Selecting this option provides all the interrogation and control functions. All output functions are disabled and only the chosen device is being polled. This allows sensor devices to be put into the test mode without alarms, etc. being raised and allows observation of the rising analogue value.

Selection of this option causes the control panel to output status information for all connected devices to its printer (if fitted).
Selecting this option enables specified
devices to be interrogated and for commands to be sent to the devices. When the self test mode is entered in this condition, the device under test should eventually enter an alarm condition. When this occurs the control panel will react as if a genuine alarm condition had been detected. The system will exit the engineer’s test mode and will need to be silenced and reset in the normal manner.
5.8.1Status Disabled/Enabled
Selecting Status options 1 or 2 will allow the engineer to enter the loop and device numbers. The display then shows the following:
ADR VAL TYPE STS CMD
10023 ION 000 000 ZONE 12 CMD BITS=123 4)PREV 5)NEXT #)END
The typical display example shown above is interpreted as follows:
The device address (ADR) is 100
The analogue value (VAL) is 23
The device type (TYPE) is ionisation smoke (ION)
The input status (STS) is 000
The control panel command status (CMD) is 000
The allocated zone for the device is 12
Key 4 allows the user to move to the previous device. The above example will be decreased to address 99.
Key 5 allows the user to advance the address of the device being interrogated. The above example will be advanced to address 101.
Key # to escape.
