API-Alarm
API-Alarm Panel Interface
The All-Purpose Interface (API) is a device that can wirelessly interface to
various accessories to complement the performance of the LDS system,
reduce nuisance alarms, and improve the customer's experience and
satisfaction with the system. It should be placed within 100' of the
control panel to maximize signal strength. A few of the common
adaptations and applications are described below.
POLD+ if you were to wire up a POLD sensor to the API (and it is
polarized) the Sensor would have its black wire going to GND and its red
wire going to POLD+. When the POLD+ goes to GND level, it trips.
To reset the alarm: First make sure that the sensor is completely dry. Then press
and hold the TEST button on the API for 3 seconds. The LED will go dark until
the button is released and will stay lit until the alarm condition is cleared at the
control panel.
The opto isolators used for HOME/AWAY and STANDBY have non-committed inputs for maximum flexibility.
The input voltage is not to exceed 12 volts.
The IN+ would need to go to the positive input potential through a switch or wire.
The IN- would need to go to the negative or GND potential through a switch or wire.
Each opto-isolator has its own IN+ and IN- and they can be wired for high going signals, or GND (low) going signals.
The +REF and -REF signals are used as the voltage references for the optos. +REF usually reads 12VDC, while
-REF is GND.
If (for example) you want the STANDBY to activate when its signal is grounded, then you would wire up the IN+ of
STANDBY to the +REF and the IN- goes through a switch or relay to GND. If connecting to an alarm panel, make sure
that the GND’s are the same potential by connecting its GND to the API GND or -REF pins.
If (for example) you wanted to hook up an Alarm Panel that goes to 12 volts when in AWAY mode. Then wire the Alarm
Panel GND and HOME/AWAY IN- to the API GND or -REF and wire the HOME/AWAY IN+ to the 12 volt AWAY trigger
signal. (HOME mode is when the AWAY mode is not activated.)
