EDA Electronic Sounder

The unit is a self-contained powerful 104 dB electronic sounder incorporating both a radio transmitter and receiver requiring no external wiring. It contains two separate battery supplies, one acting as a backup to the other, with sufficient capacity for up to 5 years use under normal conditions. Tone adjustments are provided both by internal selections or by transmitted signals thereby enabling the sounder to provide several types of audio signal. Should a fault occur, the unit will be identified by its address and if available, its location. Specified as an option, the sounder can also provide a control signal to operate other equipment such as door release holders and remote signaling equipment which can be controlled independently of the sounder operation.
