Monitoring and Testing
Refer to the characteristics of the devices related to the interface.
Cover-lid protection is triggered when the rear inside cover of the device is opened: in order to attain forced removal protection in the two installation solutions you must install a longer spring (included) on the tamper switch, so that it stays pressed down against the bottom of the 503 housing and/ or wall.
The device is a dual frequency radio transceiver and allows radio control of:
a) from 1 to 64 detectors and/ or Silentron remote controls. It receives the signals and directs them to the control panel through the bus;
b) from 1 or 16 RX Silentron transceivers for load control (any electric device that can be controlled with the relay).
c) an unlimited number of Silentron indoor/outdoor sirens and displayers.
