Federal Signal AV1ST Data Sheet
Model AV1ST
Strobe Combination
Audible/Visual Signal
Model AV1ST is a combination audible/visual signal. The AV1ST features a 100% polycarbonate housing that is rated for
Type 3R rain-tight applications.
The AV1ST design provides three mounting configurations: 1/2-inch NPT pipe, a 4-inch octagonal electrical box or any flat
surface. All AV1ST units feature a twist and lock lens design to allow for tool free access to the strobe tube. The fresnel
lens provides superior visibility in all directions.
The integrated buzzer provides 85 dBa output @ 10 feet (95 dBa @ 1m).
The AV1ST comes in two voltage variations: 24VDC and 120VAC. Each unit is factory assembled with two color-coded
leads. If desired, the user can remove the leads and connect directly to the terminal block located in the base of the unit.
