The 1166 is powered by a 3V lithium CR2477 battery inserted into a sliding tray. When the battery gets low, a 

LOBAT message is sent to the panel. When the LOBAT message appears, replace the battery and perform a 

sensor reset by following the process below.

Caution: Properly dispose of used batteries. Do not recharge, disassemble, heat above 212°F (100°C), or 

incinerate. These conditions may lead to fire, explosion, and burns.
