The EA500B Transponder is a device controller for up to 64 devices, any combination of receivers and alert units. Its primary function is to monitor the receivers and alert units and report conditions and events to the central console over wire or ProxLink radios. It also provides power to certain devices.

Functions

Function During Alarm

When a receiver or alert unit detects an alarm, it goes

•

into an Off‑Normal state. To quickly locate any devices which might be in the Off‑Normal State, the transponder issues global commands that are interpreted simultaneously by all of its devices approximately ten times per second. The transponder sends commands to specific devices

•

to determine the nature of the Off‑Normal condition. During an alarm or test, the transponder sends commands to obtain the transmitter identification number, transmitter battery condition, and received signal strength. The information is then sent to the central console

•

either by wire or through ProxLink radios, where it graphically shows the identity and location of the subscriber (user) sending the alarm.

Configuration

The transponder identifies each receiver and alert unit by a multiplex address. The address is set during system installation using a multi-position switch on the receiver or alert unit circuit board. Transponders communicate on the data bus with individual multiplex devices by issuing commands, which contain the receiver or alert unit’s multiplex address.

Setup and Testing

Each transponder and the devices connected to it are set up and can be tested remotely from the central console. Also, each transponder reports any problems, such as low battery, immediately upon detecting them.

Installation/Configuration Notes

Installation

The transponder is for indoor use only. The transponder mounts in one of two different sized enclosures. Connect devices such as receivers, alert units, or combinations of both to the transponder using eight four‑wire multiplex buses, two wires for power and two wires for data. Each bus can support up to eight devices for a combined total of 64 devices. A Security Escort System supports up to 255 transponders and a total of 16320 devices.
