Cooper Wheelock Horn Strobe- Series AMT Multitone
Wheelock Fire Horns & Strobes
Cooper-Wheelock Alarm Horn Strobe
Cooper-Wheelock’S Series AMT Multiple Input Electronic Appliances provide the industry with a UL Standard 1971 and UL Standard 464 combination audible/visual device that simplifies installation and offers three (3) distinct prioritized audible signals from three isolated inputs. Priority (1) will override all other commands upon activation.
The AMT offers a choice of eight (8) self-prioritized sound combinations for suppression releasing systems, combination security and emergency evacuation systems and high risk installations as well as many other applications.
The AMT Fire Horn Strobes are designed for ADA applications with maximum performance, reliability and cost-effectiveness while meeting or exceeding the latest requirements of NFPA 72 (the National Fire Alarm Code), ANSI 117.1 (the American National Standard For Accessible and Usable Buildings and Facilities) and UL Standard 1971 (Standard for Signaling Devices for the Hearing Impaired). AMT Strobes, when properly specified and installed in accordance with NFPA/ANSI Standards, can provide the Equivalent Facilitation allowed under ADA Accessibility Guidelines (ADAAG General Section 2.2) by meeting or exceeding the illumination which results from the ADA specified strobe intensity of 75 candela at 50 feet. This is an illumination of 0.030 lumens per square foot (footcandles).
Each AMT Audible and AMT Strobe appliance has two user selective sound output levels: STANDARD dBA and HIGH dBA. The AMT Audible provides 12VDC or 24VDC operation, filtered or FWR. The AMT Strobe Electronic Appliances operate at 24VDC and may be used with filtered or unfiltered (full-wave-rectified) input voltages. Separate supervised sets of input terminals are available for each prioritized input. Jumper plugs are provided to enable both tone and strobe to operate simultaneously for all inputs.
The AMT Multitone Strobe fire notification devices are UL Listed for indoor use, wall mount, under Standard 1971 for Signaling Devices for the Hearing Impaired and Standard 464 for Audible Signal Appliances, and use a Xenon flashtube with solid state circuitry enclosed in a rugged Lexan® lens to provide maximum reliability for effective visible signaling. Models rated 1575 candela are Listed at 15 candela under UL 1971 and meet 75 candela intensity on axis for ADA guidelines with low current draw.
