1.Introduction
This device can be used for phone access control of gates, doors or barriers. The unit can
store up to 20 telephone numbers. Any of these numbers can call the unit to activate the
relay output at no call cost or send a SMS text message to control the relay.
The unit will operate on quad band cellular frequencies operating in most countries. The
frequencies are 850MHz, 900 MHz, 1800MHz, and 1900 MHz..
2.Tips
1) Make sure there is adequate reception on site before deciding to install this system.
Conduct a site survey and use your mobile phone or third party app to check
reception levels first. Choose a SIM card which has good reception levels on site.
Low or even medium reception levels are not sufficient.
2) Bench test this device in your workshop. Program it and check it operates before
installing on site.
3.SIM Card
Before inserting the SIM card, check the following…
1) The SIM is a 2G SIM for standard models, or a dual 2G / 3G SIM for the 3G version.
2) The SIM must be a standard cell phone type SIM which supports voice and SMS text
messages. Data is not required for operation of this device. Do not select a tablet
SIM as these only support data, and do not support voice.
3) Check the SIM has credit, and can make and receive calls in a cell phone first.
4) Ensure the SIM does not have a PIN code lock. If so, disable this in a phone.
5) If the SIM was purchased along with a phone, it may be locked to that phone. Please
check the SIM can work in another phone or device. If not, ask your network service
provider to unlock it so that it can be used in another device.
You may now insert the SIM card, ensuring the power is OFF first.
CAREFULLY slide the holder in the open direction and then
open the SIM holder door.
Insert the SIM, close the door, and slide in the close
direction until it clicks.

4.Wiring
You may now connect power to the unit. The unit can accept 12-24v ac or dc. For gate
installers, 24v ac or dc is recommended. Please do NOT USE MAINS power, as this will
damage the unit and void the warranty.

Searching Network
Tip: Power cable should be less than 3 meters (10 feet). Do not use thin cables such as
alarm cable or CAT5 cable to power this unit. The standby current is 45mA, however this
increases to 200mA when dialling out, with spikes of current draw up to 2 amps.
Avoid using poor quality cheap DC power supplies to power the unit. The unit will work best
when powered from a 24v ac or dc supply, which is then regulated and smoothed by the built
in circuitry.
Power up the unit. After 10 seconds or so, the GSM LED should begin flashing. If this does
not happen, power the unit off, and check the SIM card is seated correctly, and power it on
again. Ensure the steps above regarding the SIM card have been followed.

5.Programming
The unit is programmed by SMS text message from a cell phone.
Check Reception
1-12
Poor 13-20 Medium 21-31
Good
If reception levels are low, take action! Either increase the height of the device to improve
reception or request a higher gain antenna from your distributor or change to another
network which may have better coverage.
Adding numbers for access…
You will need to enter the phone numbers of any phones you wish to have access. Note that
the unit only compares the last 6 digits of the incoming call with memory, so you can either
store the entire number, or simply the last 6 digits of the number. The programming format
beings with the programmer’s passcode, followed by #, followed by the function code,
followed by the data. Example as follows..
9999#720987654321#
PasswordParameter Telephone
number
Send the SMS *20# as shown, to the SIM card number
of the device. The unit should reply with the network
name and reception level between 1 and 31.
*20#
Signal level = 15
Note: Reception levels below 14 can give problems with
the relay operation or the unit will not receive calls.
Reception can increase and decrease depending on
the weather.
9999#720987654321#
Add a phone number
success
The example shown will store number
0987654321 in momnry. The unit will reply to
the SMS command with a SMS stating “Add a
phone number success” as shown to the right.
Note: 9999 is the default programmers
passcode.

Adding a service number
This is important for Pay & Go or Pre-Pay SIM cards. Many networks will de-activate a SIM
card if it does not make a chargeable call every so often. To get around this problem, this
unit can be programmed with a service number which it will call every 30 days. You can
have it call the home owner, or the engineer’s phone, or to avoid a nuisance call from it once
per month, it could instead be programmed to call a talking clock number in your country.
770123456789#
Parameter Telephone
number
You may test the caller ID feature by calling the device from a phone which has been stored.
The unit should ring only once or twice, hand up and trigger the relay. The relay is default for
a 1 second momentary click. If you need to change this, please refer to the full programming
table.
6.Installing
The enclosure is IP67 weather proof rated, and for best reception, the device should be
installed outdoors, high off the ground, away from metal objects and shrubs.
If you are using this for a barrier control, then you MUST use an external antenna OUTSIDE
the barrier enclosure, as the unit will not have reception otherwise.
Entrance Pillar
Use an external antenna on an
extension cable if reception is
poor.
Keep
away
from
ground.

The examples below assume that the default user code is 1234.
9. Using the APP
The user can call the SIM number of the intercom from their
phone. If their number is stored then the device will hand up
the call without answering and trigger the gates or door with a
momentary trigger.
The user can also send the following SMS text messages to
further control the unit..
Press to trigger gates.
For gates set for automatic
closing, press to hold open
More buttons..
-Check gate status N/A
-Check signal strength
-Check stored numbers N/A
For gates set for automatic
closing, press to allow the
gates to close again.
Information
The App is available for Android
and Iphone devices called
GSM-Gate.
Note: Before the app can be used,
the sim card number and SMS text
strings as shown above will needed
entered in the settings screen.
The App will send the SMS strings
for you, so you don’t need to
remember the codes.

10.Troubleshooting guide
Q. The unit will not power up. No LED activity.
A. Check power supply voltage at the unit. Reboot the unit and wait for LED flashing.
Q. The unit powers up but the LED is still flashing rapidly.
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 and
receive 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 GSM SIM, not 3G or 4G only SIM. If you are unsure, contact
your SIM card provider to verify. Frequency of operation should be any one of the
international quad band standards, 850 / 900 / 1800 / 1900 MHz.
-Check the reception is very good. Poor reception is not sufficient.
Q. The caller ID part does not work.
-Ensure the number is entered as you would normally dial it from another phone.
-Do not put the country code in front of the number.
International callers ringing the intercom may not work.
-For USA customers, did you try entering the number both with and without the long distance
1 before the number?
Q. The system was operating the gates fine, but now it will not trigger the gates.
Send the unlatch SMS, and try again. This will ensure the output relay is not held in its on
state..
Q. The system was working fine, but has stop recognising all numbers.
A. This can be due to using poor quality power supply. It is recommended that the unit is
supplied from a 24v ac or 24v dc supply, which is then regulated and smoothed by the built
in convertor.

11.Restore Defaults
This can be done by SMS, but in some cases, if the unit las locked up or if the engineering
passcode is forgotten or not known, then it may be necessary to initiate a hard reset as
follows..
1) Power off the unit.
2) Make a short circuit as shown on the wiring diagram for the hard reset.
3) Switch on the unit
4) Wait for 15 seconds.
5) Power the unit off, remove the short.
6) Power on again. The device should be defaulted.
Caution: All numbers will be erased when a soft or hard reset is carried out.
