Placing the Batteries
The NILF requires three 1.5V “C” (R14) alkaline batteries. The battery voltage is continually
monitored. A red LED will indicate low battery status (1 flash per minute) and tamper alarm
(continuous rapid flashing). Under normal circumstances the battery life is minimum one year.

Note: Optionally an NIRX transceiver module can be mounted on the LF location beacon -
NILF for actively monitoring the state of the NILF like tamper and low battery alarm
conditions.
