Alarm Bars may be equipped with lights and horn to provide visual and audible indications of alarm conditions. Models are available for both ordinary and Division 2 hazardous locations. A Quick Connect cabling option allows easy connection to either the WaveLink Receiver (WLR) or the WaveNet Relayer (WNR). Alarm bars with the Quick Connect option may also be "daisy chained" to provide annunciation at multiple locations from the same alarm relays.
