Zone wiring - normal:
Normally open detectors are connected in parallel with the end of line resistor.
Normally closed detectors are connected in series with the end of line resistor.
A combination of N/O and N/C may be used.
Zone wiring - dual end-of-line (Tamper)
Only normally closed switches may be used in this configuration.
The normally closed tamper is connected in series with the feed or return line.
