Walk Test™ is a software-based function and is programmed to meet the customer
requirements. The system will pulse the signals for alarm conditions, then reset. The signals
will sound steady for 4 seconds to indicate fault conditions, then reset. A silent Walk Test™
may be performed (no signals will sound) and logging of events may be selected.
The auto reset/auto acknowledge operation allows for one-man testing without the need for
someone at the main control panel to acknowledge and reset the system. The Walk Test™
mode also bypasses many of the delays that are inherent to the normal reset procedure, thereby
allowing for a faster test. The automatic reset ( 5 second power drop) only occurs on the zone
that comes in after a configurable time delay (default = 15 seconds). This delay can be
optimally set (with the programming unit) for the time it should take for a zone to clear (i.e.
magnet vs smoke tester).
If an alarm condition is detected from a zone that is not in the present active Walk Test™
group, the system will operate as a fire alarm panel and the active Walk Test™ groups are
aborted. The system has an automatic abort or timeout for the Walk Test™ mode. If no zone
within the active Walk Test™ group is activated within 8 hours, the system will abort the
Walk Test™ mode and return to normal.
The 4100U-S1 will support up to eight Walk Test™ groups. This allows the building to be
divided into small portions for the Walk Test™, and allows the rest of the building to be
protected by the fire alarm panel. Each group has a list of output circuits which activate when
selected.
If you select the Walk Test™ by group mode, a system fault will be reported to remind you
that the Walk Test™ is enabled.
Whenever a Walk Test™ group is aborted, manually or automatically, the panel will sound
the abort signal (three sets of two short pulses) to indicate that group is going back into
service. If a control point in the list is already active (because of an abnormal condition), it is
not used to signal the abort.
The group is placed into normal operation 60 seconds after the abort signal is heard. This
delay protects against an unwanted alarm should an automatic abort occur while a device is
being tested.
The system is default-programmed to allow the Walk Test™ to be performed without
sounding audible signals. (See “Silent Walk Test™” and “Sig/No Sig”.) The Walk Test™
will not activate any point which is disabled. Therefore, you have the ability to manually
exclude any point from the test. (See How to Disable a Point.)
You may enable the logging of Walk Test™ events, which allows each zone with an abnormal
condition to be time tagged and added to the fault log. This is beneficial when a 100% silent
Walk Test™, without visuals, is required. When testing the devices, use the alarm LED on
the smoke detector, or a simple delay, to know when to continue to the next device. After test
completion, check the log to verify that all zones activated the correct number of times and in
the correct order.
The system supports two types of audible signalling to indicate an alarm condition on a zone.
By default, “zone coding” is used. This code matches the “ZONE” number associated with
that point. The zone code is only used the first time a zone is reported. For subsequent alarms
on the same zone, a single “0 CODE” (two short pulses) is used. Examples of Zone Coding
are shown below.
