Zone resistance (Excluding EOLR):

ALL OTHER ZONES: 300 OHMS MAXIMUM

The maximum zone resistance is 100 ohms for
zones 1 and 8, and 300 ohms for all other
zones (excluding the 2K EOL resistor).
Wiring 2-Wire Smoke Detectors to Zone 1
Zone 1 has the added capability of supporting 2-wire
smoke detectors. This zone provides enough standby
current (2 mA) to power up to sixteen of the smoke
detectors listed on the following page. Each zone
provides only enough alarm current (20 mA) to power
one smoke detector in the alarmed state. When
assigned zone type 9, the second entry of a Security
Code + OFF sequence at a keypad will interrupt power
to this zone to allow detectors to be reset following an
alarm.
1.
Connect 2-wire smoke detectors across zone 1
terminals (10 & 11) as shown below. Observe
proper polarity when connecting the detectors.
2.
If an EOL resistor is presently connected across
zone 1 terminals, remove it. The EOL resistors
must be connected across the loop wires of
each zone at the last detector.
The alarm current provided by zone 1 will
support only one smoke detector in the
alarmed state.

Unsupervised Usage of Zone 1
Zone 1 can also be used for normally closed,
unsupervised devices by doing the following:
1.
Cut the red jumper on the PC board located above
Zone 1.
2.
Connect closed circuit devices in series with
terminals 10 and 11.
Wiring 4-Wire Smoke Detectors to Zones 1-8
When programmed for fire warning usage, all zones can
monitor 4-wire smoke detectors or N.O. fire alarm
initiating devices. You may use as many 4-wire smoke
detectors as can be powered from the panel's auxiliary
power output without exceeding the output's rating.
Auxiliary power to 4-wire smoke detectors is
not automatically reset after an alarm and
therefore must be momentarily interrupted
using either a normally-closed momentary
switch wired in series with one side of the aux.
power to the smokes, or using a 4204 relay as
described below.
Using a 4204 relay allows the detectors to be reset via
the second entry of a Security Code + OFF sequence.
The 4204 relay must be programmed to activate on
Zone Type/System Operation 54 (Fire Zone Reset).
