SENSOR ADJUSTMENT PROCEDURES
Step 1: Point the light beam emitted by the light source away from the receiver
Step 2: Turn the light source sensitivity adjustment fully clockwise (CW) to its maximum setting
Step 3: Monitor the output LED indicator on the receiver while moving the light beam emitted
from the light source in a scanning motion, first from left to right and then up and down.
Use this technique to locate the mounting position that will ensure the best possible
beam alignment with the receiver.
Step 4: When acceptable beam alignment has been achieved, turn the sensitivity adjustment
fully counter clockwise (CCW)
Step 5: Turn the sensitivity adjustment clockwise (CW) 1/4 turn past the point the output LED
indicator toggles to the opposite state

PARTITION SENSOR WITH THE DLM SYSTEM
Control Relay Terminal A
LMIN-104 +24VDC 5, 6, 7, 8
NOTE: Requires a SPDT (single pole double throw) +24VDC Relay supplied by others
(OMRON LY2-DC24 Relay, PTF08A-E Socket)
• When partition is closed, the coil on the relay will be de-energized
• When partition is open, the coil on the relay will be energized
• 24 VDC Coil of relay connects to
Red = +24VDC
Green Out of Sensor = Common
NOTE 2: LMIN must be set so "Operating Mode" is Partition. In this mode, all four inputs are
dedicated to Partition detection and LMIN cannot be used with any other inputs
NOTE 3: Wall 1 = Input 1 • Wall 2 = Input 2 • Wall 3 = Input 3 • Wall 4 = Input 4
