SATEL
test
– the detector operates like in the normal mode, but the alarms are signaled by the LED (the
LED is lit for 2 seconds).
To select between normal mode and energy saving mode, use the E-SAVE MODE pins (Fig. 1).
The test mode is turned on for 20 minutes after inserting the batteries or opening the tamper
contact.
The detector monitors the signal path for correct operation. Failure of the signal path is indicated
by the LED (2 flashes every 40 seconds).
Every 15 minutes, the detector sends a transmission containing information on the status of the
signal path, tamper contacts and battery. Periodic transmissions are used to monitor presence
and operation of the detector. In the test mode, this transmission is indicated by the LED lighting
for 80 milliseconds.

1 - CR123A battery. The detector checks the
battery status. When the voltage is lower than
2.6 V, the low-battery information is sent
during each transmission.
2 - detector configuration pins:
E-SAVE MODE
- operating mode selection:
pins shorted – energy save mode;
pins open – normal mode.
PET MODE
- pet immunity option:
pins shorted – option enabled;
pins open – option disabled.
HIGH SENS.

sensitivity
selection:
pins shorted – high sensitivity (Fig. 2);
pins open – normal sensitivity (Fig. 3).
3 - LED indicator.
4 - tamper contact activated by detector removal from the back tamper unit.
5 - tamper contact activated by cover removal.
6 - pyroelectric sensor.
7 - scale for positioning of pyroelectric sensor against the lens (Fig. 9).
