Options for your Applications
The WA400-DC battery powered version may be quickly deployed in temporary emergency applications or anywhere you need a level alarm where no AC power is available. The unit will strobe and sound for up to 12 hours on its eight standard 1.5 volt AA batteries.
The WA400-AC externally powered version allows you to the use the alarm with water level sensors, any standard float switch, or any contact closure. Our WA400-BU version includes an automatic battery backup in addition to standard AC power a great feature if your AC power source may be unreliable.
Augment with Accessories
Our rugged WA600 Water Alarm Sensors provide high and low water level detection capabilities for the WA400-AC unit. (Please note that the WA600 sensor should not be used with the WA400-DC model.) Our specially designed WA100 liquid level float switch is compact and selfweighted for quick and easy installation, and it works on any of the WA400 units. Also, the WA100 may be configured for NO (normally open) high level actuation or NC (normally closed) low level actuation.
The WA400 Level Alarms may also be used on other equipment such as our PC300 controller, or any device that has a dry contact switch output including samplers, pump panels, and security switches.
