Positive Siren Output Brown Wire
HORN CONNECTION:
The Brown wire may be connected to the vehicle's existing
horn wire, but a relay and diode must be used to switch the polarity to Negative. The horn
switch wire is typically found at the steering column. Use a digital multimeter (DMM) to
identify the horn wire. CAUTION! Avoid the Airbag circuit! The correct wire will show
Positive 12 Volts normally, and no voltage when the horn is honked. Direct connection of
the Brown wire to the horn itself is not recommended because the average horn requires
The Brown wire is a 1 Amp Positive output designed to operate the electronic siren for
audible confirmations, and also to sound if the alarm is triggered. An alternative to the
siren is to program the alarm to pulse this output to sound the vehicle's horn by adding a
relay and diode. This would require changing Programmable Feature #18 from the preset
steady output to a pulsed output.
SIREN CONNECTION:
The Brown wire may be connected directly to the siren's Red
wire, and the siren's Black wire is connected to (-) Ground.
Mounting The Siren: Find a location in the engine compartment away from the extreme
heat of the engine and manifold. A suitable location will offer a firm mounting surface, will
also allow sound dispersion out of the engine compartment, and not be accessible to a thief.
The siren must be pointed downward to avoid moisture collecting inside it and to enhance
sound dispersal.
pushed to "unlock". Since the security system's output polarity must be reversed from
negative ground to 12 volts positive, an optional doorlock interface must be used. Three
interfaces are available - the models DLP-P3, or the DLS with optional SPDT relays.
Model DLP-P3 - Three pin connector with a transistor converter network which changes
the security system's negative pulse doorlock outputs to positive pulses. Allows direct
connection of the security system's outputs directly to a vehicle with positive pulse
doorlocks. Overall length 20". Easier and more efficient than using relays for vehicles that
have positive pulse doorlock systems.
