Low Current Trigger Method: One or two
positive alarm outputs capable of 30 mA ea.
The operational current will be supplied from a
co12 Vdc auxiliary source. The siren and
voice channel trigger terminals draw only 30 mA
from the control alarm outputs.
A steady 9 to 14 Vdc on Channel 3 (
+S3
) will
activate the Siren sound and optionally the Voice
Channel 1 (
+V1
). A pulsing voltage (.5 to 2 pulses
per second) on Channel 3 (+S3) will activate the
Temporal Coded Bell sound and and optionally the
Voice Channel 2 (
+V2
).
Note:
Pulsing is only detected on teS3
and terminal -VS.
Industrial Buzzer Siren Sound
The industrial buzzer siren sound is triggered by
connecting Channel 3 (
+S3
) and Channel 4 (
+B4
)
together. It may be triggered along with Voice
Channels 1 and/or Voice Channel 2 as described
previously.

Always add a 1.5 Amp fuse in series
with outdoor speaker. Shorting of the
outdoor speaker wires will blow this fuse
but other speaker(s) will still work.
INSTALLATION & HOOKUP EXAMPLES
Standard Method: Control panel with two
alarm outputs capable of 2 Amps max. each.
Single Alarm Output With Switched Negative:
Controls panels such as DSC provide an alarm
output with a switched negative, requiring a
special hookup.
The
-VS
terminal internally activates Voice
Channel 1 and Siren Channel 3 upon a steady
voltage input. A pulsing voltage input (.5 to 2
pulses per second) on terminal -VS internally
activates Voice Channel 2 and Bell Channel 4.
