2-2.7 SW1, Positions 7 and 8: Re-alarm Time
Configures the unit’s re-alarm time. Set the switches as below for desired (approximate) re-alarm times:
1 1 = 24 hours
0 1 = 16 hours
1 0 = 8 hours
0 0 = Disabled; no re-alarming once silenced (factory default)
2-3 SW2 – MODBUS ADDRESSING
Configures the unit’s RS485 address. The unit’s address is set in bits and can range from 00000001 to
11111110 (1-254 in decimal notation).
00000000 = No Address (factory default)
00000001 = 1
00000010 = 2
00000011 = 3
…
11111101 = 253
11111110 = 254
2-4 SW4 THROUGH SW9
Configures each zone as a Leak Detection Cable input or a Dry Contact input. If configured as a Leak
Detection Cable input, the zone requires a 4-wire leak detection cable (SC) to monitor. If configured as a
Dry Contact input, the zone requires a 2-wire dry contact device to monitor. If any zone is not desired to be
used, set the zone to Dry Contact and normally open (factory default) to avoid unwanted alarms.
SW4 Up = Zone 1 is a Dry Contact input
SW4 Down = Zone 1 is a Leak Detection input
SW5 Up = Zone 2 is a Dry Contact input
SW5 Down = Zone 2 is a Leak Detection input
SW6 Up = Zone 3 is a Dry Contact input
SW6 Down = Zone 3 is a Leak Detection input
SW7 Up = Zone 4 is a Dry Contact input
SW7 Down = Zone 4 is a Leak Detection input
SW8 Up = Zone 5 is a Dry Contact input
SW8 Down = Zone 5 is a Leak Detection input
SW9 Up = Zone 6 is a Dry Contact input
SW9 Down = Zone 6 is a Leak Detection input
2-5 R1 – LEAK DETECTION CABLE SENSITIVITY SETTING
This potentiometer allows users to manually adjust the sensitivity setting for all six zones. Turn the dial
clockwise to make the zone less sensitive. This means a leak will be reported in that zone when a large
amount of water is present. Turn the dial counterclockwise to make the zone more sensitive. This means a
leak will be reported for the zone when a small amount of water is present.
This potentiometer can be overridden through the LDRA6’s craft port configuration for individual zones
(see section 4-3.3 for details).
