5 - OUTPUTS AND LED INDICATORS
5.1 - Operating principle of the relays
The factory setting establishes that both relays function according to the principle of standby current. The
operation principle of the relay can be set according to the following table by using jumpers, if fitted on the
card. In this regard, the housing of the detector must be opened carefully (see table 7).
- Warning! On the card there are components which are sensitive to static energy. When
working with the device open, appropriate precautions are required. Do not touch the compo-
nents or conductors! The warranty will be nullified for damages caused by improper handling!

5.2 - LED indicators
The green LED indicates that the detector is ready for operation. The red LED, depending on the occupa-
tion status of the loop, indicates the activation of the relay output (see table 8).

5.3 - Loop frequency indication
About 1 s after the adjustment of the detector, the loop frequency is indicated by flashing signals on the
green LED. First of all, the 10 kHz location of the frequency value will be displayed. For each frequency
value of 10 kHz, the green LED of the detector channel will flash once. After 1 sec. the 1 kHz position will
be displayed in the same manner. If the value at the position of 1 kHz is '0' the LED will flash 10 times.
The 1 kHz position flashes are slightly shorter than the 10 kHz position flashes.
Example of 57 kHz loop frequency:
6 - ELECTRICAL CONNECTIONS
– Incorrect connections can cause faults or hazards; therefore ensure that the specified con-
nections are strictly observed and performed by experienced and qualified personnel.
– Hook up the unit with the electrical power shut off.
