Troubleshooting guide
Q. The unit will not power up. No LEDs on.
A. Check alarm or CAT5 cable has not been used to power the device. If it has, the warranty will
be void. Please remove and replace as per instructions.
Q. The unit powers up but is not showing network reception or will not respond to SMS.
A. This means the unit is not able to detect the network for some reason.
-Check the SIM card is activated and has calling credit.
-Power off the unit, remove the SIM and check it in a mobile phone to verify it can make a call.
-Check the SIM does not ask for a PIN code when put in a phone. If it does, then disable the PIN
code request.
-Check the SIM is a standard voice SIM and not a data only SIM for a tablet.
-Check the reception is strong. Poor reception is not sufficient.
- Check alarm or CAT5 cable has not been used to power the device. If it has, the warranty will be
void. Please remove and replace as per instructions.
-Power off, remove the SIM, use fine sand paper or a sharp object to lightly clean the SIM pads
and contacts on the GSM unit. Gently bend the contacts upwards so that they make better contact
with the SIM and try again.
Q. The caller ID part does not work.
A. Be sure to program the caller ID part under 72 feature. If your number is a private or number
withheld, then it will not work.
-Even if you have already programmed a number to receive a call from the device, if you also
want that number to have caller ID access, it must be programmed under the 72 feature also.
-Ensure the number is entered as you would normally dial it from another phone.
Q. The keys do not work when the device calls a phone.
A. Check if you can hear the relay clicking at the gate when the keys are pressed during a call. If it
can be heard, then the system is working, check wiring between the relay and the lock or gate
panel. If the relays do not make a clicking sound, then check this feature on a different mobile cell
phone or landline. If it works on a different phone, check the settings on the phone in question
under DTMF tones.
Failure of DTMF tones to operate correctly is also a symptom of low reception. Check steps above
on improving reception. Try pressing the buttons longer when attempting to activate the gates or
door.
Also check that the relays are not already latched with the *22# command. If they are latched,
they need unlatched before the trigger keys will work.
Q. The system was operating the gates fine, but now it will not trigger the gates.
Most of the time, this is cause by the user accidentally latching the relay. This latches the output
relay permanently on. Send the intercom the following SMS *22#. The device should reply with a
message detailing the relay status.. If it has been latched, then t
he message will state “the relay is
ON”. In this case refer to the user guide to read how to unlatch it again.
Q. The unit no longer calls out to phones but I can make a call to it from my phone
.
A
– Check there is balance on the SIM card.
A
– Switch off the power, remove the SIM, put it into a phone, and check that a call can be made
from a phone. This will verify if the SIM is still working and in service.
