SA1-LP Speaker Driver Instructions
The SA1-LP is a single speaker driver designed to connect to the audio output of DVRs, IP
cameras, remote monitoring equipment etc, for talk down applications. Note- the audio input of
the SA1-LP is "line level" (0db).
Speaker Placement
Locate the speaker as close as possible to the area of interest in the space to be monitored. Do
not mount the speaker near air conditioning vents, light fixtures or electrical equipment. The
speaker should be placed at least 5 feet away from the subject(s) to be addressed. A speaker is
still usable in the range of 15-25 feet but is dependent on the level of background noise in the
area. Experimentation in the environment will determine what distances work best.
SA1-LP location and power
The SA1-LP interface box is designed to be located next to a DVR or IP camera. The SA1-LP
requires a 120VAC power source within 3 feet of its location. If this is not possible in your
application, you can splice in up to 100 feet of 18 awg, 2 conductor cable to extend the distance
between the AC power source and the SA1-LP.
Cable Run
Run a 22 gauge, stranded, two conductor shielded cable between the SA1-LP amplifier and the
speaker. Keep the cable run distance under 1,000 feet (70v mode only) and away from AC power
sources, light fixtures and electrical equipment. See Figure 1 for connection diagram.
SA1-LP level control
The speaker level can be adjusted to a higher or lower volume. Experiment with the level control
to achieve the desired volume.
70V / 8 Ohm direct switch
If you want to use an 8 Ohm speaker, place this switch in t he 8 Ohm position and limit your
speaker cable run to 250 feet. If your are using a 70V speaker, place the switch in the 70v
position and pick the wattage tap closest to 2 Watts or use an ETS Sound Surveillance speaker.
SA1-LP audio input.
This input is line level (0db). Connect this to the audio output of your DVR, IP camera, etc. If the
audio output are screw terminals, cut one end off the supplied patch cable and strip back the
wires. Connect the center conductor to "+" terminal and the shield to the "-" terminal.
