6.5 Walk test
The operator can use the WALK TEST feature to test the functionality of the control unit’s devices.
Press the WALK TEST key to activate the WALK TEST feature. This feature turns on the control unit piezo and the WALK TEST LED turns
steady on and the SYSTEM TROUBLE LED starts flashing.
To disable the WALK TEST feature, press the key again. The LED turns off, indicating that the walk test is disabled.
The walk test options are configured as follows:
• SIG: Enables the NAC for signal activation of an alarm or trouble condition. To enable WALK TEST in this mode, press the WALK TEST
key and to disable it press the WALK TEST key again.
• SIL: Disables the NACs so that the NACs do not sound during the walk test. To enable WALK TEST in this mode, press both the WALK
TEST and the SILENCE keys together and to disable it press both the WALK TEST and the SILENCE keys again.
When the control unit is in WALK TEST mode, you can test the following features:
• IDC alarm sensing: To test the alarm capability of each detector, use a pole magnet or canned smoke to activate the initiating device.
If the device is functioning correctly, either of the following actions occur:
- If the walk test signaling option is set to SIG, the control unit pulses the device’s zone number on the control unit’s NACs. After seven
seconds the control unit drops power to the zone, resetting the activated device. Subsequently activating another initiating device on
the same zone sounds a double pulse on the NAC.
- In both the silenced and signaled walk test options the control unit stores the walk test logs under TLOG.
• IDC trouble sensing: To test the control unit’s ability to sense a trouble condition for each initiating device, disconnect one of the IDC
wires at the detector. If the control unit senses the trouble condition correctly, either of the following actions occur:
- If the walk test signaling option is set to SIG, the control unit activates the control unit’s NACs for four seconds.
- In both the silenced and signaled walk test options the control unit stores the walk test logs under TLOG.
• Earth ground sensing: To test the control unit’s ability to detect an earth ground, short one of the control unit’s circuits to earth. If
the control unit senses the trouble condition correctly, either of the following actions occur:
- If the walk test signaling option is set to SIG, the control unit activates the control unit’s NACs for four seconds.
- In both the silenced and signaled walk test options the control unit stores the walk test logs under TLOG.
• NAC trouble sensing: To test the control unit’s ability to sense a trouble condition for each NAC, disconnect one of the NAC wires at
the control unit. If the control unit senses the trouble condition correctly, either of the following actions occur:
- If the walk test signaling option is set to SIG, the control unit activates the control unit’s NACs for four seconds.
- In both the silenced and signaled walk test options the control unit stores the walk test logs under TLOG.
6.6 Setting the time and date
Set the time and date using the PC tool only. Refer to the PC programming manual for more details.
6.7 Uploading and downloading job files
Upload or download files to transfer the control unit’s job files between a service PC and the control unit.
The term upload refers to transferring a job file from the control unit to a PC. The term download refers to moving a job file from the PC to
the control unit.
To start transfer from the control unit, press the ACK and SILENCE key together for five seconds.
