Federal Signal introduces the Model AV1ST combination audible/visual signal. The AV1ST features a 100% polycarbonate housing that is rated for Type 3R rain–tight applications. Available dome colors include amber, blue, clear, green and red.

The AV1ST design provides three mounting configurations. The black base will accommodate mounting to a 1/2–inch NPT pipe, a 4–inch octagonal electrical box or any flat surface. The surface mount gasket serves as a template for preparing a flat surface with appropriate mounting holes.

All AV1ST units feature a unique twist and lock dome to allow for tool free access to the strobe tube. The fresnel lensing provides superior visibility in all directions.

The integrated buzzer provides 85dB output at 10 feet (95dB @ 1 meter).

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. The AV1ST is UL and cUL Listed; CSA Certified.
