View source for HawkEye Motion Sensor Setup

==Introduction==
The following instructions cover the configuration of the HawkEye (MS12A) Motion Sensor.  At a minimum, a Transceiver (TM751 or RR501) or ActiveHome Pro Interface (CM15A) is required to test the HawkEye. The HawkEye is for indoor use only.

==Setup==
When batteries are installed in the HawkEye, the default House/Unit code is A1.

===Testing The HawkEye===
*Set the Transceiver's House code dial to A. Or, make sure the motion sensor's house code is listed in ActiveHome Pro's Transceived House Codes.
*Temporarily plug a lamp with a regular incandescent bulb into the outlet on the bottom of the Transceiver (first make sure the lamp's power switch is ON).
*Plug the Transceiver into an electrical outlet.
*Press the ON/OFF button on the face of the Transceiver. You should hear the relay inside click, and the lamp will turn on or off.
*Press the ON/OFF button again to turn the unit (and the lamp) off.
*Extend the Transceiver's (or Interface's) antenna.
*Remove the HawkEye's battery cover.
*Install two AAA batteries (insert them as displayed in the diagram in the battery compartment).
*Press the HOUSE/ON button located in the battery compartment.
*The red LED light at the top of the HawkEye flashes (pulsates) to tell you it is transmitting.
*A moment later the relay in the Transceiver module should click and the lamp turn on.
*If the lamp is currently on, press the UNIT/OFF button on the HawkEye.
*The red LED light at the top flashes.
*Then the Transceiver should click and the lamp turn off.

===Setting The House Code===

*Press and hold the HOUSE/ON button (located in the battery compartment).
*The red LED light flashes.
*A few seconds later, the HawkEye tells you its current House code setting.  One flash for A, 2 for B, 3 for C--all the way to 16 for P.
*When you see this, release the button immediately.
*If you want to keep the current setting, take no further action.  A few seconds later, the HawkEye will timeout.  It indicates this to you with a longer flash.
*If you do want to change the House code, once the HawkEye reports its current setting, press the button the number of times equal to the House code you wish to set (Once for A, twice for B, thrice for C, etc.) and '''hold the button down on the last press'''.  You want to determine which code you are using before you begin programming, because the HawkEye will only wait a few seconds for you to begin entering the new code.
*A few seconds later, the red LED light will flash its new setting (1 for House Code A, 2 for B, etc.).
*If the programming fails, the red LED light will show one long flash.  This can occur if you wait too long to begin programming, you press the button more than 16 times, or you press the UNIT/OFF button.  If the programming procedure fails, you can start it over.

===Setting The Unit Code===

*Press and hold the UNIT/OFF button (located in the battery compartment).
*The red LED light flashes.
*A few seconds later, the HawkEye tells you its current House code setting.  The total number of flashes equals the unit number.
*When the HawkEye starts to report its current setting, release the button.
*If you want to keep the current setting, take no further action.  A few seconds later, the HawkEye will timeout.  It indicates this to you with a longer flash.
*If you do want to change the unit code, once the HawkEye reports its current setting, press the button the number of times equal to the Unit code you wish to set and '''hold the button down on the last press'''.  You want to decide on the code to use before you start programming, because the HawkEye will only wait a few seconds after it reports its current setting for you to begin entering the new code.
*A few seconds later, the red LED light will flash the new setting.
*If the programming fails, the red LED light will display one long flash.  This can occur if you wait too long to begin programming, you press the button more than 16 times, or you press the HOUSE/ON button.  If the programming procedure fails, you can start it over.

==Behind The Scenes==
===Motion Detection===
The HawkEye "sees motion" using passive infrared (PIR) detection. "Passive infrared detection" is basically the detection of a change in temperature, often from body heat. If someone walks into an area protected by a sensor with Passive Infrared (PIR) Detection, then their body heat is detected, and the sensor is triggered. When the temperature is returned to its normal level, the motion sensor resets.

'''Sensor Detection vs. Motion Direction'''

For best results, mount the HawkEye so the person entering the area cuts across the HawkEye's field of view.  Do not mount the HawkEye near heating or cooling sources (heat vents, air conditioners, direct or reflected sunlight) as this may falsely trigger it.

''Sensor's fields of view and detection range''

===Dawn/Dusk Detection===
When its photo cell detects the change from light to dark, the HawkEye motion sensor sends an On command to the unit code one higher than itself; when it detects the change from dark to light, it sends an Off command. For example, you have a motion sensor controlling a kitchen light. They are both set to A1. At dusk, this motion sensor turns on a night light set to A2, which it then turns Off command at dawn. This is perfect for porch lights and night lights.

The lamp that will be controlled by this feature should not be located near the HawkEye.  If the lamp is too close, the light generated will cause the HawkEye to "think" it is dawn; therefore, it will send the OFF command.  The light turns off, and the light level in the room drops.  The HawkEye will then "think" it is dusk and send the ON command.  The cycle repeats.
