The FA350WY is a general purpose LED visual indicator for alarm applications. It a special base containing all wiring connections and allows for easy removal/placement of the device and base. The FA350WY allows faster installation and maintenance thanks to an innovative mounting base. Dispensing with the need for locking screws, these devices use TimeSave bases from the 630 series detectors. Heads are simply locked onto the base with a twist and click action, allowing fitting or removal at any time because the base is the only component that needs to be wired. As the cabling requirement is reduced, commissioning time and costs are naturally reduced as well. A mechanism for locking the devices to the base may be activated if required. Once activated, a special tool is required to remove the device from the base. The FA350WY utilises a full faced translucent case, giving a much larger lens area and a greater spread of light.
