A GSM system avoids the need to run cables from the entrance to the premises. Instead, an onboard sim card allows the system to make telephone calls, contacting the occupant’s landline or mobile.
The GSM system offers the ability to call up to eight numbers in a cascade sequence, so you’re not restricted to just one recipient. If an engaged tone is recognised, it will automatically begin dialling the next number to avoid any answer machines.
Other features available include:
- LCD name tags which allow each button to be renamed remotely (saving engineer visits)
- Up to 900 authorised telephone numbers which can call the intercom to gain entry
- Easy system programming which can be done using either our smartphone app, PC software or hosted programming service.
We also offer custom engraving, to give your intercom a more bespoke feel.
