BFT-SWITCH-4G GSM Cellular Gate Opener and GSM Alarm Signalling Device User Manual
BFT-SWITCH-4G GSM Cellular Gate Opener and GSM Alarm Signalling Device

Overview of System

Please read this entire manual before attempting to install this system.
This system should only be installed by a professional automatic gate installer or access control specialist dealer.
It is recommended that the system be set up, configured, commissioned and tested on a workshop bench before taken to site for installation.

Site Survey

Before installing this system, you need to be sure that there is good mobile GSM cell coverage in the area it is to be installed. It is recommended that you conduct a site survey, and check reception on the site for a GSM network. If reception is poor in the area, then this system is not recommended.

SIM Card

You will need a SIM card in order to use this system. It should be a regular voice and SMS text SIM card. Do not use a data only SIM, as this is only for tablets and will not work in the unit.

SIM Card

  1. Ensure the SIM has calling credit, and can make and receive calls on a mobile cell phone.
  2. Check that the SIM is not locked to a phone and can be used in other devices.
  3. Check that the SIM does not have a PIN code request.
  4. Disable voicemail service on the SIM.
  5. You are now ready to begin programming.

Power

TIP: Most technical calls received are due to installers using CAT5 or alarm cable to power the unit. Neither are rated to carry enough power (2 amp peak). Please use following cable…

Warnings
Up to 2 metres (6 feet) – Use minimum 0.5mm2 (18 gauge)
Up to 4 metres (12 feet) – Use minimum 0.75mm2 (16 gauge)
Up to 8 metres (24 feet) – Use minimum 1.0mm2 (14 gauge)

Using insufficient power cable thickness will cause excessive stress on electronic components, and therefore void the manufacturer’s warranty.

To avoid such problems it is recommended (and is good practice) to locate the power supply as close to the device as possible. This avoids power cable noise and interference and enhances the lifetime of the product.

Inserting the SIM card

Note: This unit is a dual 3G/4G system, operating on either 3G or 4G network frequencies.

Inserting the SIM card

Please ensure the SIM card is a 3G/4G compatible Nano SIM card.
The SIM may also be 2G capable as well, as long as both the SIM and the network also support 3G/4G. Do not use a SIM card for a tablet, as these only support data, and do not support voice and SMS. You simply require a mobile phone type SIM card.

Powering Up

Perform a final check of wiring and ensure the antenna is connected before switching on the power. Once the power is switched on, the power LED should illuminate.

Powering Up

TIPS: My GSM LED is still searching…

  • Check the SIM card is registered and can make a call in a phone.
  • Check the SIM card is seated correctly. Power off, clean the contacts on the SIM and the GSM unit, and reinsert the SIM.
  • Check power cable distance and thickness.
  • Increase antenna height.
  • Change network.
  • Move antenna away from metal objects.
  • Fit a high gain antenna.

Pass Codes

CAUTION: Take care when changing pass codes. There are 2 levels of 4-digit code (both must be different):

  1. Engineers/Programmers code (default 9999)
  2. Access/user code (default 1234)

You may wish to change both from their defaults for security.

Pass Codes

If changing default codes, then you will now need to update the client list before you can do any further programming.
If the 1234 user access code is changed, then you will also need to change it on the home owners app.

SMS Strings:
9999#01XXXX# (X=new programmers code)
9999#02XXXX# (X=new user access code)

Relay Times

Relay default trigger times are 1 second. Use this feature to change a relay for a longer time perhaps for a magnetic door lock or to make one relay a momentary relay and the other a 1 hour relay for example.

Relay Times 

TIP: Iphone users will be taken to SMS screen to confirm message. Android devices will auto send the SMS.

SMS string for relay 1:
9999#50XXXX# (X=time in seconds, 1-9999)

SMS string for relay 2:
9999#51XXXX# (X=time in seconds, 1-9999)

Notifications

This feature is commonly used to allow one home user to receive SMS alerts each time the INTERCOM is used to trigger the gates and grant access.

Notifications

SMS string for turning ON or OFF:
9999#80X# (X=2 to enable. X=1 to disable)
SMS string for entering phone number to receive notification:
9999#78XXXXXXX# (X=cell phone number) 78*# to delete.

SMS string for entering text to display:
9999#79XXXXXXX# (X is any text message you wish to display on the phone. E.g. Gates Opened)

Auto Relay Trigger Times

Create up to 40 automatic time clock events to trigger or latch/unlatch gates (depending on gate system setup).
For auto closing gates, send latch command at the desired opening time, followed by a separate unlatch event to close at the desired closing time.
For step-by-step operated gates (non auto-closing), then send a momentary trigger command at the time required to change the state of the gates from open to closed or closed to open.

Clock Sync

The unit has an internal time clock counter, which reads the time from an incoming SMS message, and uses this to calibrate its time clock.

For power failure events, this feature allows the unit to send a SMS to itself after a power failure.
Simply press the button and the app will send a SMS string to the intercom storing the phone number from the SIM card inside memory.

TIP: Use this if your area experiences regular power cuts and your client is using timed features.

Note: Using this feature will cause the unit to be busy for 2-3 minutes after a reboot. Please be patient with programming etc after a re-boot.

Clock SyncClock Sync

TIP: 9999#86*# will delete this number again

Daylight Saving

For regions where there is a 1 hour time shift for daylight saving, it can be useful to have the intercom send itself a SMS every set number of days to re-synchronise the internal clock. The intercom will do this anyway each time a SMS is received.

Daylight Saving

Do not disturb 

This feature allows the alarm input on the device to be active during pre-set times, and ignore button presses all other times.
Use this screen to set the ACTIVE times and days for the button.

Do not disturb 

To activate, enter the following code:
1234#21#ON# (change ON to OFF to disable again)

After Hours / Out of Hours 

If you have activated the do not disturb feature, the push alarm input will not call anyone after the pre-set time threshold. However, sometimes it is useful to have the device call a different number after hours. For example, in commercial premises it can call the office phones during business hours, and then call a security guard after hours.

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.

  • ven 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 the 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.
