Federal Signal AV1-LED flashing combination AV signal
By Craig Pearson
Federal Signal’s Model AV1-LED combination audible/visual signal boasts a 100% polycarbonate housing rated for Type 3R raintight applications, as well as a 60,000-hour LED light source. Available in Amber, Blue, Green, Red and clear domes, the AV1-LED offers three mounting configurations; the unit’s black base is designed to accommodate mounting of 1/2-in. NPT pipe, a 4-in. octagonal electrical box, or any flat surface. (A surface-mount gasket serves as a template for mounting holes.) Key features include a twist-and-lock dome to facilitate tool-free access to the LED, while the integrated buzzer provides 85dB output at 10 ft (95dB at 1 m). The unit is capable of supplying independent flashing light and sounder operation. The LED can be field adjusted for a flash pattern of either 60 fpm or 75 fpm by employing a jumper on the PC board. Available in 24vDC and 120vAC, the UL- and cUL-listed AV1-LED is factory assembled with two colour-coded leads.
