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.

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

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.
