l
temperature and humidity sensors) can be supported.
2.6.2 Alarm Indicator
The 10 red indicator on the alarm box panel correspond to the following alarm
values:
Fire alarm: alarm generated due to over heat or by smoke detector.
l
Smoke alarm: overtime alarm generated by the smoke sensor.
l
Temperature upper limit: alarm generated when the ambient temperature
l
exceeds the upper limit.
Temperature lower limit: alarm generated when the ambient temperature
l
exceeds the lower limit.
Humidity alarm: alarm generated when the relative humidity is not in the
l
specified range.
Soaking: alarm generated when the soaking detector is triggered.
l
Air-conditioner
l
air-conditioner.
Optical/electrical: burglar alarm generated when the optical/electrical switch is
l
triggered.
Infrared: burglar alarm generated when the infrared sensor is triggered.
l
Door magnetic: generated burglar alarm generated when the door magnetic
l
switch is triggered.
When there are more than one input signals from the same type of sensors, they will
be regarded an alarm event. Maximally 10 sensors of the same type (except the
temperature and humidity sensors) can be equipped.
