Silent Knight SK-5207: P1
Silent Knight SK-5207·1 view·0 field notes
What This Code Means
The panel has detected a trouble condition with the smoke detector power supply.
Common Causes
- 1Power supply and panel voltage selections are not the same
- 2Short or overload on smoke power terminals (12, 15, or 18)
- 3Loss of smoke detector power
- 4Faulty connection at power supply connector P1
Resolution Steps
Verify that the power supply and panel voltage selections are the same in programming step 2. Check for shorts or overloads on smoke power terminals 12, 15, and 18. Ensure the power supply connector (P1) is securely connected to the 5207 board and measure the voltage to ensure it is within the normal range (between 26 and 28 volts across a 4.7k resistor).
