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.
In case of failure or power cut, a 5-hour battery backup is activated. This function is operated by a 9V battery.
For ventilation plants with variable speed, a voltage relay is available.
The pressure switch must be ordered separately.
