S-Quad Exceptions or Condition codes
The Exception codes are also sometimes called condition codes and these codes provide information about a sensor device. A code
indicates small changes in the:
¨
environmental condition
¨
sensor mechanism and
¨
how the sensor performs in the system.
"
To ensure that the sensor exception codes are meaningful, after power up the system should be left
undisturbed for at least 24 hours.
Definition
There are ten different conditions possible for each sensor type, although not all of them are defined. Each condition code has a
range of 0-3,
Exception/

3
The sensor is faulty. A fault condition indication is given at the control panel. A message
reading 'Sensor Out of Specification' is displayed.
"
A sensor having code 3 is automatically disabled by the system to prevent false alarms.
