3 After the Detector energizing, self-testing process is activated. The 

process is accompanied by the LED indicator blinking once per second. 

The LED indicator blinking red for 30 sec means a possible fault. 

In case of the situation repeat after the Detector is restarted, it is 
recommended to substitute the Detector.

4 The «DISARM» command ensures sound processing blocking in 

order to avoid false alarm in the rooms during labor hours and to save 
the battery charge. The «ARM» command transfers the Detector to 
a standby mode.

5 The «Identification» command allows to find the Detector assigned 

to the respective monitored zone.

Detector Installation Examples

Correct Detector installation options see Figures 3 – 7, the incorrect one – Figure 8 

Adjustment

Set the «1», «2» and «3» DIP-switches to the OFF position. Install 

the power supply batteries. Estimate the interference situation in the 
room (the green LED indicator should not  light up).

The green indicator lighting up means the high level of interference  

in the room. Remove the interference sources if possible.

Execute adjustment of the Detector as follows:
- set the «1», «2» DIP-switches to the ON position. After it shift        

DIP-switch «3» to the ON position – the «Adjustment» mode is 
displayted by the green LED indicator blinking once per second;

- close the cover;
- suspend a steel ball 21 – 22 mm in diameter on a 35 cm long thread 

near the farthest part of the monitored glass (ordinary, ornamental, 
armed, laminated), deflect it at an angle of 30 – 70° (see Table 4, 45° 
for hollow glass blocks). When the green LED indicator switches on, 
deliver a test blow.

In case the CP does not receive an alarm message after test blows, 

the Detector sensitivity must be increased by DIP-switches «1» and 
«2» (see Table 5).

- this method produces the most reliable results; however, for 

adjustment the Detector for monitoring a multilayer glass or a 
small area of glass, it is allowed to use an AFT-100 type electronic 
glass break simulator manufactured by the «DSC»  company  in  the                        
«Plat/Singl» mode or an APC type glass break simulator manufactured 
by the «Argus Security» company. Besides, a simulator should be used 
for adjustment the Detector to multi-glazed windows;

- check the correctness of the Detector adjustment with the Detector 

cover installed;

- after completing the Detector adjustment, set DIP-switch «3» to 

the OFF position.

Features and Recommendations

1 The Detector backup power supply is energized whereas the main 

battery is installed.

2 The LED indication is switched off automatically in 10 minutes 

after the cover is closed. To restore the LED indication lighting it is 
enough to open the cover.
