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 24 (2W SMK ZONE 8) only when zone 8 is learned into sensor group 26 (fire) and
the Two-Wire Smoke option is on.
Note
Zone 8 must be learned into
sensor group 26 (fire) and
the 2-Wire Smoke feature
must be on for connected
smoke detectors to reset
after canceling a fire alarm.
Table 4 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 8.
Connecting Speakers
Note
Install all sirens/speakers
indoors, in a concealed loca-
tion.
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.
The output can drive a single 8-ohm speaker or multiple speaker circuit of 8-ohms or higher (as
shown in the following speaker wiring diagrams). Compatible speakers are described below.
Note
Do not connect a bell or
piezo siren to the speaker
output (terminals 7 and 8).
15-Watt Speaker (13-060)
For exterior siren applications, connect the speaker to the panel using 18-gauge wire as shown in
Figure 9.

8.3 VDC, up to 30 mA total (combined alarm) current
8.1 VDC, up to 40 mA total (combined alarm) current
7.6 VDC, up to 60 mA total (combined alarm) current
7.1 VDC, up to 80 mA total (combined alarm) current
Caution
!
To avoid disabling the panel speaker output, do not make speaker connections with the
panel powered up.
