Installation and Setting Up For normal use, the Sentry requires direct connection to the mains supply, with the Controller sitting between the supply and the outlet sockets. This is a simple process but should be carried out by a qualified electrician. The installation process involves: Finding a location for the Sentry and Contactor Connecting the Sentry to the mains power supply Connecting the low voltage lines from the Sentry to the Contactor Connecting the Contactor between the supply and the outlets Setting the sound level limit (or limits, as two are available)

Sentry Music Noise Controller

Detailed installation instructions are included in the Sentry User Manual, which is supplied with the unit. The information on this page is intended as an overview so that you can see what is involved.

Mounting Position

The Sentry music noise controller should be mounted on a solid wall where it can be seen by the DJ or live band, preferably at a height of at least 2.5m from the floor to discourage tampering. If your layout does not allow for this, a remote display, reset switch and microphone are available to help.

The Sentry unit is fixed to the wall using three screws.

Cabling

The box has "knock outs" where the mains and signal cables can enter. Rear cable entries are also available to provide a very neat installation.

The Sentry gets its power from the mains supply (120 to 240 VAC). In its normal configuration (controlling power to the audio system), a low voltage signal is then carried to the Contactor. This allows the Sentry to be mounted away from the Contactor without the need to run high voltage cabling.

The Contactor is then connected between the mains supply and the outlet sockets that are available for the audio system.

All wiring should be carried out by a qualified electrician and in accordance with the national regulations.
