Door Entry Systems


GSM Door Entry System employing mobile phone technology to communicate and operate doors and automatic gates. Based on the 4000 Series door entry panel design, the GSM amplifier is totally self contained and only requires an external power supply and antenna while having the flexibility to combine with the full range of the 4000 series module features.

GSM Audio Intercom and Access Control

The GSM Door Entry System retains all the facilities of the 4000 Series which can include multiple doors, coded access, proximity access and bio-access features.

Available from a one button kit to a ten button system, they can all have up to 250 built in access codes dependent upon the SIM card used. This allows a user or users to call the entry panel and activate the lock output relay at no charge to the caller. Each button on the door panel can be programmed with two telephone numbers, allowing the system to divert a call if the first number is busy or not answered.

Push to exit and auxiliary inputs / outputs (to either send an SMS message or trigger an output) along with a dry contact timed lock output relay are standard. Programming the unit is carried out using either SMS text messaging or by dialling into the unit and using a telephone keypad.

Programming options include the facility to program the telephone number, program the divert number, lock relay time, call time, microphone and speaker volume as well as many other security features.
