» 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.
