Lithium Battery - Honeywell GENT Nano panel-based Commissioning Instructions

Lithium battery

&
There are LETHAL VOLTAGES present on the Power supply assembly.
Therefore it is important when working on the MCB or PSU board to completely
power down the panel. The mains supply must be switched off and the battery
supply disconnected.
The 3V lithium battery suppled in the spares pack must be fitted to the Main control board (MCB).
The battery provides the power to retain the system configuration data in the event of panel power
failure or disconnection. See the 'Links' section for procedures on how to gain access to the Main
control board (MCB).
&
Always use the recommended replacement battery. As there is a risk of
an explosion if incorrect battery is used.
