Using 2-Wire Smoke Detectors on Zone 1
Zone 1 can support up to 16 2-wire smoke detectors.
The alarm current on zone 1 supports only one
smoke detector in the alarmed state.

These smoke detectors are UL Listed for use
with the VISTA-50P/VISTA-50PUL and are
the only 2-wire smoke detectors that may be
used.
Wiring 2-Wire Smoke Detectors to Zone 1
2K EOL resistors must be used on fire zones
and must be connected across the loop wires
of each zone at the last detector.
To wire 2-wire smoke detectors to zone 1, perform the
following steps:
Step Action
1 Select up to 16 2-wire smoke detectors from
the list of compatible detectors.
2 Connect 2-wire smoke detectors across zone 1
terminals (10 and 11) as shown in Figure 3-
10. Observe proper polarity when connecting
the detectors.
3 Connect the EOL resistor at the last detector
in the loop across the zone 1 terminals. The
EOL resistor must be connected across
the loop wires at the last detector.
