Wireless Devices

The two LEDs on the devices blink in the same pattern to allow the LEDs to be viewed from any angle. The LED indicators are provided 
in Appendix D on page 55.

The following trouble conditions are unique to the battery powered RF devices. 

The devices (on an  only) indicate the following trouble conditions with a single yellow LED blink every 14 seconds. The wireless 
device will still perform fire protection during the following trouble states.



The low battery event denotes:

• The device has a minimum of one week power left to perform the required operations.

 Or 

• One (or more) of the batteries is missing or dead.

The low battery event is a latching condition. To clear the low battery event, tamper the device and replace all 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. If the device has dropped from the mesh prior to the tamper event, a system reset has to be issued to clear the low battery trou-
ble. The panel displays “LOW BATTERY” or “LOW BATT” during a low battery condition.



The weak link trouble denotes a connection of insufficient primary parent link signal strength. To resolve a weak link, reduce the dis-
tance between devices, place them away from obstructions, or add a repeater. Tamper the device when moving it to a new location. 

Restart mesh formation after a repeater is installed or after a device has been relocated and the tamper condition is cleared. Terminate 
mesh formation once the devices have joined the mesh or allow mesh formation to timeout. Restructuring will automatically start and the 
gateway will reevaluate the link connectivity between all devices and select suitable signal paths. 
Weak link trouble reporting can be disabled at the FACP or at the gateway for installations not requiring primary link connectivity. Refer 
to Section 2.9.4 for more information on disabling weak link trouble reporting. Refer to the troubleshooting section for more information 
on resolving a weak link condition.
The panel displays “WEAK LINK” for a device that is in the weak link condition. 



The Class A fault denotes a single connection path from the device. The wireless system is a Class A system requiring two communica-
tion paths for normal operations. To remedy the Class A fault, ensure adequate device spacing. The use of a repeater may be required. 
The wireless mesh is a self-healing network. If the trouble is not cleared within 5 minutes, additional actions may be required. Refer to 

the troubleshooting section for tips on resolving Class A fault conditions.
The panel will display “RF CLASS A” during a Class A fault condition.



Jamming occurs when a device is overloaded with an interfering RF signal but is able to send outgoing messages. A jamming event is 
detected after 20 seconds of exposure to the jamming signal. In the event of jamming, the device will drop from the mesh network. The 

panel displays “RF JAMMING” during a jamming condition.



Two wireless devices on the same mesh network that are set to the same address will report a duplicate address trouble at the FACP. The 
gateway will respond to the panel with the device type of the first device to join.
The panel displays “DBL ADDR” during a duplicate address condition.



A tamper trouble indicates that a detector is not firmly attached to its base or the cover plate is not properly attached to a module. The 

tamper condition is annunciated in the following ways:

The yellow LED on the device turns on steady for 4 seconds followed by a blink pattern of yellow, yellow, red every 

15 seconds immediately after the tamper condition.

Devices that are in the tampered condition report a latching trouble event. The event is active for 90 seconds before it 

can be removed with a system reset. Once the event is removed, the device reports a “TAMPER” until the device is restored or the point 
is removed from the database.

To clear the tamper, 

•

For a detector, ensure that the magnet has not been removed from the base and the detector is locked together with its base.

•

For a module, ensure that there is a magnet in the cover plate and it is securely fastened to the device in the correct orientation.

Once the tamper event is cleared, the LEDs in the device turn on steady for 2.5 seconds, in the following color patterns that denote the 
battery status.
