Sounder Control Unit with Isolator
Part No. 55000-852
The Sounder Control Unit with Isolator is used to control the operation of a zone of externally powered sounders, visual indicators and VADs and to report their status to Apollo compatible control equipment.
The Sounder Control Unit with Isolator allows the devices to be operated continuously or be pulsed, 1 second on, 1 second off.
Devices may be operated individually or in groups and, whichever address mode has been applied, may be synchronised when in pulsed operation.
An opto-coupled input is provided to monitor the state of the external power supply.
The Sounder Control Unit with Isolator is fitted with a bi-directional short-circuit isolator and will be unaffected by loop short-circuits on either loop input or output. For further information on isolators please refer to datasheet PP2090, available on request.
Electrical Consideration
The unit is loop powered and operates at 17–28V DC. It requires a local power supply of 9–32V DC to power the external load, which may be up to 1A.
With reference to Figure 1, a polarising diode is required with each alarm device, as sounders are operated by voltage reversal, provided by a double-pole change-over relay. The sounder circuit is protected by a miniature (TR5) fuse rated at 1A.
XP95 AV CONTROL MODULE – ISOLATING
The XP95 AV Control Module is used to control and monitor the operation of a circuit of conventional sounders or bells.
EN 54-17 & EN 54-18 Certified
Allows sounders to be operated 1 second on, 1 second off
May be synchronised with loop sounders
Suitable for semi flush or surface mounting
XP95, Discovery compatible
