4906-9132 Simplex, Weatherproof multi-candela TrueAlert appliances provide VO and AV SmartSync operation for indoor and outdoor, extended temperature and extended humidity applications. The enclosures are impact and vandal resistant and provide a convenient strobe intensity selection. Because each model can be selected for intensity output, on-site model inventory is minimized and changes encountered during construction are easily accommodated. Operation details: A visible intensity selection jumper is secured behind the strobe housing. Polarized input allows connection to compatible reverse polarity, supervised notification appliance circuit (NAC). Regulated circuit design ensures consistent flash output and provides controlled inrush current. AV appliances have an efficient electronic horn Strobe intensity selection During installation, use the selection plug at the back of the housing to determine the strobe intensity. Use the attached flag with black letters on a yellow background to see the selected intensity at the side of the strobe lens. Strobe application reference Correct selection of weatherproof notification is dependent on occupancy, location, local codes, and correct applications of: the National Fire Alarm and Signaling Code (NFPA 72), ANSI A117.1; the appropriate model building code: BOCA, ICBO, or SBCCI; and the application guidelines of the Americans with Disabilities Act (ADA). Requirements may differ from indoor appliance applications, contact your local authority having jurisdiction (AHJ) to assist in determining requirements. 4906-9132.See all our parts for  .
