Standard Light Distribution

Vertical Dispersion

Horizontal Dispersion

A polar light distribution in both horizontal and vertical directions is mandated for the strobes by the Standard UL 1971 for the Hearing Impaired, with

specific minimum intensity percentages as shown in the graphs above. With its specially designed lens/reflector system, the PS12/24ADA Strobe

Retrofit Plate Series meets or exceeds these requirements at all angles.

Engineering Specifications

Sounder/Strobe shall be a System Sensor Model ______

listed to Standard UL 1971 for the Hearing Impaired and

shall be approved for Fire Protective Service. Sounder/

Strobe shall be wired as a Primary Signaling Notification

appliance. Sounder/strobe shall also comply with the

Americans with Disabilities Act requirements for visible

signaling appliances. Sounder/Strobe shall operate on 12

or 24VDC from a regulated DC supply or full-wave

rectified, unfiltered supply. The sounder/strobe shall be

powered from a non-coded power supply. Sounder/Strobe

shall have no measurable in-rush current in excess of

operating peak current. Visual signaling devices are to be

installed in all non-sleeping/corridor and sleeping areas

per plans and specifications. The strobe light shall consist

of a xenon flash tube and associated lens/reflector system.

All sounder/strobes shall be capable of semi-flush wall

mounting to a standard 2

separate mounting plate or to a 4

with a separate mounting plate.

General Description

All PS12/24ADA Series integrated sounder/strobes are

suitable for primary signaling in public mode life safety

applications. The sounder/strobes can be connected to the

alarm indicating circuit of a UL listed fire alarm control

panel. They are compatible with DC line supervision.

Panels may have full-wave rectified, unfiltered power

supplies. The sounder/strobes are available for either

24VDC operation, with 15, 15/75, 75, or 110 cd light

intensity, or for 12VDC operation with 15 or 15/75 cd light

intensity. They feature low current draw with no

measurable in-rush in excess of peak current. The

sounder/strobe is intended for wall mounting only to a 2

″

electrical backbox. Mounting to a 4

″ square electrical

backbox can be done with the addition of the PS-FP

accessory mounting plate.
