The T-6247 is easy to install controller features auto, manual, and isolate modes, selectable via the key switch. When selected to the auto position the panel will respond to any signal received from the buildings Fire Indicator Board (FIB), this signal then activates the alert tone. If, after a pre-set time this condition has not been attended to, the panel will change to the evacuation mode. The evacuation tone will continue to sound until the panel has been reset. In the manual position any of the functions may be initiated from the front panel controls. This isolates the unit so that the alert, evacuation and bell tones will not function. Provisions have been made for BGM source to be played through the controller. BGM is automatically muted when any other function is operated. A microphone input has been included on the front panel. This can be used for either general or emergency paging. The voice over message can be recorded by setting the rear panel mic record switch to ON, the message can be any length from 1 to 20 seconds.
