Redback Emergency / Fire Evacuation Controller


Manufacturer: Redback

Product Information

This easy to operate fire & evacuation controller is designed around industry standard building emergency alert/evacuate requirements. When connected to a paging system amplifier, building occupants can be alerted and/or evacuated in the event of an emergency eg: fire, gas leak, bomb scare, earthquake. Auto or manual modes are selected by the front panel key switch (see below), which uses an industry standard 003 key. Alert & evac switches are fitted with safety covers to prevent accidental operation. 

Modes of Operation 
Auto: The alert tone is generated when a signal is received from the fire indicator board (FIB) or break glass detector. After a preset time the evacuate tone is sounded unless the alert tone is manually reset. The evacuation tone continues until manually reset. When selected to auto, front panel alert and evac controls are inoperative. Other controls such as paging, bell chime and BGM function normally. 

Manual: In the manual position any of the functions may be initiated from the controls on the front panel, i.e. Alert, Evac, or PA. 

Remote cancel function: Terminals are provided for the connection of a remote cancel switch. When activated with a closing set of contacts this will cancel any activated tone, regardless of the position of the master auto/manual/isolate key switch on the front panel. This is useful when the controller may not be readily accessible. 

Other functions: Provision has been made for a BGM source to be played through the controller. BGM is automatically muted when any other function is operated. A mic input is provided on the front panel. This can be used for either general or emergency paging. Paging overrides all other functions. A pre-announcement chime is available on the microphone input. This can be switched on or off internally. Also inbuilt, is a unique tone for signalling lunch breaks, start of class etc. This can be operated from the front panel or via rear contacts for remote activation ie. clock or remote switch.
