Sensor Replacement Instructions Wanting

I recently had my Telus home security upgraded. The upgrade process went well. A couple of weeks later I received a report that a sensor was not working. I contacted tech support who walked me through troubleshooting steps. It was determined that this new sensor was faulty and a new one would be shipped to me for me to replace the sensor myself.

There are several problem with this process

• There is no expedited shipment. It took over a week for my new sensor to arrive. During that time I was exposed with one door not protected. A more rapid shipment process would be more appropriate.
• The instructions said to start by reading the instructions in the sensor box. This turned out to downloading a PDF. Note for seniors, view the PDF online with magnification. The font is very small.
• The PDF instructions have you putting on the double sided tape and mounting the sensor and magnetic. Fortunately, I'd read ahead and knew there was a device id on the back of the sensor which was needed for 'pairing' the sensor with the control panel. This means the pairing must be done before the sensor is physically installed. If I'd followed the steps I would not have had the device id which would have already been mounted requiring removal of the sensor.
• No where was it mentioned that to activate the sensor all you need to do is pull the plastic tab out. All the instructions seem to assume the installation of a battery.

So, there is a least one big problem with the steps in that the device if is not recorded before installation.

Telus I'd recommend someone review you instructions, for both app based and control panel based, installations.
