SERIES ET70WP-2475W LOW PROFILE WEATHERPROOF SPEAKER STROBE APPLIANCE
Use this product according to this instruction manual. Please keep this instruction manual for future reference.

GENERAL:

Series ET70WP-2475W Low Profile Speaker Strobe are for indoor/outdoor use. For outdoor applications the ET70WP-2475W must be wall
mounted to a Weatherproof Backbox (IOB). They are designed for multiple power requirements with high dBA output at each power tap.
This model offers a choice of field selectable taps, 1/8W to 8W for either 25.0VRMS or 70.0VRMS audio systems. The Low Profile design
incorporates a high efficiency speaker for maximum output at minimum power across a frequency range of 400Hz to 4000Hz, and features a
sealed back construction for extra protection and improved audibility. The Low Profile Speaker 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 a Sync Module (SM), Dual Sync Module (DSM), or Wheelock's Power Supplies. The Strobes use a Xenon flashtube with
solid state circuitry enclosed in a rugged Lexan® lens to provide maximum visibility and reliability for effective visible signaling.
