INSTALLATION INSTRUCTIONS
SERIES ET70WP LOW PROFILE WEATHERPROOF SPEAKER STROBE APPLIANCE
Use this product according to this instruction manual. Please keep this instruction manual for future reference.
GENERAL:
Cooper Wheelock’s Series ET70WP Low Profile Speaker Strobe appliance is UL Listed for indoor/outdoor use under Standard 1638 and Standard 1971 for Visual
Signal Appliances, Fire Protective Service and UL Standard 1480 for Speaker Appliances. For outdoor applications the ET70WP must be 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 power supplies. The strobes use a xenon flashtube with solid state circuitry enclosed in
a polycarbonate lens to provide maximum visibility and reliability for effective visible signaling.
WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY. FAILURE TO COMPLY WITH ANY OF THE FOLLOWING
INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION, INSTALLATION AND/OR OPERATION OF
THESE PRODUCTS IN AN EMERGENCY SITUATION, WHICH COULD RESULT IN PROPERTY DAMAGE AND SERIOUS INJURY OR DEATH TO
YOU AND/OR OTHERS.
CAUTION: NOT RECOMMENDED FOR USE AT REFRIGERATOR / FREEZER DOOR ENTRANCES OR OTHER AREAS WITH PERSISTENT

NOTES:
1. Strobes will produce 1 flash per second over the "Regulated Voltage" range.
2. All models are listed for indoor and outdoor use. UL 1971 is tested from a temperature range of 32ºF to 120ºF (0ºC to 49ºC). UL 1638 is tested from a
temperature range of -40ºF to +150ºF (-40ºC to +66ºC) with a maximum humidity of 95% RH. The effect of shipping and storage temperatures shall not
adversely affect the performance of the appliances when it is stored in the original cartons and is not subjected to misuse or abuse.
3. The maximum supervision voltage is 33 volts DC.
4. Frequency range of speakers is 400-4000Hz. dBA is rated per UL Standard 1480 for Speaker Appliances.
CAUTION: Always operate audio amplifiers and speakers within their specified ratings. Excessive input may distort sound quality and may damage audio
equipment. Do not exceed 100% of speaker input voltage per UL 1480. Improper input voltage can damage speaker. If distortion is heard, check for clipping of the
audio appliance with an oscilloscope and reduce the amplifier input level or gain level to eliminate any clipping.
Table 2: Strobe Current Ratings (AMPS)
Maximum RMS Current
UL Voltage 2475 24115 24135 24177 24185
DC 16-33VDC 0.138 0.300 0.300 0.420 0.420
FWR 16-33VRMS 0.222 0.455 0.455 0.645 0.645
When calculating the total currents use Table 2 to determine the highest value of RMS current for an individual strobe, then multiply these values by the total number of
strobes. Be sure to add the currents for any other appliances, including audible signaling appliances powered by the same source, and to include any required safety
factors.
NOTE: The maximum number of strobes on a single notification appliance circuit shall not exceed 50.
