I configured the StarLink SLE Fire Radio Input 2 and/or Input 3 as a Supervised Fire Alarm and/or Trouble. Yet every day at the same time the central station informs me of an E373 Zone 992 and/or 993 trouble. When I installed the supplied 10k resistors, I received a restore on these zones. Why do these zones report the same trouble every day?
When Input 2 and/or Input 3 are programmed for Supervision, you must install the 9SLE10KHARN harness and wire accordingly (this harness is installed with two 10k resistors, one in series, the other in parallel; see image at right).
In the normal state, the radio will read about 4.9kΩ resistance; if the Fire control panel goes into trouble, the relay contact opens, changing the resistance to 10kΩ (the radio recognizes this 10kΩ reading as a Fire control panel trouble).
Correspondingly, if the wire between the fire control panel relay and the radio is cut, the radio will read zero resistance, thus detecting the line cut.
With only one 10k resistor installed and the inputs programmed for Supervision, the radio will detect a control panel trouble. If the inputs are not supervised, then use the factory default setting of User Defined with only the 10k resistors installed on the inputs.
