Trouble States Without Fire Protection - Johnson Controls SWIFT Instruction Manual

Device Operations
Low Battery

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 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. 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 trouble. The panel displays "BATTERY LOW" or "BAT LOW" during a low battery
condition.
Weak Link

The weak link trouble denotes a connection of insufficient primary parent link signal strength. To
resolve a weak link, reduce the distance 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. Ter-
minate 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 FAULT" or "WEAK" for a device that is in the weak link condi-
tion.
Class A Fault

The Class A fault denotes a single connection path from the device. The wireless system is a
Class A system requiring two communication 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 "CLASS A FAULT" or "CL A" during a Class A fault condition.

Jamming

Jamming occurs when a device is overloaded with an interfering RF signal but is able to send out-
going 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 "RADIO
JAMMING" or "JAM" during a jamming condition.
Duplicate Address

Two wireless devices on the same mesh network that are set to the same address will report a dupli-
cate 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 "DUAL ADDR" or "DUALAD" during a duplicate address condition.
Tamper

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:
