(CLIP test transmission). The other LEDs indicate the level of signal received by the
GSM telephone. LEDs A and B blinking simultaneously indicate logging into the GSM
network. In case of an unsuccessful GSM network login, blinking of the other LEDs
provides information on the troubles (see: Fig. 3).

Fig. 3. Examples of LED indicated statuses.
A (LED A is blinking, the other LEDs are lit
up)
– GPRS transmission is going on; signal level: 3.
B (LED B is blinking, the other LEDs
are lit up)
– SMS message is being sent or converter is calling (CLIP test transmission);
signal level: 4.
C (LEDs are blinking)
– logging into GSM network.
D (LEDs are blinking)
- logging into GSM network has failed; missing SIM card.
E (LEDs are blinking)
– logging
into GSM network has failed; missing PIN code.
F (LEDs are blinking)
– logging into GSM
network has failed; invalid PIN code.
G (LEDs are blinking)
– logging into GSM network has
failed; SIM card has been blocked after three attempts to use an invalid PIN code (PUK code
must be used to unblock the SIM card).
Description of terminals:
+12V
- power supply input (12 V DC ±15%).
COM
- common ground.
TIP, RING
- terminals for connecting the control panel telephone communicator.
Note: Do not connect the telephone exchange or any devices simulating the analog
telephone line to the TIP and RING terminals.
FT
- OC type output, indicating a problem with logging into the GSM network.
It activates approx. 2 minutes of the problem occurrence. When active, it is
shorted to common ground and remains in this state until logging into GSM
network. The problem with logging into the GSM network can be caused by:
– unavailability of GSM network (out of range),
– missing or damaged antenna,
– entering an invalid PIN code,
– missing SIM card.
Some additional information can be provided by LEDs on the electronics board
(see: Fig. 3).

NSTALLATION
All electrical connections may only be made with disconnected power supply.
It is not recommended to power up the device with disconnected antenna.
