» Single Zone Repeater Alarm Module : RA+Plus

The RA single zone Remote Repeat Alarm  is a miniature annunciator designed as a stand-alone module powered from a local external mains or a 'low voltage' power supply. The RA is fitted with incoming terminals for linking to remote alarm sources and can accept an alarm signal from a 'clean N/V Relay' in the alarm source being monitored. 

When contacts within the alarm source close, the light on the RA activates. The light remains on all the time that the alarm source remains in alarm. The horn sounds and can be muted by pressing the Mute Button. 

RA Units are fully self re-setting on acknowledgement of the horn by pressing the mute button and require no further operator re-set. The horn automatically reactivates after any previous muting operation. 

The RA Module can be used to provide onward signalling when fitted with the optional 'No-Volt' output signalling relay (rated 240VAC 2amp) with 'Normally Open/Closed' change-over contacts (and can be provided with an optional relay facilities for 'Line Fault' and 'Power Failed', both rated 240VAC 2amp). This can be used to link to a secondary single zone alarm or to link to a BMS System. 

A local mains power supply is required to power the module, or a mains power cable link needs to be taken from the main alarm. The RA module can be manufactured for either 110 or 230V AC mains supply, or 12/24V AC supply. Power consumption is approximately 30mA on ‘run’ and 50mA in ‘alarm’ with relay energised. 

Normally a leader cable would connect the controller to the alarm source and should be connected to 'normally open' no-volt contact in the alarm source being monitored.
