Technical data
Device variant TFM-1
With integrated measurement of the actual volume flow value being monitored via an installed effective pressure measuring device using an effective pressure measuring lance
Scope of supply
Device variant TFM-2
With an analogue 0-10 V input for the recording of the actual volume flow value, e.g. from the output of a VAV controller
Scope of supply
- 2 independent volume flow monitoring values with upper and lower limits
- Deactivation of the monitoring function either as break contact or make contact
- Sash window monitoring > 500 mm with optical/acoustic alarm
- Alarm signalling can be configured:
Trigger delay, duration of acoustic alarm, alarm transmission per relay - Signalling in case of supply voltage failure
- Supply voltage 24 V AC/DC
