P-TEC VOICE PAGING SPEAKER S-525

INTRODUCTION

Clarity P-TEC Voice Paging Speakers are suitable for voice paging as well as background music. The S-525 is a 70 Volt model with adjustable taps and volume control. P-TEC speakers consist of a 3.6 inch cone speaker mounted in a unique surface-mount baffle. The baffle is designed for mounting on acoustic tile, such as those normally found in suspended-ceilings; and can be mounted without cutting large holes in the tile. The mounting pins can be removed for mounting in a hard ceiling. The speaker housing has screw holes for securing speaker without mounting pins. Although the P-TEC speakers are designed especially for standard suspended ceilings, they can be used on many types of ceiling materials. P-TEC speakers are not suitable for use in plenum ceiling environments.

1. Install the Quick-Connect connector on the wire. Use pliers to close the connector over the wire. The connector can be removed by prying it open with a screwdriver, and can be reused several times (See Figure 2).

Figure 2. Attaching the Reusable Quick-Connect Connector

1. Connect the power-tap wire to the gold (+) terminal (See Figure 3).

2. Arrange the unused power-tap wires neatly inside the speaker housing and tape them to the inside of the housing.

Figure 3. Connecting the Tap Wire

Suspended Ceiling

Note: Wrap wires around strain relief posts so speaker wires will not pull free.

1. Lift the adjacent ceiling tile and slide it out of the way.

2. Install the speaker by inserting the mounting pins through the ceiling tile, and hold the speaker in place.

3. Place the wire and washers, and speaker mounting clips over mounting pins (so pins slide through clips).

Figure 4. Clarity P-TEC Installation

Note: Washers provide isolation from the pins if the back of the tile is covered with metal foil.

1. If necessary, adjust paging volume after installation. The volume control is located on the side of the speaker. Use a small screwdriver to turn the control.

2. Install the volume control cover found in the accessory pack.

Note: The music volume should be adjusted at the paging amplifier or music source. Adjust paging before adjusting background music.

Maintain Speaker Phasing

When using multiple speakers in a single run, keep speakers in phase by connecting the speaker wires to the same spike on each speaker (Either wire can connect on either spike, as long as the pattern is followed on each speaker). The gold spike is the plus (+) terminal (See Figure 5).

Handling Shielded Speaker Cable

If you are using shielded speaker cable, splice the shield wire at the speaker location so a continuous shield is maintained. When connecting a single speaker, or the last speaker on the run, clip the shield wire where it emerges from the outer insulation on the speaker cable.
