Vanderbilt PDM-i12 PIR Installation Guide

This is a quick video on how to correctly wire the PDM-i12 passive infrared detector from Vanderbilt Industries.

This PIR has been around for a number of years, and it extremely popular around the world, and especially popular in Australia, but new customers still have trouble with wiring the detector correctly since the terminal are unlike most other detectors on the market, but today I’ll show how easy it is to install.

But first lets have a quick look at the features of the product.

The PDM-i12 is part of the MAGIC series of detectors from Vanderbilt Industries in Europe, and has it’s origin as a Swiss designed and built product.

The PDM-i12 using:

  • Magic mirror technology
  • Both sensitive and reliable detection performance
  • is has a modern and elegant design
  • it is energy efficient, using only 2.5ma
  • Quick and easy installation

This detector is a 12m wide angle PIR, and an option for a 20m curtain lens.  The detector is the only completely flat faced PIR that i am aware of in the market. lets take a look

Note our discussions today are only on the pdm-i12 seen on the label, we have the detector, instructions and a cable clip.

Notice the design, even with a flat face this detector still manages to have a full look down zone to detect directly under the unit, that’s great Swiss technology.
Because of this, this detector can be fully flush mounted in a wall to provide a totally streamlined appearance.  Apart from the flush mount kit, you can add a PZ-MBG2 mounting bracket for wall or ceiling use.  You can also use any camera bracket with a 1/4 thread to mount the PIR with the optional PZ-CA adapter.  To make the detector pet immune, add the PO-CL pet clip.

To open the PIR the unit from the base plate by inserting your screwdriver and lift, and we can see the terminal block and wiring details.

If we are using the Vanderbilt SPC intrusion panel or a panel with select-able end of line resistance values, we can simply wire the 12v and ground and the C1 and C3 terminals for our zone input, close the detector and you are done. Program your SPC panel for dual 4k7 resistors, and you can have an early lunch. They is no need to watch the remainder of this video.

For the rest of you, stay tuned…

Ok, lets breakdown what we need to do step by step.

Let look at mounting the detector.

it can mounted directly to a wall in four different ways. You can direct the detector left of right using the side screw mounts.

also for mounting under 2.6m in height, use the base top screw mounts. If the unit is mounted higher than 2.6m use the bottom screw mounts, this gives the detector a 2 degree incline to better detect.

You will notice the detector lid has a tamper switch. This is great to detect the face of the detector if removed from the base, but what about if the detector is yanked off the wall. To enable this make sure you use one of these screw mounts for secure to the wall, then if the detector comes away from the wall the plastic mount falls away and the tamper is activated.

Now for the wiring you would have noticed the terminal block wiring and started to scratch you head, as they is no alarm contacts or tamper contacts. You then would have opened the enormous instruction manual and struggled to find English. Since this detector is sold worldwide, the manual is in 210 different languages, so find the diagram in the top right corner, this is our guide here.

I will show you 3 methods to wire the detector. Lets assume your alarm panel uses 6k8 resistor for the alarm and 2k2 for the tamper

Method 1

If you aren’t using 4.7k resistors then remove these. It is important to always remember to remove these.

Cut your resistors using this guide, then insert the 6k8 into INTR and the 2k2 into EOL

Note if you are only using a single EOL resistor, then insert it into INTR and move the jumper to on

Method 2

You can purchase a resistor kit that has your EOL values already set, so you simply insert to pack into the holes. you can purchase these in bags of 100.

Method 3

Use this method if you like the old fashioned way of wiring.

Insert the alarm resistor, in our case the 6k8 across the C1 and C2 terminals. Then install your tamper resistor (2k2 for us) across the the C3 and the spare terminal.
then wire your zone across C1 and spare. Ensure the jumper is on.

For single EOL applications wire the EOL across the C3 and spare, and your zone wiring remains the same. Also ensure the jumper is on.

You can adjust the sensitivity of the detector using dip switch 2 and 3 according to this guide.

As always if you require further information please refer to the show notes below, and I look forward to see you on our next Alarmcorp product video. Have a great,

goodbye for now.
