1.0Overview
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, this transponder also supplies power to the receivers. Each transponder also includes drivers for a single strobe and siren.

3.0Mounting
Normally, the enclosures are mounted first and all wiring is run. Then the electronics are mounted, wired, and tested.
The enclosures include hardware for mounting the enclosure to a wall and mounting the circuit board to the enclosure.
1.Mount the enclosure to the mounting surface.
2.Mount the circuit board to the enclosure. See Figure 1.

4.0Wiring
Wire the transponder according to Figure 2.
The wiring to the receivers and alert units can be as home-run (individual), daisy-chain (device to device), or a combination of both. T-tapping is also acceptable. The recommended cable is 4-conductor, 18 AWG
(1.2 mm [0.05 in.]) fire rated.
Wiring from SE485 to the transponders can be home-run (individual), daisy-chain (device to device), or a combination of both. T-Tapping is also acceptable. The recommended cable is 4-conductor, twisted pair, non-shielded, 22 AWG (0.8 mm [0.03 in.]).
