## Questions & Answers

**Q: Can I use this powered from my doorbell transformer and have it sound the alternate doorbell when tripped?**
A: You would need to determine the voltage that your doorbell transformer works at.  The sensor has 5 wires.  2 power the sensor, it is pretty versatile in the voltage that it works at, so chances are your doorbell transformer will be fine.  the last 3 are an single pole, double throw relay/contactor, with a normally open and normally closed output.  You will want to connect the normally open output to the doorbell, and the input to the door bell transformer.  Be aware that there is potential to burn out your doorbell.  Think about your doorbell, when you press the button, and electromagnet makes a striker hit a chime, and then when power is removed, a spring pushes it into a second chime.  If someone holds down that doorbell, you get a buzzing sound as the electromagnet is continuously working.  If you had this on your driveway, for example, and a car stopped in the beam, the same thing would happen as someone holding down your doorbell button.  It could also happen if a leaf fell into the beam and got stuck on the reflector...  Chances are this wont be a problem, but you wouldn't want it to happen while you aren't home.  There is a fire risk if that door bell magnet or transformer over heated.   Consider adding a timer to the circuit, that once it is powered, automatically opens the circuit until it is powered again.

**Q: Have Christmas display,, want to count the car that come through,  will this do the trick?  The cars willbe running 5 or 10 mph max**
A: The unit will close or open a set of contacts when the light beam is interrupted. If a counter is connected to the unit it will trigger the counter.

**Q: What does "dark on " mean ?   Does it only work at night ?**
A: When the light beam is broken the relay turns on.  This is "dark on" .  When the light beam is reflected back to the sensor the relay is off.  You can choose which contacts on the relay you want to use.

**Q: I am using it to sound an alarm when someone crosses the beam. Using a 12 volt battery. The device has 5 wires. Grey, blue, black, white,brown??**
A: Blue and brown are the power wires-polarity not important.  White is the common.  Grey is NC Black is NO.  IF the alarm circ,unit needs to be OPENED to sound, use the Grey wire. Usually, they are normally open and the circuit needs to be closed to sound, and the Black wirel is used.  Use White and one of the others k or Gray.
