Sentry 2 Button Horz Controller & Auxiliary (DCOM)


The Sentry unit is designed for general purpose situations, a PSTN Doorstation featuring an interactive voice prompt for quick and easy programming. (Power supply (PSU) is supplied).

The Sentry Doorstation ranges from one to six buttons and can be expanded up to sixteen buttons on a custom panel. The standard panel (130mm X 270mm) is made from  304 stainless steel. The metal buttons and keypad (4×3) are made to be vandal resistant.

Panels are available in either vertical or horizontal, and can be anodised aluminium or stainless steel. If you require the panel to be made of different material (ie. Brass, gold-plated, etc), this too is available upon request.

With programmable auto dial buttons, the Sentry doorstations are a user friendly solution for controlled entry.  In the event of noisy environments a push-to-talk feature can be implemented in order to overcome the background noise level while on a call. (Available on all models).
