GSM Intercoms

The GSM1000 wireless intercom allows you to grant access to visitors at your gate from anywhere in the world. You can have a 2 way conversation with the visitor, and grant access from your mobile or house telephone keypad! The unit will dial up to 3 numbers if required. With a remote master program feature, installers can modify settings and re-program the unit remotely. Built in volt free relay can be set for latched or pulse mode, for easy interfacing with most electric doors, locks or gates. Can be powered from a 12v d.c. power source.
