report to a central monitoring station (if applicable), and, typically, sounds an audible/ visual warning in the local area.

The 5207's microprocessor constantly runs programs to check inputs and carry out other routine functions. If the program ever stops running, a watchdog circuit will detect it and reset microprocessors to resume normal operations.

The Model 5207 conducts an automatic self-test every 24 hours-at a time you select-and sends a report to the central station (if applicable).

Other features of the system include English-language remote annunciation simplifying "Step Programming" of custom options. Remote downloading of system configurations can eliminate the expense of sending out a service technician for reprogramming. System provides a built-in fire drill procedure. The exclusive Accu-Zone feature measures and displays zone voltages, so you can set up and test the system without separate testing equipment. Fuseless circuit board design eliminates one of the most likely causes for service calls.
