Instructions for use / battery replacement
After inserting the battery and pulling out the insulation film, the mag-
netic contact enters working status.
The magnetic contact will check the voltage when powering on. If
the voltage is lower than 2,5 V, it will send low voltage signal (low batt)
to the alarm central within 10 seconds. Meanwhile it will send to the
alarm central every hour.
Replace a discharged battery immediately. Only use batteries of
type CR2450. When inserting the battery, please pay attention to the
correct polarity!
If you change the battery, it will send a recovery signal.
