Fire-Lite MS-10UD Series FACP - Manual (Page 104)

104 MS-5UD & MS-10UD Series Manual — P/N 52626:C4 3/7/2014
Operating Instructions Walktest
Note that if Trouble Reminder feature is not selected and the trouble is not cleared within 24 hours,
the piezo will resound, indicating that the trouble condition still exists.
4.17.4 Waterflow Retard Timer
If selected, this option will delay the activation of a waterflow type alarm for a programmable time
duration from 1 to 90 seconds. This delay is in addition to any time delay inherent in the waterflow
device. This feature requires the approval of the local Authority Having Jurisdiction.
4.17.5 Alarm Verification (None or One Minute)
If alarm verification is selected, a smoke detector activation will cause the FACP to reset the detec-
tor by removing power for 6 seconds. Power is reapplied and a 17 second retard period begins
which allows all detectors to stabilize. If no other detectors alarm, there will be no alarm indication
at the FACP during the 23 second Reset/Retard period. A Confirmation period of 60 seconds fol-
lows, during which a subsequent alarm from the same detector will cause the panel to immediately
activate the appropriate outputs and indicate the alarm condition at the FACP. If a different detector
zone alarms any time during the first detector's Retard & Confirmation period, the panel will imme-
diately activate all appropriate outputs and indicate the alarm condition at the FACP. If no addi-
tional detector alarms occur within 83 seconds of the first alarm (23 second Reset/Retard plus 60
second Confirmation), the timer resets and the panel is ready to verify any new detector alarms
which may occur.
4.18 Walktest
Walktest is a feature which allows one person to test the fire alarm system. An audible walktest
will momentarily sound the Notification Appliance Circuits in the building and store the walktest
information in a file at the panel. A silent walktest will not sound the NACs but will store the walk-
test information in a file which can be viewed at the panel. Disabled NAC devices will not activate
during walktest. In addition, i
3 smoke detectors will enter their own test mode causing their LEDs
to flash twice every five seconds (refer to i 3 specification document).
Alarm/Shorted Condition
When in audible Walktest, the panel responds to each new alarm and activates the NACs for four
seconds. It also stores each alarm in the walktest history file which can be sent to an optional
printer. The stored display will be the same as if the device actually activated except the colon (:)
in the time stamp is replaced with an asterisk (*).
NOTE: Alarm Verification is available only for smoke detectors.
