Lumina 38
Basic principle thermo differential
52
An extreme rise in house temperature can be caused by fire. In such a case, it is important that an alarm is raised
quickly. The sensors (assigned to the house temperature) in the zones can detect sudden rises in temperature. A
sensor issues an alarm if:
•
It measures a temperature above 58°C;
•
The maximum temperature increase is exceeded (e.g. an increase of 5°C within 2 minutes).
The control computer monitors to that effect the current house temperature every 30 seconds and compares
it with the values of the last 2 minutes.
In addition to the alarm relay, the control computer has an extra relay to connect to the fire alarm installation
(FAI). In case of a fire alarm, this FAI relay then initiates additional actions such as closing fire doors, turning on
sprinklers or turning off ventilators.
To activate the thermo differential, the relay for the thermo differential must be assigned.
