Astra-941
Laser Tester
Operating Manual
The operating manual describes the operating principle, opera-
tional, storage and maintenance conditions pertaining to laser
tester Astra-941 (hereinafter
“tester”) (Fig. 1).
1 Function
1.1
The tester is intended for remote operabil-
ity inspections of optic-electronic fire smoke
detectors Astra-421 (hereinafter Astra-421
detector).
1.2
The tester is powered by batteries (2 pcs.)
of
СR2430 type (voltage – 3.0 V).
Note
– It is possible to use more common
batteries of
СR2032 type. However, it will re-
duce the service life of such batteries.
1.3
The tester is protected against reversing
the polarity of the batteries.
