GENERAL:
The Wheelock STH Cluster Speaker/Strobe Assembly is designed for indoor ceiling mount, in high ambient
noise level environments. The Cluster Speaker/Speaker Strobe is a speaker/visual alerting system, equipped
with up to 4 UL Listed STH-15SR supervised horn loudspeakers and a UL Listed Eluxa LED Strobe, mounted
to a NEMA galvanized steel enclosure, 10"W X 10" L X 6"D. The Strobe is mounted to a 4" deep backbox,
which is then mounted to the steel enclosure. Speakers and Strobe are pre-wired to the internal terminal
block. The speakers can be wired for one or two speaker circuit operation.
The STH-15 loudspeaker provides multiple power requirements with high dBA output at each power tap.
STH-15 offers a choice of field selectable taps, 1 to 15 Watts for either 25VRMS or 70VRMS audio systems.
The Series STH design incorporates a compression driver, mounted on a double re-entrant horn for maximum
output at minimum power across a UL rated frequency range of 400 to 4,000Hz and an anechoic range of 400
to 14,000Hz. The speaker line inputs are compatible with standard supervision of circuit wiring by a Voice
Control Panel. A capacitor is wired in series with the multi-tap transformer for this purpose.

The Wheelock Eluxa Multi-Candela Strobes can provide a non-synchronized strobe appliance when
connected directly to a Fire Alarm Control Panel (FACP), or provide a synchronized strobe appliance when
used in conjunction with an FACP that incorporates the Cooper Wheelock sync protocol, a Dual Sync Module
(DSM), or the Wheelock Power Supply. The Eluxa Strobe Appliance is
is enclosed in a rugged polycarbonate lens to provide maximum visibility and reliability for effective visible
signaling. All inputs are polarized for compatibility with standard reverse polarity supervision of circuit wiring
by a FACP.
