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.

SOMEBODY’S EYES!
6.1
After transportation in conditions differing from those of
operation, laser tester must be kept unpacked for 4 hours in
the expected operating conditions.
6.2
Focus the laser into a narrow beam:
- Hold and press any button.
- Move the end cap up and down to minimize the
diameter of the dot at the test distance.
- Release the button.

Test
procedure:
Table 2: Purpose of Buttons
Button
Purpose
Button 1
Launch test (send test alarm)
Button 2
Launch network optimization (search for
optimal data delivery route)
Button 3
Launch detector registration
Notes
1.
Button 1 is used for testing SD operability only; for other
detectors, this button is used for checking receipt of messages
only.
2.
Button 2 is not operable in Astra-421 ver.RF2 and Astra-
4511 ver.RF2.
- Press the appropriate button and direct the laser beam at the
detector LED.
- Irradiate the LED for 1 second.
- Release the button.
Within no more than 5 seconds, the detector should indicate its
current status.
