What will cause no output of 24V on the 900-2RS?

Checking the following items:

  1. The setting of the PS914 is set on 24VDC
  2. You measure 24VDC from the PS914 mother board
  3. The 900-2RS is plugged into the PS914 power power supply
  4. Either the fire alarm jumper is in place on the 900-2RS or the fire alarm is a normally closed dry contact attached to the 900-FA board
  5. Measure the voltage between SC and GND on 900-2RS, it should measure 24VDC if not you have a defective 900-2RS board
  6. Then check by closing the contact across SC & I1, it should measure 24VDC between O1 & GND.
