Sense Input Connections

The Sense Inputs of the M86A are used to conditionally execute macros and to trigger
Event Maps that have been programmed into the System Controller using the ELAN
configuration software.
When used with a conditional macro the sensor is connected to the device being
monitored. The ELAN configuration software can be used to create a macro that checks
the status of the sensor prior to issuing a command. This "conditional programming" can
be used to prevent a TV, for example, from being inadvertently turned on or off when
changing sources or turning a zone on or off.
Event Maps can be programmed that execute a command or sequence of commands when
a Sense Input is triggered. For example, a driveway sensor can be used to activate an
ELAN contact closure sensor to trigger an Event Map that turns on the outside lights. The
status of a light sensor can be used to make the triggering of the Event Map conditional. If
it is daytime the lights don't come on. If it is nighttime, they do.
The M86A provides +5 VDC to the TIP (VSNS) connection to power the Sensor. When the
Sensor is activated, it shorts the ring (SNS) to the sleeve (GND) thereby triggering the
M86A's Sense Input.
Available ELAN sensors include: AUDIO, VIDEO, CONTACT CLOSURE, VOLTAGE,
LED/LIGHT, CURRENT/MAGNETIC FIELD and DOORBELL sensors.
