Optional Accessory Installation — Priority Page Sensor Kit

The Priority Page Sensor Kit momentarily silences classroom audio whenever a page is made from a public address (PA) system.

For detailed information, see the Priority Page Sensor Kit Installation Instructions, supplied with the device.

NOTE: The Priority Page Sensor works with traditional 25 V or 70 V and 4/8 ohm PA systems. It is not

designed for, and may not work properly with, two-way intercoms or systems that are IP-based or that use

digital clocks.

Installation Procedure

WARNING: RIsk of serious personal injury if installation is not done correctly. All structural steps,

anchoring, and electrical installation should be performed by qualified personnel in accordance with local and national building codes, fire and safety codes, and/or local and national electrical codes.

To meet the plenum rating requirement, the Priority Page Sensor assembly must be installed in a UL-compliant junction box with a cover. All cables to and from the sensor must be plenum rated.

1. Choose a suitable location for the sensor near,

and in series with, the speakers.

2. If the sensor is to be located in a plenum

space, the junction box (provided) can be

used. Knock out an opening at one end of the

box and attach the cable clamp (see figure at

right). Secure the box at the sensor location.

3. Disconnect the PA system speaker cable from the

speaker.

Remove the outer protective jacket from the

speaker cable to expose the two speaker wires

from the sensor to the speaker (as shown at right).

Do not remove the inner protective jackets that

B UL-Compliant Junction Box and Cover

cover the individual wires.

If the sensor is to be located in a plenum space,

feed a loop of one of the exposed speaker wires

through the cable clamp into the junction box.

The other wire must bypass the sensor to be

connected later directly to the speaker.

4. Open the top of the Priority Page Sensor and loop

the speaker wire that is inside the junction box

tightly around the top part of the sensor.

NOTE: Loop only one of the speaker wires

around the sensor cover. Do not loop both

wires. Polarity need not be observed.

The other speaker wire must bypass the sensor and connect directly to the speaker.
