EA500 Transponder
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.
•
Mount the enclosure to the mounting surface.
•
Mount the circuit board to the enclosure.
Wiring
Wire the transponder. See Figure 3.
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 OK. The recommended cable is 4-conductor, 18 AWG (1.2mm) fire rated.
Wiring from SE485 to Transponders can be Home-Run (individual), Daisy-Chain (from device to device), or a
combination of both. T-Tapping is OK. The recommended cable is 4-conductor, 22 AWG (0.8mm).
Set the Address
Every Transponder in the system must have its own address. Set the address on the transponder using the
dipswitches in the upper-right corner. See the Figure 2.
Figure 4 shows how to set the dip switches for each possible address.
