General Information

The Model 531A Strobe features an incandescent lamp for constant-on operation and a high-intensity
xenon tube for flashing operation, with secondary contact for auxiliary equipment. The incandescent
lamp remains constantly on for area location while the xenon tube flashes on and off, 65 flashes per
minute, when activated by an emergency telephone.

The Model 531A Strobe is designed for top-of-pole mounting, wall mounting, or surface mounting.

The unit is equipped with a ¾-inch NPT female pipe thread in the base; a pipe nipple or conduit with a
corresponding thread should be used for mounting the units. For wall or surface mounting, the
GAI-Tronics Model 4115A Mounting Assembly Kit is recommended.

WARNING

Research indicates that a small portion of the general population,
(approximately 1 in 100,000) with Photosensitive Epilepsy (PSE) may experience
epileptiform seizures upon exposure to certain visual stimuli including lights flashing in
excess of 3 Hz (180 cpm). Individuals with positive photic response to visual stimuli who
are prone to seizures, such as persons with epilepsy, should avoid prolonged exposure to
environments in which flashing lights are activated.
