The model 5300 radio sounder is a battery operated sounder remotely activated and monitored by the system 5000 controller. Each unit has a unique address configured during manufacture and is individually addressable by the system controller. Each unit is
controlled individually or by zone, dependant on the system design.

The radio sounder is housed in an industry-standard, impact-resistant ABS moulding. The sounder has 2-way radio communication with the fire system controller using UHF
wavebands to receive command instructions and VHF for auto reporting.

The radio sounder model 5320 has a set of monitored contacts for the wiring of a remote call-point, thereby providing a very cost-effective component.

Designed and manufactured using the latest techniques and
surface mount technology ensures component count is kept
to a minimum, thereby maximising reliability.

The sounder is powered by a low-voltage dual supply Alkaline battery pack. The battery pack condition is continually monitored. The battery board has been tested to provide 5 years of normal site operations. The system indicates remaining battery capacity and a low battery condition is indicated to the controller as a fault leaving approximately 30 days for the battery pack to be changed.
