708-534-4756.
Introduction to the Model AV1-LED
The Model AV1-LED combination audible/visual signal features a
100-percent polycarbonate housing that is rated for Type 3R rain-
tight applications. The Fresnel lens provides superior visibility in all
directions. Available lens colors include amber, blue, clear, green, and
red. Jumper settings enable you to select a fast or slow ash rate and
whether the buzzer and/or LED operate intermittently or continuously.
The AV1-LED design provides three mounting congurations. The
black base will accommodate mounting to a 1/2-inch NPT pipe, a
4-inch octagonal electrical box, or any at surface. The surface-mount
gasket serves as a template for preparing a at surface with appropriate
mounting holes.
All Model AV1-LED units feature a unique twist-and-lock lens to enable
tool-free access to the LED light. The integrated buzzer provides 85 dB
output at 10 ft (95 dB at 1 m). Two voltage variations are available:
24 Vdc and 120 Vac. Each Model AV1-LED is factory-assembled with
two color-coded leads for wiring to a junction box. If necessary, installers
can remove the leads and connect the power supply to the Model AV1-
LED directly to the terminal block located in the base of the unit.
Mounting the Model AV1-LED
This section describes how to pipe-mount and surface-mount the light. To
mount the light on a vertical surface, use a separately purchased Model
LWMB2 (wall mounting bracket) or LCMB2 (corner mounting bracket)
mounting kit (Table 1 on page 18). For weatherproof installation, the
light must be mounted vertically with the lens facing upwards.
