C.1  Troubleshooting
C.2  Testing W-GATE and Devices
The W-GATE must be tested after installation and as an integral part of a periodic maintenance pro-
gram. The testing methods must satisfy the Authority Having Jurisdiction (AHJ). The W-GATE 
provides optimum performance when tested and maintained in compliance with NFPA 72 ordi-
nances.
NOTE: The W-GATE used with this base must be tested and maintained regularly following the 
NFPA 72 ordinances. The W-GATE should be cleaned at least once a year.
C.2.1  Testing LED Indications
For more information on LED indications, refer to the respective chapters and the attachments pro-
vided for LED indications.
C.3  Testing Wireless Network
The PC Tools application allows you to,
Diagnose and troubleshoot the wireless network and connectivity of the devices. 
Monitor the wireless network topology, quality of the communication links between the 
devices, live and historical event reports for the troubleshooting purpose. 
View the parent-child relationship and the signal strength between the two devices, and 
identifies the device that has lost the communication link with the wireless network.
Trouble Type
Trouble Description
Action
Weak link condition
The weak link trouble denotes a 
connection of insufficient primary 
signal strength.
Ensure spacing between devices, or use 
repeaters.
Class A fault condition
Device loses the connection with 
any of the parent devices.
Ensure spacing between devices, or use 
repeaters.
Jamming
Jamming occurs when a device is 
overloaded with an interfering RF 
signal; but is able to send the 
messages out.
If any jammers are installed in the vicinity of 
the devices, remove them.
Low battery
The low battery event denotes 
that the device has less than one 
month power left to perform the 
required operations.
Or presence of less than four 
viable batteries.
To clear the low battery event, tamper the 
device and replace all the four batteries. 
When a device is tampered, it drops out of 
the mesh network and attempts to rejoin as 
soon as the batteries are replaced and the 
tamper event is cleared.
Duplicate address
Two wireless devices on the 
same mesh network that are set 
to the same address reports a 
duplicate address trouble.  
Change the address of a device to avoid 
duplication.
