Pager

All troubles with these checkboxes checked send a page to the service pager when the respective trouble becomes active.

Communications Failure

To continually assure that communications between the central console and each transponder are functioning properly, each transponder is required to send a message to the central console periodically. If there is no response from the transponder, the central console displays a Communications Failure warning on the central console and records the condition in the audit file.

If a transponder determines it lost communications with the central console, it assumes control of the outputs of the devices connected to it and transmits I’M OK messages until it is acknowledged by the central console.

If during this loss of communications, an alarm

transmission is received by one or more of the receivers attached to the transponder, the transponder activates any alert units attached to it as well as the horns and red LED’s on any of its receivers which detected the alarm transmission. Since the transponder does not have access to the Subscriber Database, it must assume that all transmitters are valid, so even unauthorized (not in the Subscriber Database) transmitters produce audible alarm indications (if the System is set for audible alarms in the Set Security Preferences Screen).

The central console also attempts to reestablish communications by continually requesting transmissions from the transponder and listening on the communications channel. When communications are restored with the central console, the transponder transmits any alarm and trouble conditions that occurred during the communications loss, and control of the horns, LED’s, strobes, and sirens reverts to the central console.

This approach to managing a communications loss assures that alarm events can not go undetected even if the central console is out of operation temporarily.

AC Loss

The transponder senses when it loses AC power and reports the condition to the central console. After a few seconds delay, the central console, displays a pop-up alert and records the condition in the audit file. See Section 3.3.10 Transponder Current Status Screen.

Low Battery

Periodically during normal operation, the transponder tests its battery. If the test fails, it immediately reports the condition to the central console. After a few seconds delay, the central console displays a pop-up alert and the condition is recorded in the audit file.
