» Multi Zone Repeater Alarm Module : RAA

The RAA System is a range of Annunciator Panels comprising a fully self-contained Alarm System available in three cabinet sizes, 1 to 8 alarms/zones, 1 to 16 alarms/zones and 1 to 32 alarms/zones, and can be made to the specific number of zones required. All units are fitted with terminals for linking to the remote alarms, which can be No-Volt Relays or Switches. The RAA system as standard requires to monitor Normally Open contacts. (Monitoring of Normally Closed contacts is an optional extra and would require separate configuration).

When contacts within the alarm source close, the light on the RAA activates. RAA Units have three levels of indication for each zone; green LINE HEALTHY, red – LINE FAULT and flashing red ALARM DETECTED. The audible alarm is activated by any abnormal condition, ‘latches-on’, and is silenced by pressing the mute button. When the Mute Button is pressed the System will automatically reset, requiring no further operator input, but alarm lights remain on until the condition clears. An additional light indicates MAINS FAILURE, and a LAMP TEST Light and Test Button indicate the condition of indicator lights. RAA Units require a mains power supply and utilise a 5V signal to link to the alarm sources. The Link would be by a two core Leader Cable which can be supplied to length. The RAA can also monitor line continuity of the Leader Cable to the remote alarm source by fitting a Diode across the remote No-Volt Relay. If the line is cut, the RAA will raise a " Line Fault " Alarm.

RAA Units can be supplied with an optional Battery Backup Pack to enable the system to continue functioning for 10 hours under full alarm conditions during a mains power failure. The System is provided as standard with two ‘Common Alarm' no-volt changeover relays which operate on an alarm being detected by any zone. These can be linked to a further Aqualeak Repeater Panel, or be linked into a Building Management system, or can be used to shut power, or shut water supplies via matched solenoid valves, or switch on sump pumps/drainage systems etc. The RAA System can also be supplied with optional Individual Zone Signalling output relays which would provide appropriate zone alarms via individual no-volt changeover relays, and Mains Power fault signalling via a further no-volt changeover relay. All RA Units can be linked to our Automatic Telephone Dialling Units which can advise remote locations out-of-hours that an emergency has occurred.

RA modules are connected to the alarm being monitored by up to 50 metres of leader cable. This distance can be longer but please check with us first to ensure specifications are not exceeded.
