## Questions & Answers

**Q: Hi, can I put 230 vac through these contacts? Just a few milliamps but almost continuously. What is the curremt rating?**
A: No they are designed to be used in a burglar alarm system at very low voltage and current, please read the description for more information.

**Q: Hi, need these in brown?**
A: We do sell them on Amazon but they may be difficult to find. The easiest way is to click on the "electrotec security supplies" name, then click the "electrotec security supplies store front" link at the top of the page and scroll through our products. To find our name on a listing look to the right and hover over our offer, then click our name in the pop up. Unfortunately Amazon don't always make it easy to find the items you need.

Best regards

**Q: I need this to replace a faulty contact. Looking online it looks a straight forward swap. But will the alarm go off when I rewire it?**
A: It should go off as part of the wiring is for the anti tamper circuit and you will disconect this. No big deal just putting your code in stops the sounder (well it does on my honeywell G3)
