P1 Relay:
Option of setting a delay time for the operation of an additional negative pressure machine and/or alarm lamp with
horn via an external relay block.
Please note!
A relay block only works for values measured using measuring point P1-.
An external relay allows you to turn an additional negative pressure machine and/or flashing light with horn for
acoustic and visual alarms on or off, with due observance of the set delay time and the set measuring limits (A, B, C, D,
or E, in terms of both negative and positive pressure).
As soon as the set lower limit is no longer being reached, the external relay will automatically be activated, with due
observance of the set delay time. This will then activate the back-up negative pressure machine and cause the alarm
lamp with horn to provide an acoustic and visual alarm. The external relay block will automatically be turned off once
the upper measurement limit has been reached.
