## Description

Product Description ULTRAPRO AUDIBLE WINDOW AND DOOR ALARMS — SIMPLE HOME SECURITY ALERT SYSTEM The UltraPro Audible Window and Door Alarms deliver an easy, cost-effective way to monitor entry points and deter unwanted access. Designed for homes, apartments, dorm rooms, offices, RVs and campers, each alarm emits a powerful 120-decibel alert that helps discourage intruders the moment a door or window is opened. Installation is fast and wire-free. Use the included double-sided tape to mount the alarm and magnet in minutes, with no tools required. When the door or window separates the base from the magnet, the alarm activates instantly. An easy-access chime/OFF/alarm switch lets you choose a gentle chime for daily monitoring or a loud siren for security situations. Beyond doors and windows, these compact alarms work well on cabinets, drawers and interior spaces where awareness matters. An LED indicator alerts you when battery power is low, while four included LR44 batteries ensure out-of-the-box operation. With straightforward setup and dependable performance, UltraPro Audible Window and Door Alarms provide peace of mind without complicated installations or ongoing costs. From the Manufacturer Sounds when a window or door is opened

## Questions & Answers

**Q: We want to install alarms in a vacation rental. Will these damage the walls/windows when removed after a week?**
A: The ones I gor today actually did come standard with 3M double sided tape and it sticks great. Dont know if it will damage after being on a few weeks but ai was able to pull it off the wall after about 30 min and no damage.

**Q: I can see they have buttons/switches, are they easy for young children to mess with?**
A: We use this on our son's door. We have it up high where he can't reach it. the sliding button is very tiny and I'm sure they could mess with it if it were in their reach. I had my husband mount it as high as he could. I stood with my arm up so I could reach it cuz I'm shorter than him, lol. My son doesn't touch it out of fear of hearing the noise go off. If the door is open (connection broken) and you turn it on it will chime or "bong" continually until the door is closed. Once my son heard the loud noises he doesn't go near it, lol, plus it's too high anyway. They're cheap enough to give it a whirl for you, but works like a charm for us! We showed our son, "If you open this door, this is what will happen!" and let it go off.

**Q: Can this alarm be installed on sliding doors?**
A: Since sliding doors design vary based upon manufacturer it's hard to accurately answer this request. However, if you can adhere both items of this product side by side - one being stationary, the other being the movable piece, then it will work just fine. In other words, when the sliding door is in the closed position, you must be able to install this product in such a way that when the door is opened, the two pieces "break contact" with one another thereby sounding the very loud and high-pitched alarm.  Hope this helps.

**Q: I found the chime setting extremely loud. is there another product that has a little more bearable chime sound?**
A: Gab, unfortunately the chime sound is around 90 decibels and there is no way to lower that volume. As for any other products that the chime is a lower volume there isn't any that we manufacture.  Jasco Products Tech Support (Manufacturer)
