Noise Control & System Protection

Typical Sentry Installation

For an entertainment venue

The Sentry features a large bargraph meter to indicate the actual noise level.
The red section on the right is larger to clearly show when the permitted level is exceeded.

The built in microphone minimises tampering. Connections are provided for a remote microphone.

With an Internal mic

The unit must be mounted in the noise area and adjusted to operate in the range 85dB to 120dB (SPL), Linear or 'C' for entertainment venues.

With an External mic

The mic must be mounted in the noise area.

The Sentry is not restricted to this type of application.
Any function which can be controlled by a relay or switch can be controlled by the Sentry.

WARNING

CORRECT WIRING PRACTICE MUST BE OBSERVED ON ALL 240V MAINS CONNECTIONS. IF IN ANY DOUBT CONTACT A QUALIFIED ELECTRICIAN.
