Product is discontinued.

Bundle with Ventilation Alarm ES 332 230V and pressure switch Huba HC604 500-2000Pa.

Ventilation Alarm E is designed as a help to ensure correct operation of the ventilation plant.

A typical application could be a plant in which the pressure is to be controlled 4 meter up, just under the ceiling. In this case the pressure switch is installed on the ventilation duct and the control board is mounted in a position visible to the user.

The pressure alarm is able to monitor pressure in a local exhaust ventilation unit or centrally in a ventilation plant. If the pressure drops resulting in poor ventilation, the pressure alarm activates an alarm in the form of a red flashing light and a beeping sound. Furthermore, a relay output is shifted. The audible alarm can be muted on the box front. Output for connection of external alarm lamp is available.

Including a Pressure Switch with integrated change over switch, low hysteresis and positive and negative pressure connection. Intended for use in ventilation ducts for control of filters and ventilators and/or for control of damper. To be used with non-corroding air and gasses. 500-2000Pa

In case of failure or power cut, a 5-hour battery backup is activated. This function is operated by a 9V battery.
