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.

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.
