Supervisory Conditions
Walk Test
System Testing (Fire Drills)
A Fire/Supervisory point distinguishes between Fire Alarm and Supervisory
conditions on a single circuit. When water is flowing in a sprinkler system, an
Alarm is indicated, but if a sprinkler or water pump valve has been closed, a
"SUPERVISORY" service condition is indicated. This condition is distinctly
different from a trouble or alarm condition. The yellow "SUPERVISORY"
LED flashes and the tone-alert sounds until the condition is acknowledged via
the "ACK" key. After pressing the "ACK" key, the "SUPERVISORY" LED is
ON steady, unless the user is scrolling (Supervisory is second priority). The
supervisory state is only available on points configured as Fire/Supervisory type.
The 4004 is equipped with Walk Test, this feature allows one person to test the
4004 System. Walk Test is activated using the dedicated switch (SW4 on the
System Board). The following conditions apply during Walk Test operation.
•
Alarm - An alarm from an IDC is indicated with zone code notification
over both NACs. If NACs are connected to strobes, the strobes may
not indicate the zone code.
•
Trouble - A trouble from any IDC, NAC, or an Earth Fault is indicated
by activating NACs for four seconds.
•
Walk Test switch is ignored if there is an alarm in the system.
•
An upper case "H" on the yellow "TROUBLE" display indicates Walk
Test trouble.
•
City Circuit activation is not inhibited during Walk Test, it must be
disconnected via the Disconnect Switches on the card.
•
Display and tone-alert function as they would under normal conditions.
•
Automatic system reset occurs within 30 seconds after Walk Test alarm.
•
Subsequent alarms on the same zone causes another zone code (not a
zero code).
•
A "SYSTEM RESET" is done when exiting from Walk Test. Any
zones still in an alarm condition initiate an alarm after the system reset.
Fire Drills must be conducted periodically to ensure that the building occupants
are familiar with emergency procedures and that all system equipment is
functioning properly and is in good condition. This testing should be done under
the direction of the owner and the local Authority Having Jurisdiction (AHJ).
System testing is initiated when the following considerations have been
determined:
•
How does the owner and AHJ want the drill or test performed?
•
Is the building occupied?
•
Which system features are currently in use?
If a building is not occupied and no city connection or DACT are used, there is
less concern that confusion will result from testing the system. Systems
connected to a city circuit must notify the local AHJ. The AHJ determines if the
city connection should be disabled during the test.
