u Operates on 24 VDC, filtered or unfiltered

u Field‑selectable settings for temporal (Code 3) or

continuous horn

u High sound output (90 dBA at 10 ft [3 m])

These Wheelock mini-horns are dual‑tone alarm
devices listed for indoor use under UL464 for Audible
Appliances. They combine a low current draw for a
high sound output and offer field-selectable tone
settings for temporal (Code 3) or continuous horn
tones. They use either filtered DC or unfiltered full
wave rectified (FWR) input voltage. All inputs are
polarized for standard reverse polarity supervision.
They can be synchronized when used with the SM
(single) and DSM (dual) Synchronization Modules or a
compatible control panel. If not synchronized, the
temporal sound patterns could overlap and not be
distinctive.
Available in red for high visibility or off‑white to blend
in with room decor, these notification appliances offer
the durability of high impact thermoplastic
construction, easy installation through two‑wire
circuitry and single‑gang box compatibility. They are
ideal audible notification appliances for signaling
alarms in individual rooms in apartments, hotels,
motels, and offices.

Sound Output (UL Reverberant Room) at 10 ft (3 m)

Continuous: 16 VDC: 79 dBA

24 VDC: 83 dBA
33 VDC: 85 dBA

Temporal (Code 3): 16 VDC: 75 dBA

24 VDC: 78 dBA
33 VDC: 81 dBA

Notice

The sound output for the temporal Code 3 is
lower than in Continuous mode because the time
that the horn is off is averaged into the sound
output rating. While the horn is producing a tone
in temporal Code 3 modes, its sound pressure is
the same as the Continuous mode.
