General

The EA500 transponder is the Security Escort module that provides communications between
the Central Console and the many receivers and alert units throughout the protected area. In
addition to its communications functions, it also supplies power to the receivers. Each
transponder also includes drivers for a single strobe and siren.

Mounting

Normally, the enclosures are mounted first and all the wiring run, then the electronics are
mounted, wired, and tested.
The enclosures come with their own mounting hardware (H500 Hardware Kit) for mounting
the enclosure to a wall and mounting the circuit board to the enclosure.

Wiring

Wire the transponder. See wiring diagram on Set the address, page 36.
Wiring to receivers and alert units can be home-run (individual), daisy-chain (from device to
device), or a combination of both. T-tapping is okay. The recommended cable is 4-conductor,
18 AWG (1.2 mm) fire rated.
