GENERAL:
The Cluster Speaker Strobe Assembly is designed for indoor ceiling mounting or indoor wall mounting, in high ambient noise level environments. The Cluster
Speaker Strobe is a speaker/visual alerting system, equipped with up to 4 UL Listed STH-15SR supervised horn loudspeakers and a UL Listed High Candela 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. Each loudspeaker
meets or exceeds the UL Standard 1480 (Speakers for Fire Protective Signaling Systems).
The RSS-24MCCH Strobes can provide a non-synchronized strobe signal when connected directly to a Fire Alarm Control Panel (FACP), or provide a synchronized
strobe signal when used in conjunction with a Sync Module (SM) or Dual Sync Module (DSM). The Series RSS Strobe Appliances are UL Listed under Standard
1971 (Emergency Devices for the Hearing Impaired) for Indoor Fire Protection Service. The Series RSS Strobe Appliance with amber, blue, green or red lens is UL
Listed under Standard 1638 (Visual Signaling Appliance) for Private Mode Emergency General Utility Signaling. The strobe uses a Xenon flashtube with solid state
circuitry enclosed in a rugged Lexan® 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.
