Description:
Selectable Candela Output:
Potter's Select-a-Strobe series are designed to comply with the
Americans with Disability Act (ADA) and meet UL standard 1971
requirements for emergency signaling devices for the hearing
impaired. The AS-24 series Select-A-Strobe features a unique
candela intensity field selector switch for switching the candela
output from 75 or 110 cd. The strobe is polarized for connecting
to supervised fire alarm circuits and is designed with a xenon
flashtube. The strobe provides a candela intensity tamper-proof
field selector switch for maximum performance.
The AS24-75110R Select-A-Strobe can be synchronized by
using the SM-3A sync module to comply with NFPA recommendations concerning photosensitive epilepsy when installing 2 or
more visual appliances within the field of view. The strobe signals
are listed for indoor use, wall mount, under UL 1971 standard.
Tamper Proof
Application:
The AS24-75110R series strobes are recommended for use in
areas such as; meeting rooms, schools, corridors, apartments,
office buildings, restaurants, hotels, and any other application
where effective visual warning is required by Federal, State, or
local authority having jurisdiction.

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 strobe 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.
