Trigon Electronics
"Excellence in Security Telecommunications Engineering"
Trigon Electronics has been in the "access control" market since 1976. It was started out of necessity as the founding owner wanted a device to allow access to his apartment building, thus a company was born. Numerous new products have been developed over the past two years, including expanding into the emergency tower market.


The Castlegate II is a single residence, hands-free telephone entry system for use at a private residence. It uses the existing telephone line for communication and access control. However, since calls do not go into the telephone company network, there are no charges for calls made from the system.

Visitors initiate calls from the entrance by pressing the "call" button on the illuminated faceplate. The call is received in the residence as with any other call. Residents can discern between entrance calls and regular telephone calls due to the unique ring modes available with the Castlegate II.

Residents, employees, or guests can access the premise immediately by entering their personal code on the Castlegate II keypad
