## Questions & Answers

**Q: Will this work with Comcast xfinity system?**
A: This DSC WS4939 sensor only can work with DSC wireless panels. For Xfinity system, you need Visonc MCT-320 sensors.

**Q: How close does it need to be to the magnet to register as closed?**
A: Usually with a 1/2 inch or so...

**Q: Can you demand to know the "Installer Code" from your alarm company? This sensors cannot be added to your system without it**
A: Ran into the same problem, but if you haven't tried, the manufacturer default for installer code 6321, if you are using the 4 digit, input type. Or you can try the last four digits of your account number from the support company.  My bet is on the first one. Good luck with your problem.

**Q: How do you pair it with the DSC panel?**
A: I have a DSC 1832 and enrolled this to replace a failed wireless sensor, at the keypad (which is either a PK5501 or RFK5501).    You'll need to have the wireless sensor in your hand and look at the number after the "S:"  (it will probably have numbers and asterisks in it).  With that in hand, here's what I did to replace the old / failed sensor.  Press *8 on keyboard, followed by your programmers code (default is 5555), It will ask for a Section and show "---", type 804.  It will ask for for section with two dashes "--", then type the zone number of the failed sensor.  It will display the ESN of there old failed number, just type exactly what you see after "S:" on the label (including asterisks), then hit pound "#" until you are out of programming mode.  Worked for me.  Hope it works for you!
