7 Operating Modes

The detector provides for «Registration» and «Test» modes.

7.1 «Registration» mode is intended for registering the

detector in the wireless network in which it supposed to
operate (see p.8.3).

7.2 «Test» mode is intended for testing electronic and

optical circuits of the detector.
The mode is activated upon a command from the control panel
or LT. Within 5 seconds after the command receipt, the
detector should issue «Test fire» notification (in case of
detector normal operation) or «Detector failure» or «Power
failure» notifications (in case of corresponding failures).

8 Pre-Starting Procedure

8.1 After transportation in conditions differing from those of

operation, keep the detector unpacked for 4 hours in the
expected operating conditions.

8.2 Running Detector. Replacing Batteries

WARNING! Lithium-thionyl-chloride batteries have an effect of

«passivation» to provide the possibility of long-term storage. To
provide battery normal operation after long-term storage, hold
an «activation» procedure.

Step-1

Turn the detector’s electronic unit
counter-clockwise. Remove the
electronic unit from the detector
base.

Step-2

When using one battery to switch the detector ON, insert
the Primary battery.
Note – When using two batteries, it is recommended to
insert the Secondary battery first, and then the Primary
battery. The Secondary battery can be inserted up to 1
minute after inserting the Primary battery.
To replace the battery, remove the old one, and after at
least 30 seconds insert the new one.
The red LED lights up for 1 to 40 seconds – the battery
activation and checking period.
If after 40 seconds the red LED flashes triply every 25
seconds, re-activate the battery by removing it, and after at
least 30 seconds reinserting it.

Warning! If two batteries have been inserted, replace
both batteries.
