Figures are based on maximum wiring resistance of 100
Ω.
Normally Closed
Connect hardwired devices to any Z terminal and any Com terminal. Wire normally closed devices in series.
Note: For UL Installations, do not use normally closed loops.
Figure 2-9 Normally Closed
The following table shows zone status under certain conditions for NC Loops:
Table 2-5 NC Loop Status
Loop Resistance Loop Status
0
Ω
(shorted wire, loop shorted) Secure
Infinite (broken wire, loop open) Violated
Single End-of-Line (SEOL) Resistor
When SEOL resistors are installed at the end of a zone loop, the alarm panel detects if the circuit is secure, open, or shorted.
The SEOL resistor must be installed at the end of the loop for proper supervision.
To enable SEOL supervision, program section [013], options [1] and [2] to OFF.
Note: This option should be selected if either normally closed or normally open detection devices or contacts are used.

The following table shows zone status under certain conditions for SEOL:

Loop Resistance Loop Status
0Ω (shorted wire, loop shorted) Violated
5600Ω (contact closed) Secure
Infinite (broken wire, loop open) Violated
