Apollo 45681-331APO | Intelligent Sounder Visual Indicator Base | Red Flash

The Apollo 45681-331APO Intelligent Sounder Visual Indicator Base features a loop-powered sounder and visual indicator combined with a standard intelligent mounting base. It is used in order to signal a fire alarm in enclosed areas.

• Loop-powered sounder and visual indicator - needs no external power supply

• Operates at 17-28V dc and is polarity-sensitive

• Standard intelligent mounting base

• Used in order to signal a fire alarm in enclosed areas

• Moulded in polycarbonate

• Stainless steel contacts - accepts solid or stranded cables of up to 2.5mm

• The low volume range is useful in areas such as hospitals where a fire alert is initially intended to warn staff only

• Sounder is set to the high range for general use

• Synchronisation of tones ensures the integrity of the signaltones from different sounders do not merge into one signal that could be mistaken for a different tone

• Group addressing is a simple method of alerting an entire area or group of rooms without delay

• For systems requiring isolators at every point the built-in isolator saves installation time and cost

• The acoustic self-test means that the sounder listens to itself when it is switched on

• If no sound is detected a fault signal is transmitted when the sounder is polled

• The beacon self test is achieved by means of an LED monitoring circuit

• If the LEDs do not draw current when the sounder beacon base has been switched on a fault signal is transmitted when the device is next polled

• The Sounder Beacon Base responds to its own individual address set with a DIL switch
