Audible Walktest

Walktest

Operating Instructions

4.1.5 Walktest

The Walktest button, which is located on the FACP membrane switch panel, allows a panel walktest to be performed. Pressing and holding the Walktest button for a minimum of two seconds causes the FACP to enter audible walktest. Pressing the Walktest button and then the Silence button and holding both for a minimum of two seconds will cause the panel to enter silent walktest. Walktest can be exited by pressing and holding the Walktest button for a minimum of three seconds or by pressing the Reset button. Refer to “Walktest” for a complete description of this feature.

4.2 Walktest

Walktest allows the testing of all control panel IDCs (input zones). An audible or silent walktest may be performed.

It is important to note that while the FACP is in Walktest mode, the control panel is in an off-normal condition and does not provide fire protection.

It should also be noted that the trouble relay will be activated while the control panel is in Walktest mode. Placing the control panel into Walktest mode will only be possible if the system has no active alarms.

Prior to initiating a walktest, check to make certain that all system faults have been cleared. Upon entering Walktest mode, the following conditions should occur:

•Trouble relay will activate

•Alarm relay will be disabled

•Supervision relay will be disabled (MS-4 only)

•Piezo sounder will be disabled

•I3 smoke detectors will enter their own test mode causing their LEDs to flash twice every five seconds (refer to the I3 specification document)

•All alarm conditions will be displayed as they occur by blinking zone alarm LED

•All zone troubles will be displayed as they occur by blinking zone trouble LED

During walktest, the FACP zone LEDs will blink for the first activation on a zone. Subsequent activations on the same zone will cause the corresponding zone LED to blink the number of alarms on the zone since the start of the test, followed by a two second pause and then a repeat of the sequence.

Note that following a zone activation, a 6 second reset for conventional and 60 second reset for I3 detectors is initiated. No new alarms or troubles will be detected during this reset period.

Disabled zones will not respond during Walktest. A zone may be disabled while in Walktest mode, should a faulty device be detected. This allows the user to return the system to Normal mode, enabling all other zones while preventing the faulty zone from triggering a false alarm.

To perform an audible Walktest, press and hold the Walktest button for a minimum of two seconds. The Trouble and Walktest LEDs will blink at a ¼ second rate.

While testing input devices, the first initiating device activated on a zone will cause the NACs to sound for four seconds. Subsequent device activations on the same zone will cause the NACs to turn on for one second. Any smoke detectors that are activated will automatically be reset by the panel. Zone faults (open circuits) will cause the NACs to remain on steadily until the fault is cleared.

During an audible walktest, if a device remains latched in alarm (such as a Pull Station that is not reset after activation), subsequent testing of devices on the same zone will not trigger the NACs. Be certain to reset or clear each device after testing.
