## Questions & Answers

**Q: Once the alarm stops after two minutes, does the system resets itself to continue the protection?**
A: This was copied from above......
2,The loud siren host alarm without flashing,also the alarm time and volume can't be adjusted,when the sensor is triggered,the siren will alarm at once,if no one disarms the siren,it will keep alarming about 2 minutes and stop automatically,then it's will be in disarm status till you arm it.

**Q: Can I add a strobe light to this system?**
A: Hi friend,
If you want to take apart the siren and add a strobe light, we advise not to do that, you can try to add an extra strobe siren to work with this system, here is the link for your check, then you just need to add accessories to strobe siren after receiving. Here is our customer after-sale service contact information: fuers.csc01@outlook.com, any question, welcome to contact us, we will help you solve it there. Thanks.

**Q: Is there an extension cord available for the alarm? The alarm will be set up outdoor on a tree and need a 50-60 foot power cord extension.**
A: I have had 3 of these in service for about a year, they all work fine after initial setup. I have had 2 "false alarms" during that time. One at 2 AM...there was no entry after I checked, but on the way out, I did find that the door sensor had lost adhesion to the metal door, fell off, and that caused the alarm. After attaching it back more permanently, not problem.
The other "false alarm" (again, no entry) I found that one motion sensor was not blinking red.....dead 9V battery. A quick battery replacement, and the alarm was armed again. One horn is in the out building, the other horn is in the house. Both horns went off when triggered. Tough to find a better system for the money, and the customer service has been great so far. (All my horns/sensors are inside, can't speak to exterior use, but the horn looks durable enough.)

**Q: Does this system really require 220 volts to operate as stated ?**
A: 220 is never needed for anything but maybe a stove, dishwasher hookups. Generally a good size welder requires 220v. These have to be simply household plug-in capable and it should probably say that a little more clearer.
