27.3 Walk test mode – transmission test – installation help
This function is used to support installation. It can help to verify that all detectors
are working correctly within the system and no alarm is transmitted at this test
function.
Walk Test Mode
P200E 6E
press
to start
This address is used to start walk-test mode while in installer or client program
mode. By pressing P200E 6E at the keypad, the keypad buzzer will beep at short
intervals to indicate walk-test mode is active.
By walking past all of the detectors connected to the system and activating them,
the associated zone will latch up at the keypad to allow verification that all zones
are working properly. Every time when a signal is triggered the display will indicate
the Zone number of the detected device and the keypad buzzer will give a short
double beep as confirmation while walk-test mode is active (If a siren is connected
to an output and that output has option 1 turned on at location P36E the siren will
give this confirmation as well).
Leaving the Walk test mode- Displaying results
By pressing the
Prog
or button, walk-test mode will be terminated and the panel
will leave program mode. The results of the walk-test will be saved in the memory
event buffer and can be viewed by accessing memory display mode to verify which
detectors were triggered during walk-test mode. If output 1 or 2 are used for the
audible walk-test indication and a horn speaker is connected to the output (see
chapter
16.1: Output options; Output D Options, option 1; P37E 1 or 2E), the siren
on the output will give a single tone for the chirp instead of the swept tone used for
alarms.
Transmission test
Some detectors have the functionality of a transmission test (refer to the datasheet
of the detector). With this function it could be checked if all Test signals,
transmitted by the detectors are received at the control panel. This indicates the
quality of the range and position of the detectors to the control panel. If not all
signals are received by the control panel you might use a second receiver
IRFW6-10 or change the position of the detector.
During Walk Test Mode the control panel receiver attenuate the incoming Signal by about
6 dB which is a requirement of the EN 50131. The meaning behind is, due to the fact that there may
be changes in the passive environment after installation it should be possible to receive a much lower
RF signal to ensure if the signal is getting disturbed the control panel will still be reached. This might
lead to a different wireless distance range where the detector is working good or bad according to
normal mode or walk test mode.
