Description

The Speaker Base (PAD100-SPKB) is a wall or ceiling mount adjustable speaker that may be utilized in a variety of applications. The speaker is designed to meet code requirements for audio and voice communications. The PAD100-SPKB offers dependable evacuation signaling. The PAD100-SPKB provides a 25 or 70.7 VRMs speaker with field selectable power taps of 1/8W, 1/4W, 1/2W, 1W, 2W or 4W. The frequency range of the PAD100-SKPB is 400-4000 Hz and is suitable for 520 Hz low frequency tone applications. The base has a locking feature for the sensor that may be used or removed in the field. The panel will support any combination of sensors or modules on the SLC. The PAD100-SPKB does not consume an address on the loop. The PAD100-SKPB can be mounted to a 4” by 2-1/8” deep square box or the LFSBBB-W back box.
The Speaker Base is not an addressable device. Independent control of the speaker base requires a PAD100-SM speaker module.

Detector Base Mounting

PAD100-SPKB should be mounted directly on an electrical box (see Figure 1) or the LFSBBB-W back box (see Figure 2). The PAD100-SPKB mounting holes are configured for a 4” x 2-1/8” deep square box. Use a box for each base and run the power circuit to all base locations. Fig. 1

Locking Feature

Eliminate the Locking Feature
PAD100-SPKB include a locking feature that prevents removal of the detector and removal of the base cover without using a tool.

To eliminate this feature, break off the locking tab and then install the detector. See Fig. 3. Fig. 3
Removing of Detector Head from Base: To remove the detector from the base once the locking feature has been activated, insert a small screwdriver into the slot on the base to push the plastic tab while simultaneously turning the detector head counter-clockwise. See Fig. 4.
To remove the base cover from the lower enclosure once the locking feature has been activated, insert a small screwdriver into the slot on the on the base to push the plastic tab while simultaneously turning the detector head counter-clockwise.

Wiring Diagrams

The SLC supports NFPA wiring Class B, A and X. In the Class A arrangement, two separate conductors would return from the last detector base to a listed compatible Fire Alarm Control Panel (FACP). The frequency range of the PAD100-SPKB is 400-4000Hz and is suitable for line supervision. Fig. 5

System Considerations

To select the proper wattage input for the speaker, move the jumper to the appropriate pin.
Always maintain electrical isolation between speaker and strobe wiring on combination units.
Do not exceed 130% of rated speaker voltage. If excessive distortion is heard, check amplifier for signal clipping. If clipping exists, reduce either amplifier input or gain.
