;
3. Install detector power sources –
BACKUP
first then
MAIN
;
4. Assess the level of acoustic noise at the installation place by the indicator glowing green
(no interference if there is no glow). If interference is present, their source should be
eliminated;
5. Set the switches
#1
,
#2
,
#3
to
ON
. The indicator starts flashing green 1 time per second;
6. Close the detector cover;
7. Apply a few blows to the protected glass (in the part farthest from the detector) with a
steel ball with a diameter of ~21mm suspended on a thread 35 cm long, deflecting it to
the angle indicated in Table 2.
