Alarms
The alarms are output via relay contacts and red LED.
Alarm settings
sensor channel I and II
Each sensor channel has one alarm 1 and alarm 2, which can
each be assigned different switching thresholds within the
measuring range.
You can set a delay time of 0 – 120 min for each alarm.
Each alarm can be defined as:
• N.O. contact (normal status = opened)
• N.C. contact (normal status = closed)
• unlatched
• latched with confirmation
See 4.3.1 “Alarm modes" on page 26.
Door contact input
A door contact input is integrated for each sensor channel.
For example, to switch off the sprinkler system when the gas room
doors are opened (see 4.5 “Door contact switch" on page 32).
When a door contact switch is used, local safety regulations must
be observed.
Sensor alarm
The sensor alarm is designed as a common alarm. The sensor
inputs can be freely assigned.
Multiple assignment is possible on:
• Sensor I
• Sensor II
• Temperature I
• Temperature II
If the defined sensor input signals are exceeded in either
direction(wire break, sensor error, etc.), the sensor alarm is
activated if this sensor is assigned to the sensor alarm.
You can select an ON delay of 0 – 5 min.
For Chloratect sensor, µA signal < 0.1 µA.
For mA-Sensor, mA signal < 4 mA.
