Connecting 2-Wire Smoke Detectors
Zone input 6 can be set up (in program mode) to accept 12
VDC, 2-wire smoke detectors by the following manufactur-
ers:
‰ System Sensor models 2100D, 2100TD, 2100S,
2100TS, 2400, 2400TH
‰ Sentrol (ESL) models 429AT, 521B, 521BXT—models
521B and 521BXT require the following dip switch
settings: 1-on, 2-off.

!
Use only the 2-wire smoke detector models
described above. Alarm signals from other detec-
tors may not be processed correctly if the panel
has lost AC power and is operating only from the
backup battery.
When set up for 2-wire smoke detectors, zone 6 can handle
up to 10 smoke detectors with 120 µ A maximum idle cur-
rent per detector. Maximum total loop current allowed in an
alarm condition is 80 mA. The maximum loop resistance
for 2-wire smoke detectors connected to zone input 6 is 10
ohms, plus the 2k end-of-line resistor.
œÌi
When using 2-wire smoke detectors on Zone 6, the
TWO-WIRE SMOKE setting (in program mode) must
be turned on before entering the LEARN SENSORS
menu. See ONBOARD OPTIONS—INPUTS in the
section "Programming the Panel" (page 32) for com-
plete details.

Panel terminal 16 (ZCOM/2W-) cannot be used as a
common loop connection for any other zones, when
using Zone 6 for 2-wire smoke detectors.
Connect one or more 2-wire smoke detectors to the panel as
shown in Figure 12.

CAUTION!
Panel terminal 16 (ZCOM/2W-)
cannot be used as a common
loop connection for any other
zones when using Zone 6
for 2-wire smoke detectors.

Connecting 4-Wire Smoke Detectors
œÌi
For UL Listed systems, 4-wire smoke detectors can-
not be connected to onboard panel zone inputs.
Zone inputs 1 through 6 can be used with 4-wire smoke
detectors that latch and remain in the alarm state until
power is removed and then restored to the detector. The
panel provides this power interruption from panel terminal
8 (OUT2/OC) provided that the output configuration num-
ber is set (in program mode) to 01500.
For more information on output configuration numbers, see
the section "Programming the Panel" and the tables in
Appendix A.
œÌi
The TWO-WIRE SMOKE setting (in program mode)
must be off when connecting 4-wire smoke detectors
to zone 6.
Use only 4-wire smoke detectors that operate on 8.5 to 14.2
VDC.
Connect up to five Sentrol (ESL) model 449AT (GE Inter-
logix part no. 13-360) smoke detectors to panel power input
as shown in Figure 13.
œÌi
Panel terminal 8 (OUT2/OC) must be set to configura-
tion number 01500 for connected smoke detectors to
reset after canceling a fire alarm.
