Changing the Batteries
When the batteries in the heat detector have reached a low charge, the device issues an
acoustic signal at regular intervals (refer to Low battery charge on page 12). Change
the batteries in the heat detector concerned within 30 days.
CAUTION
! Risk of property damage through using inap-
propriate batteries which are not approved by the manu-
facturer! The use of inappropriate batteries can cause loss
of function of the heat detector. Only use batteries ap-
proved by the manufacturer.
1
Remove the heat detector from its base (1).
2
Change the batteries (observe correct polarity!).
3
Install the heat detector in the base (1).
When the heat detector is connected to an alarm system, the alarm system base unit
also signals low battery power in the display.
4
On completing the work, initiate a function test.
