Speakers and sirens
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.
Install all sirens/speakers indoors in a concealed location.
Note:
Do not connect a bell or piezo siren to the speaker output (terminals 7 and 8).
The output can drive a single 8-ohm speaker or a multiple speaker circuit of 8 ohms
or higher. When connecting two or more speakers, wire them in series. Wiring
speakers in parallel can permanently damage the panel. Compatible speakers are
shown below.
Caution:
To avoid disabling the panel speaker output, do not make speaker
connections with the panel power on.
15-watt speaker (13-060)
For exterior siren applications, connect the speaker to the panel using 18-gauge wire
as shown in Figure 9 below.

Caution:
Connect only the large speaker to panel terminals 7 and 8 as shown. The
smaller speaker cannot handle output to terminals 7 and 8. To avoid damaging the
speaker, do not connect the smaller speaker to terminals 7 and 8.
