Designed to complement the range of Electro Detectors Zerio Radio Fire Alarm equipment, the EDA-A2050 electronic actuator / interface is powered entirely by internal batteries, controlled and monitored by radio.
In normal operation the actuator continuously listens via its built in radio receiver to any instruction emanating from its controlling panel. Once operating it continues to listen for further instructions to switch its contacts.
To ensure that the integrity of the communication link is maintained, frequent transmissions are made by the actuator / interface to the control panel so that in the unlikely event of the radio signal failing to reach the panel a fault is reported.
