9 System performance check
The operation and checking of indicators must be take place at the control unit
terminal (Main terminal).
Modes for detector test
Two different modes can be chosen:
1. Detector test mode
– Alarm devices and control functions are disabled.
– If the detector responds, it signals, "Test activation" for about 10 seconds with
alarm indicator blinking.
2. Installation test mode
– All control unit functions work normally; alarm devices and control functions
are enabled.
– If the detector responds, it activates ALARM, the alarm indicator flashes.
ALARM must be operated in the normal way.
For both test modes, in order to speed up the response time, the detectors them-
selves are switched to a special test mode bypassing the signal processing algo-
rithms.

9.1 Schedule for the performance check
Detector self-test
Through the detector self-test the detectors are subjected automatically to an ex-
tensive electrical function check. However, it is still necessary to conduct a physical
function test on site in regular intervals.
Recommendation
A visual check of the detectors must be performed once per year. Detectors that
are strongly soiled or which are mechanically damaged must be replaced. Check
the system for changes of use.
Intervals
We recommended the following schedule for the performance check. However, lo-
cal national regulations have priority.
Interval in years
1 2 5
SW clock Check of date and time.
Check each line by means of detector activation and verify
display.
Activate all automatic fire detectors (can be done by cus-
tomer).
Activate 1 manual call point for each line.
Activate all manual call points.
Check detectors visually for soiling and proper application.
With each line, check whether short-circuit or open line (re-
move detector) activates a FAULT signal.
Detection lines
collective
Overhaul at the factory of all automatic fire detectors. See chapter 9.2
Activate 1 automatic detector and 1 manual call point for each
line.
Activate all automatic fire detectors.
Activate all manual call points.
Activate "Reconfigure D-Bus" for all lines.
Check detectors visually for soiling and proper application.
Check of the function of I/O modules (DC1192, EB, AB, ABI).
Check for each line whether a short circuit / open line acti-
vates a FAULT signal.
Check the loop line function.
During the short circuit also check the isolator function.
