ENVIRONMENTAL NOISE CONTROL SYSTEM
MK2
The Sentry MK2 basically performs the same functions as the original Formula Sound Sentry but
with added features and options.
• New case design provides easier connections via cable entry knock-outs and screw terminals
• A choice of internal microphone (supplied factory fitted as standard) or external microphone
may be selected
• Removable cover provides access to all connectors and settings. Anti-tamper seals are
provided.
• Anti-tamper microphone circuitry is incorporated with a front panel indicator.
• Dual mains voltage operation is standard (internally switchable)
General Detail
The Sentry was designed to help solve some of the environmental noise problems encountered at
entertainment venues and in working areas.
The unit was designed to be as versatile in use as possible and features a large bar graph
display. 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.
The Sentry may also be used as a stand alone display unit indicating sound pressure levels or in
industrial applications to switch on warning lamps or illuminated signs advising the use of ear
defenders when the safe noise level is exceeded.
It is microphone driven and has its own built in microphone.
The Sentry 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)
The Sentry is provided with connectors to interface with a range of equipment, plus internally
selectable options to make the system as versatile as possible.
Our technical department is always on hand to advise when unusual applications are
encountered.
