Simplex 4100ES-S1 - Meter Readings; Table C-1 Acceptable Zone and Signal Circuit Meter Readings

C-2
Appendix C: Checking System Wiring, Continued
Table C-1 lists the correct meter readings for different circuit types. Remember, these
readings must be made with the field wiring disconnected from the 4100ES terminals.
Table C-1. Acceptable Zone and Signal Circuit Meter Readings
Circuit Type
Meter Reading
Class B (spur) Detector Circuit (each circuit)
From zone + wire to zone – wire (each zone)
3.3k (EOLR)
From zone + wire to ground
Open circuit
From zone – wire to ground
Open circuit
Class B (spur) Notification Appliance Circuit (each circuit)
From B+ wire to B- wire:
In one direction
In the opposite direction
10 k (EOLR)
Low resistance (Load)
From B+ wire to ground
Open circuit
From B– wire to ground
Open circuit
Shielding
Shield to ground
Open circuit
Shield to – wire
Open circuit
Shield to + wire
Open circuit
IDNet Loop
From IDNet B+ wire to ground
Open circuit
From IDNet B- wire to ground
Open circuit
From IDNet A+ wire to ground
Open circuit
From IDNet A- wire to ground
Open circuit
Note: measuring from IDNet B+ to A+ wires, or B- to A- wires will read as a high
resistance or open circuit due to the channel isolators in the loop.
