Amseco’s SelectAStrobe Series is designed to comply with the Americans with Disabilities Act (ADA) and meet UL standard 1971 requirements for emergency signaling devices for the hearing impaired. The SelectAStrobe SL24W series features a unique candela intensity field selector switch for alternating the candela output 75cd to 110cd. The strobe housing is clearly labeled with vertical “FIRE” lettering. The strobe is polarized for connecting to supervised fire alarm circuits and is designed with a xenon flashtube to provide maximum performance with a candela intensity field selector switch. The SL24W-75110 can be synchronized by using the SMD10-3A Sync Module to comply with NFPA recommendations concerning photosensitive epilepsy when installing two or more visual appliances within the field of view. The strobe signals are listed for indoor use, wall mount, under UL 1971 standard.

Engineering Specifications

The visual alarm indicating appliance shall be Amseco model SL24W-75110 or equivalent device. The strobe shall be listed under UL 1971 standard for signaling devices for the hearing impaired and shall be approved for fire protective service. For outdoor applications and in UL NEMA-4X rated or UL Haz Dust Tight condition, use Amseco UL/ULC ESH1229/1229HTR polycarbonate covers. The candela output shall be field selectable, having a dual setting of 75cd or 110cd output. The signaling strobe shall operate on 24V DC from a noncoded regulated DC supply or fullwave rectified, unfiltered supply. The strobe shall be designed to produce one signal flash per second with continuously applied minimum voltage. The strobe shall have a universal back mounting plate, capable of wall mounting to a back box. When strobe synchronization is required, the strobe shall be compatible with Amseco SMD10-3A (daisy chain) or other source of Amseco sync protocol. Visual signaling devices shall be installed in accordance with current NFPA guidelines.

WARNING
Strobes must be used only on circuits with continuously operating voltage. DO NOT use strobe on coded or interrupted circuits in which the applied voltage is interrupted ON and OFF as the strobe may fail to flash. The applied voltage must be within its rated input voltage range. Fuse ratings on signaling circuits must handle peak currents from all devices connected to those circuits.
