Formula Sound 073/T Sentry Sound Limiter with Timer Option

The Sentry, designed and manufactured by Formula Sound, is a product which will help solve some of the environmental noise problems encountered in entertainment venues and industry today.

The Sentry works in conjunction with a relay or contactor and usually controls mains power. But the Sentry is not limited to this function; any function that can be controlled by a relay or switch can be controlled by the Sentry.

The Sentry has connectors provided to interface with a range of equipment, plus internally selectable options to make the system as versatile as possible. Although its main application is to control mains power outlets in entertainment venues it is not restricted to this application. Basically any function that can be controlled by a relay or switch can be controlled by the Sentry. These may include disconnecting loudspeakers, switching passive attenuators to reduce system volume or acting as the trigger into an active attenuator system. It is microphone driven and has its own microphone built in to minimise tampering.

The Sentry also incorporates the facility to operate at two different sound level thresholds which may be selected manually, by a remote key switch or similar, or automatically by a time switch (switches not supplied). This allows a venue to operate at different levels at different periods of the day. e.g. when near offices or shops. An integral timer is available as a cost option.
