The ANSUL Water Oscillating Monitor is a mechanical device designed for fire suppression, specifically for use with ANSUL WOM-3 and WOM-4 models. It is intended for those who install, operate, maintain, or service these monitors. The device requires periodic care, with maintenance recommended every six months or more frequently if desired, to ensure effective operation. Discharge testing should be conducted at intervals in accordance with end-user policies or the authority having jurisdiction, whichever is stricter.
The Water Oscillating Monitor is designed to discharge water or foam in an oscillating pattern for fire suppression. It features an oscillating mechanism that allows the monitor to sweep a specified arc, providing broad coverage. The monitor's elevation can also be adjusted to direct the stream effectively. It can operate in both automatic oscillation mode and manual operation mode. In automatic mode, the monitor oscillates automatically at set limits when the main water supply is turned on. In manual mode, the oscillating mechanism can be disengaged, allowing the monitor to be rotated manually using a tiller bar (WOM-3) or handwheel (WOM-4) and its elevation adjusted.
