1 Purpose
1.1 The laser tester is intended for
launching of the registration process for
detectors (IR, FCP, SD, MC and AC) in
the wireless network, testing them
remotely, and searching for the best
operating data delivery route within the
network.
1.2 Power is supplied to the laser tester
from 2 built-in CR2430-type battery
cells of 3.0 V.
Note: The more common CR2032-type
battery cells may be used. In this case,
the battery cell lifetime is reduced.
1.3 The tester has protection against
battery cell polarity reversal.

4 Structure
Structurally the laser tester is designed as a key fob, consisting of
a cover (front side) and a base (Figure 2).
Figure 2
Mounted in the cover are buttons and a printed circuit board
with radio elements and battery cells. The base is fastened to
the cover by a screw.
Mounted on PCB is the LED for laser tester operability
supervision.
