BOSCH EA500 Transponder

Product Information

The EA500 Transponder is a Security Escort module that enables communication between the central console and multiple receivers and alert units within the protected area. In addition to its communication functions, the transponder also provides power to the receivers and includes drivers for a single strobe and siren.

Here are the specifications of the EA500 Transponder:

Enclosure (AE3)| Temperature Range| Power| Power Output| Driver Outputs| Battery Backup| Multiplex Buses| Communications Interface| Keyswitch Input Compatibility| Tamper Switch (option)
---|---|---|---|---|---|---|---|---|---
52.7 cm x 38.1 cm x 10.8 cm (20.75 in. x 15 in. x 4.25
in.)| N/A| 18.0 VAC, 50 VA maximum plug-in transformer for 110 V, 60
Hz| 9 VDC used for SE485 or Proxim radio power| Strobe: 500 mA solid state sink, terminal switches to ground in
an alarm condition. Siren: 500 mA solid state sink, terminal
switches to ground in an alarm condition.| 12 VDC lead acid battery| Eight multiplex drivers, each capable of driving eight
receivers or alert units for a combined total of 64 receivers and
alert units per transponder.| Selectable SE485 or RS-232| P/N: CTS1-70, Normally Closed

Product Usage Instructions

Mount the enclosure to the desired mounting surface.
Mount the circuit board to the enclosure. Refer to Figure 1 in the user manual for visual guidance.

Wire the transponder according to Figure 2 in the user manual. The wiring to the receivers and alert units can be done in the following ways:

Home-run (individual)
Daisy-chain (device to device)
A combination of both
T-tapping is also acceptable.

The recommended cable for wiring is a 4-conductor, 18 AWG (1.2 mm [0.05 in.]) fire rated cable. For wiring from SE485 to the transponders, you can use the following wiring methods:

Home-run (individual)
Daisy-chain (device to device)
A combination of both
T-tapping is also acceptable.

The recommended cable for this wiring is a 4-conductor, twisted pair, non- shielded, 22 AWG (0.8 mm [0.03 in.]) cable.

Setting the Address

Each transponder in the system must have its own address. Set the address on the transponder using the DIP switches located in the upper-right corner. Refer to Figure 3 in the user manual for visual guidance.

Overview

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.

terminal switches to ground in an alarm condition.

Battery Backup| 12 VDC lead acid battery
Multiplex Buses| Eight multiplex drivers, each capable of driving eight receivers or alert units for a combined total of 64 receivers and alert units per

transponder.

Communications Interface| Selectable SE485 or RS-232
Keyswitch Input| 47k EOL resistor, supervised loop
Compatibility| ROM version 4.00 or greater (the version shipped with this unit) is compatible with “–304” equipment (such as EA102A-304). Version

4.00 or greater is not compatible with non “–304” equipment.

ROM versions earlier than 4.00 are compatible with non “-304”

equipment.

Tamper Switch (option)| P/N: CTS1-70, Normally Closed

Mounting

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.

Mount the enclosure to the mounting surface.
Mount the circuit board to the enclosure. See Figure 1.
View to show retainer tabs. Insert board between tabs to secure.

Wiring

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.
