VISION 2460 INSTALL GUIDE
13
Supplies (–)GND (1A) to power either a 24V siren or the vehicle’s horn relay
during a security breach. The
2460B
comes with a 4-wire siren that has an
internal backup battery (see
Fig-6
below).
ORG
(–) Horn/Siren Output
All vehicles should have a horn relay. NEVER bypass the vehicle’s horn
relay and connect the ORG wire directly to the horn! Connect ORG to
the (-)GND side of the horn relay’s coil if it’s (-) controlled. If the horn
relay is (+) controlled, you’ll need to invert the polarity of the ORG wire.
Vehicle’s Horn Relay
We recommend using 1
optional
dark-red PosiLock connector for con-
necting the ORG wire to a siren. Also, we know it’s easy to connect
the siren’s (–) Ground wire to the bolt used to secure the siren’s metal
mount, but rust could cause a faulty Ground over time. We suggest
connecting the siren’s Ground wire directly to the car’s Battery Ground.
PosiLock Connectors
When installing the 2460B (backup siren), we strongly suggest you
avoid connecting the siren’s RED wire in parallel with the Power wire
of the 2460. For example, if you splice Power off the OBD plug for
the 2460 control unit and for the backup siren, the siren may cause a
voltage drop that may cause a 2460 malfunction. We recommend you
connect the siren’s RED wire directly to the vehicle’s +24V battery post.
