GSMHS Installation and Setup Guide

Backup Battery Connection

The included battery (K14139) is used for backup in the event of a system power loss.
 The battery can provide over 24 hours of system life in the event of a power failure.
 A programmable power loss message can alert the AlarmNet Control Center when system
power is lost (power loss messages are reported within 1-3 hours of actual loss).
 The module transmits a low-battery message (programmable) when the battery reaches
5.7V ±5%, indicating subsequent messages may not be transmitted.
 The system shuts down when the battery reaches 5.1V, and radio transmissions are no
longer possible.
 If system power is restored before the module shuts down, a power restore message is sent
within 1-3 hours after power is restored, and the battery is recharged using the GSMHS's
built-in battery charger. If system power is restored after the GSMHS has shut down, a
power-on reset condition exists, the module initializes itself and the battery will recharge.
Install the battery as follows, and refer to the Summary of Connections diagram at the end of
this document.
1. Place the battery inside the case back.
2. Snap the right side of the battery clip onto the inside of the case back and secure the
Do not plug the battery in until after you have powered-up the GSMHS.
