GSM-3B & GSM-3BK Intercom system

This popular GSM Intercom system makes 2 way audio phone calls when the call button is pressed. No longer let visitors realise that premises are unoccupied when they push the button and no one answers as with a conventional Intercom.

 

When a visitor arrives, they push the call button and the unit generates a high quality audio call to up to 3 numbers to announce their presence. Should the person taking the call wish to allow entry, they simply push a button on their telephone handset to release the on board relay.

 

• Single button entry system
• Stand alone unit with front panel and integrated GSM
  

• Calls up to 3 numbers when activated (landline or mobile)
• Allows 100 phone numbers to call the system for free to trigger the on-board relay to activate gates or doors
• Simple to install, setup and operate

Not only is this system offering two way speech, Caller ID access control allows known numbers to call the unit. When the call arrives, it is immediately dropped and if the number is known, the gates or door is released.

 

Ideal for using mobile phones instead of 'key-fobs' in that up to 100 users can operate the gates in this way.
