These settings will selectively create events that the API
can generate and transmit to the control panel. DIS means
that function is disabled and the system will ignore any
activity on those input lines. ENA means that function will
transmit and the panel will respond to input activity on
those lines.
The LED will flash briefly during data transmissions and
glow solid when the ALARM is active.
The RELAYS both operate together (as of rev 1.00).
• If the API is in Dial Position 7, the API relays will activate
when the system goes into alarm, and deactivate when
the user clears the alarm.
• If the API is in Dial Position F, the API relays will activate
when the system goes into alarm or when the water is
turned off (via control panel or web), but relays will only
deactivate after the water is turned back on.

API INSTALLATIONS
ATTENTION: Putting the leak defense system
in standby means water flowing into the home
is NOT monitored. A leak will go undetected in
standby mode.
DIAL POSITIONS:
F: Triggers on Water Off command (alarm or user
requested).
Ideal for connecting to circ pump switches and
solid state relays
7: Triggers on Alarm Only
Ideal for connecting to alarm panels
Connecting a Four-Hour or
Six-Hour Timer to the LDS API
This accessory is typically installed outdoors for a
gardener or landscaper to remotely and manually put the
LDS in standby (ignore water flow) mode for the length of
time the timer is rotated to.
• Connect the red wire from the timer to IN– (below
STANDBY) on the API.
• Connect the black wire from the timer to –REF on the
API.
• Place a jumper from IN+ (below STANDBY) to +REF.
• The yellow arrow dial on the API should face F.
• When the timer is activated you should see the Leak
Defense control panel switch from Home or Away to
Standby. When the timer runs out, the Leak Defense
should go back to the original state of Home or Away.
