General Description

The National Fire Protection Association has published standards and recommended practices for the installation and use of the above appliances. It is recommended that the installer be familiar with these requirements, with local codes, and any special requirements of the local fire authority having jurisdiction. The Piezo electronic sounder and signaling strobe are intended to be connected to the alarm indicating circuit of a UL-listed fire alarm control panel. Both are compatible with DC line supervision. The electronic sounder can be connected to either 12 or 24 VDC panels. Models PS2415ADA, PS2475ADA, PS24110ADA, and PS241575ADA require 24 volt panels. Models PS1215ADA and PS121575ADA require 12 volt panels. Panels may have full-

Figure 1. Vertical and horizontal light distsribution:

wave rectified, unfiltered power supplies. The strobes produce one flash per second (nominal) with continuous nominal voltage applied.

The sounder/strobe strobe is rated for 0° to 49° C and is NOT suitable for outdoor use.

The rated light output of the PS2415ADA, PS1215ADA, PS241575ADA, and PS121575ADA is 15 cd (See Figure 1).

The rated light output of the PS2475ADA is 75 cd (See Figure 1).

The rated light output of the PS24110ADA is 110 cd (See Figure 1).

NOTE: The 15/75 cd strobe has been measured to be 75 cd

@ 0° viewing angle.

Greater than 90 dBA measured in anechoic room at 10 feet, 24 volts (see Figure 2 for other voltages); 79 dBA minimum measured in UL reverberant room @ 12V and 82 dBA @ 24V.

Figure 2:

NOTE: All models can be powered using full wave recti-

fied unfiltered supplies. Under no circumstances can PS24ADA series devices input voltage exceed 33 VDC or be less than 16 VDC (16-33Vrms for fullwave rectified, unfiltered supplies). Under no circumstances can a PS12ADA series device input voltage exceed 18.7 VDC or be less than 9.6 VDC (9.6 - 18.7Vrms for full-wave rectified, unfiltered supplies).

Installation

A. General:

Phillips head screws are used to attach PS12/24ADA to semi-flush plate or the electrical outlet box. Slotted head screws are used to attach semi-flush plate to outlet box. See Figures 3 and 4 for wiring methods.

NOTE: Do not loop wires under the terminal screw. Wires

connecting the device to the panel must be broken at the device terminal connection in order to maintain electrical supervision.

The PS12/24ADA is designed for wall mounting ONLY.

It is intended for mounting to a standard 2-1/2" deep single gang box which allows sufficient clearance for conduit entrance.

Voltage

All strobes must be mounted so that the top of the lens is 24 inches (61cm) below ceilings or as required by the authority having jurisdiction.

B. Sounder/Strobe combination mounting:

1. Surface Mount: (See Figure 5)

2. Semi-Flush Mount: (See Figures 6 and 7)

3. Semi-Flush Mount with Plaster Ring or Double Gang Box: (See Figure 8)

Installation procedures must conform to all applicable codes and the requirements of the authority having jurisdiction.

NOTE: The rated output of the sounder is specified at 10

feet. It cannot be assumed that the output will meet the NFPA standard of 15 dB over ambient noise at all locations within a room. Additional sounders may be needed to ensure sound output level complies with NFPA requirements.
