Selectable Output Speaker/Strobe Specifications
Architectural/Engineering Specifications
Speaker/Strobe shall be a System Sensor Model _____________ listed to UL 1480 and UL 1971 and be approved for fire protective signaling systems. Speaker
shall be capable of operating at 25.0 or 70.7 nominal Vrms, and shall have a frequency range of 400 – 4000 Hz. Speaker shall have power taps that are selected
by shunts. The strobe shall consist of a xenon flash tube with associated lens/reflector system and operate on either 12V or 24V. The strobe shall also feature
selectable candela output, providing options for 15 or 15/75 candela when operating on 12V and 15, 15/75, 30, 75, or 110 when operating on 24V. The strobe
shall comply with the Americans with Disabilities Act requirement for visible signaling appliances, flashing at 1 Hz over the strobe’s entire operating voltage range.

Reversible Strobe Feature
Removing the strobe screw and lifting the strobe assembly out of the rib slot
allows the strobe to be rotated 180° and remounted to the base resulting in a
left-mounted strobe configuration.

Explanation of Published Strobe
Specifications
In May 2004, Underwriters Laboratories changed standard UL 1971 to
require that operating current measurements are made using RMS (root
mean square) instead of peak or average values. RMS measurements more
accurately predict the power consumption of a device since they take into
account the entire current draw profile including surge, repetitive surge, and
peak values. The published RMS current is the maximum operating current of
that device within its operating voltage range. This current maximum may or
may not occur at the endpoints of the voltage range.
In May 2004, UL also changed the way they list the voltage range of a device.
All 12V products will be listed between 8–17.5V and all 24V products will
be listed between 16–33V. These devices are considered “regulated.” Any
product that does not operate within these ranges will be listed as a “special
application” with its operating voltage specified on the device.
