• System Sensor models 2100D, 2100TD, 2100S, 2100TS, 2400, 2400TH
• 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
detectors may not be processed correctly if the panel has lost AC power and is operat-
ing only from the backup battery.
When set up for 2-wire smoke detectors, zone 8 can handle up to 10 smoke detectors with
120 uA maximum idle current per detector. Maximum total loop current allowed in an alarm con-
dition is 100 mA. Connect one or more, 2-wire smoke detectors to the panel as shown in Figure
11.
Note
The Two-Wire Smoke set-
ting (in program mode) must
be off when using 4-wire
smoke detectors. See
ONBOARD OPTIONS—INPUTS
in the section “Programming
the Panel” for complete
details.
Connecting 4-Wire Smoke Detectors
Zone input 8 can be used with 4-wire smoke detectors that latch and remain in the alarm state
until power is removed, then restored to the detector. The panel provides this power interruption
from terminal 23 (2-wire smoke power +), provided that zone 8 is learned into sensor group 26
(fire).
Note
Zone 8 must be learned into
sensor group 26 (fire) for
connected smoke detectors
to reset after canceling a fire
alarm.
Table 5 describes the minimum available panel power. Use only 4-wire smoke detectors that
operate at these power limits. Connect up to five Sentrol (ESL) model 449AT (part no. 13-360)
smoke detectors to panel power and zone 8 input as shown in Figure 12.
Connecting Speakers
The panel provides one siren driver output for intrusion (steady), fire (temporal 3), and auxiliary
(on-off-on-off) alarm sounds. This output trips only for partition 1 alarms.
