X10 RF PIR - MS13E2 "Hawkeye"

  • Turns on X10 lights when someone enters a room at night
  • Turns lights on when it gets dark and off when it gets light
  • Sends wireless (RF) signals to X10 RF receivers or X10 security systems
  • Use with intelligent 2-way X10 controllers to activate macros
  • Compact & attractive measures approximately 2.5" x 2.6" x 1.5"
  • Time delay between motion stopping & off signal adjustable between 1 minute & 256 minutes (instead of a fixed 6 minutes)
  • Dusk/Dawn feature can be easily enabled so lights/appliances can be turned on whilst it is dark

Powered by 2 x AAA batteries, this RF PIR is a must if you don't want to re-wire. Simply select which Address and House Code you want, fit some batteries, then attach to a wall/ceiling. The unit now includes an EPROM so that when the batteries run out, the unit keeps it address settings intact.

The unit is programmable so it is possible to make it only detect when it is dark or to detect all the time. It is also possible to set a delay, so that when it sends an "On" it can delay between 1, 2, 4, 8, 16, 32, 64, 128, or 256 minutes before sending an "Off" command. Finally the unit can be used to sense dawn/dusk, and could be used to control lights accordingly (the MS13 will send dawn/dusk commands on it's set address +1, so if it is set as A1, when it gets dark A2 will be turned on, and when it gets light A2 will be turned off).

The unit sends RF (radio) signals to an optional X10 RF receiver (TM13). The TM13U will then send the X10 signal down the mains line, to an awaiting X10 receiver (like an AM12, LM12, LW10 or AW10). It can be used either indoors or outdoors (when using outdoors the unit should be sheltered).

The picture on the right shows the size of the MS13 when compared to a 3.5" floppy disc. As you can see the unit is very small, and can be placed in a room virtually unnoticed.

The MS13 can be setup in 4 different modes:
Mode 1 - Motion Sensor is on during the day. Dawn/Dusk Sensor is off
Mode 2 - Motion Sensor is off during the day. Dawn/Dusk Sensor is off
Mode 3 - Motion Sensor is on during the day. Dawn/Dusk Sensor is on
Mode 4 - Motion Sensor is off during the day. Dawn/Dusk Sensor is on

Most people would want to use Mode 2 or Mode 4

The MS13E has been recently redesigned and now has an aerial that is detachable from the top of the unit. This gives the unit greater range.

We have tested the practical RF operating range (the distance between the MS13 and a TM13) and it is approximately 25 feet, however your own mounting/circumstances may mean the range is slightly shorter or longer.
