IFS-2600 Fire Indicator Panel Section 3 Operation
DOC-01-009 10
For the duration of walk test mode, all zones are changed to output configuration #2 (indicate and ring
bells only) and all zones are set to type #1 (standard latching, 2 second).
If the bells are not required to ring during walk test, simply press the "EXT BELL ISOLATE" key once. The
EXT BELL ISOLATE LED will illuminate to verify that the bells have been isolated.
Any alarm signal from detectors will be received by the panel on its appropriate zone. The panel will
beep to acknowledge receipt of the alarm and indicate the alarm by illuminating the appropriate alarm
LED for 4 seconds (the bells will also ring for a 3 second period unless previously isolated).
The zone and detector will then be automatically reset for 15 seconds.
If the optional printer is connected, the alarm will be printed out as it is received. This can eliminate the
need for a second serviceman to record zone numbers during walk test and the printout can be retained
for verification at a later date.
Pressing any key will terminate the walk test mode and return the panel back to normal operation,
restoring all zone types and output configurations also ensuring that bell and ancillary outputs are de-
isolated. The bells will give three pulses of 1 second each to warn any testers still in the building that walk
test mode has been terminated.
Failure to receive any alarms or keystrokes within a 15 minutes period will result in the panel
automatically exiting walk test mode and returning back to normal as follows:
1. Bell outputs to be de-isolated.
2. Ancillary outputs to be de-isolated.
3. Bell will sound 3 times, each of 1-second duration.
4. Exit from walk test mode.
5. Zone types and output configurations restored
ACF ISOLATE
ACF
ISOL
Pressing the "ACF ISOLATE" key will isolate the ACF (Ancillary output) and the Door Holder Output. The
ACF isolated LED will illuminate and the output will not operate until de-isolated. Pressing "ACF
ISOLATE" for a second time will de-isolate the output.
If the ancillary output has already been tripped and is programmed as latching, isolating the ACF will not
affect the existing ancillary output. If the ACF is isolated prior to the alarm, it will prevent the ancillary
output from tripping. This does not apply to the Door Holder output.
ACF RESET
ACF
RESET
Resetting of the ancillary output (ACF) is only required if the ancillary output was programmed as
latching.
The ancillary alarm will remain latched until manually reset. Pressing the "ACF RESET" button will
extinguish the 'ACF Activated' LED and de-energise the ancillary output. Pressing "ACF RESET" when
the ACF is not tripped will have no effect.
