Technician guide: Magnetic proximity sensors for doors and lift platforms

Time required: 90-120 minutes

This guide covers the installation of magnetic door sensors.

The device's configuration file must be updated to enable white wire ignition detection when a 3-wire (hardwired) power connection is made. Contact Support to apply this update if the device does not recognise the vehicle's ignition status.

Preparing to install the sensors

Gather the parts

• CalAmp 36xx with ECMD DLC cable and I/O harness kit
  • F39534 - Connectorized I/O harness
  • F39381 - Magnetic proximity sensor

• Xirgo 63xx with ECMD DLC cable and I/O harness kit.

For Carrier Installs:

• F39340 - Connectorized Relay Socket
• F39338 - 12V Relay

Gather your tools and supplies

Use size #6 by 1" (25mm) or 1-1/4" (30mm) long zinc plated screws with a hex washer head, or #6 size zinc plated bolts with a lock washer or serrated hex head. Screw and bolt length can be adjusted based on the application. the sensor's mounting hole size is .156".

When installing on doors or lifts that require mounting the sensor outside where it is exposed elements, you must use upgraded screws as noted above. Pro-installers may purchase and submit the cost of these screws as a flat rate charge for reimbursement. Please contact the assigned implementation agent to have it added to the PO.

Depending on your vehicle type, you might need some of the following tools:

• 4 conductor 22 AWG stranded wire or better with PVC jacket, foil shield, and ground drain wire
• 1/2” (12.5mm) extra-long drill bit for metal, up to 24 inches long to drill the front wall of the refer
• 20-30 1/4” (6mm) plastic or nylon cable clamps per reefer
• 1/2” (12.5mm) cable clamps (5 per refer to hold the cable outside the refer)
• 3/8” (9.5mm) split loom up to 70 feet per install
• Various grommet sizes (at least one 3/4” (19mm) grommet per reefer)
• Silicone Sealer All weather non-corrosive silicone to seal grommets and reefer walls
• 20-30 self-tapping screws size #10 3/4” (19mm) for metal per install
• Numerous red, blue, and yellow heat shrink butt connector sizes
• 25-35 self-tapping screws size #10 1/2” (12.5mm) to secure cable clamps per install
• A powerful cordless drill with extra batteries

Preparing to install the sensors

The Sentrol 2507-A is a magnetic N/O or N/C door sensor with three wire leads. Follow the instructions below to send the vehicle tracker input a ground signal trigger when the door is open:

• Installers must ground temperature probes, ground drain wires, and door sensors to one of the device's available I/O harness ground wires. Do not make a chassis ground. Magnetic door sensors are too sensitive to ground noise to use a chassis ground.
  Test or “Ohm out” your multimeter leads by selecting the Ohm function and touching the leads together. The multimeter should read .5 Ohms or less.

Red = NC (normally closed) - Connect to the vehicle tracker sensor input wire

White = NO (normally open) - Unused

Black = Common - Connect to an available vehicle tracker ground wire shown in the CalAmp 3640 I/O harness wiring diagram.

Installing the sensor

Mount the sensor switch to a fixed point/frame, and the magnet to the door oriented so their text reads in the same direction.

1. Mount the sensor switch at the desired location.
2. Set your multimeter to read Ohms, and attach its leads to the switch’s black and white wires. The meter should read infinity with the magnet away from the switch.
3. Bring the magnet toward the switch until the multimeter reads 0 ohms and mark this position. Continue moving the magnet towards the switch until the meter reads infinity and mark that position.
4. Position the leading edge of the magnet between the two marks you just made and mount the magnet using the mounting plate as necessary.
