Battery Installation

The Lyric Gateway is equipped with an integral, replaceable, rechargeable battery pack rated at 7.2Vdc. In the
event of an AC power loss, the system is supported by the long life backup battery that is supervised for
connection and for low voltage conditions. If the battery is missing, or a low battery condition is detected, a
"low battery" message is displayed on the smart device and "Alert" will flash red on the Gateway. In addition, a
System Low Battery report is sent to the Central Station. In addition, the system will beep once every 45
seconds to audibly indicate a low battery condition (press any key to stop the beeping). Select the appropriate
battery pack, based on the installation's requirement, and install the battery pack. Follow the steps and refer to
the figure below to install and connect the battery.
