Detector removal

Unlocked detector heads are disassembled by turning them to the left and removing them
from the base.
Locked detector heads are disassembled by inserting a screwdriver into the unlocking opening
(Y). At the first time removing the detector, push the screwdriver hard through the plastic to
get to the locking clip. Push the screwdriver upward and turn the detector to the left at the
same time.

Address setting

The versions for automatic and manual address setting have three rotary switches on the
bottom of the detector. Use the rotary switches to select automatic address setting or manual
address setting with or without auto-detection. The versions without rotaries are automatically
addressable only.
The following settings are possible:
Rotary switch setting
Move the rotary switches to the required position using a slotted-head screwdriver.
Automatic address allocation
If addresses are automatically allocated by a fire panel with LSN improved version technology,
all detectors must have the address "0 0 0" (delivery status).
