Long Branch, NJ 07740 (800) 631-2148 INSTALLATION INSTRUCTIONS www.wheelockinc.com SERIES ET90-24MCCH MULTI-HIGH CANDELA SPEAKER STROBE Use this product according to this instruction manual. Please keep this instruction manual for future reference. GENERAL: Wheelock’s Series ET90-24MCCH Multi-High-Candela Low Profile Speaker Strobe is UL Listed under Standard 1971 for (Signaling Devices for the Hearing Impaired) for indoor fire protection service. The ET90-24MCCH is designed for multiple power requirements with high dBA output at each power tap and offer 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 ET90-24MCCH Multi-High-Candela provides two selectable light output intensities in one unit and incorporates a speaker mounting plate attached to the speaker for ease of installation. The Low Profile Speaker Strobe 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 strobe uses a xenon flashtube with solid state circuitry enclosed in a polycarbonate lens to provide maximum visibility and reliability for effective visible signaling. The ET90-24MCCH is Listed for indoor use, ceiling mount only with the backboxes specified in these instructions (see wiring and mounting information). WARNING: PLEASE READ THESE INSTRUCTIONS CAREFULLY BEFORE USING THIS PRODUCT. FAILURE TO COMPLY WITH ANY OF THE FOLLOWING INSTRUCTIONS, CAUTIONS AND WARNINGS COULD RESULT IN IMPROPER APPLICATION, CANDELA SETTING, 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.

The strobe will produce 1 flash per second over the "Regulated Voltage" range. 2. Strobes meet the required light distribution patterns defined in UL 1971. 3. The ET90-24MCCH is UL Listed for indoor use with a temperature range of +32°F to +120°F (0°C to +49°C) and maximum humidity of 85% RH. The effect of shipping and storage temperatures shall not adversely affect the performance of the appliance when it is stored in the original cartons and is not subjected to misuse or abuse. 4. The maximum supervision voltage is 33 volts DC. 5. Frequency range of speakers is 400-4000Hz. 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. WARNING: CANDELA SETTING WILL DETERMINE THE CURRENT DRAW OF THE PRODUCT. Table 2: UL Current Ratings with Strobe Only Maximum RMS Current (Amps) UL Voltage 115cd 177cd DC 16-33VDC 0.300 0.420 FWR 16-33VRMS 0.455 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. CAUTION: These strobes are UL Listed as “Regulated”. They are intended to be used with FACPs whose notification circuits are UL Listed as “Regulated.” These appliances shall not be used on UL Listed “Special Application” notification circuits unless the appliances are identified to be compatible in the installation instructions of the FACP or unless the FACP is identified to be compatible in this instruction manual. WARNING: THESE STROBES WERE TESTED TO THE REGULATED VOLTAGE LIMITS OF 16.0-33.0 VOLTS FOR 24V MODELS USING FILTERED DC OR UNFILTERED FULL-WAVE-RECTIFIED VOLTAGE. DO NOT APPLY VOLTAGE OUTSIDE OF THIS RANGE. WARNING: CHECK THE MINIMUM AND MAXIMUM OUTPUT OF THE POWER SUPPLY AND STANDBY BATTERY AND SUBTRACT THE VOLTAGE DROP FROM THE CIRCUIT WIRING RESISTANCE TO DETERMINE THE APPPLIED VOLTAGE TO THE STROBES. THE MAXIMUM WIRE IMPEDANCE BETWEEN STROBES SHALL NOT EXCEED 35 OHMS. CAUTION: Strobes are not designed to be used on coded systems in which the applied voltage is cycled on and off.
