Whats a good remote door alarm or motion sensor?




I preferably need a door alarm that is really small, like two little magnets would work best.. it cant be big and noticable.. at all. also it must be able to alarm like 30 feet away to the reciever or what ever

How do you disarm a window chime?




I want to sneak out but we have an alarm system. We dont ever turn the actual alarm on but the chime is on 24/7. It’s magnetic but I don’t know what kind of magnets to use or where to put them. Also it’s a Honeywell system. Please be step by step specific with your answers.

I have already done the removing of the sensors and just making them touch, but the sensor in the wall is very faintly magnetic and none of my magnets are strong enough to trip the sensor. and when i pull the trip out of the DOOR it will stick to the one in the wall and not set the alarm off. The only problem is that when i do this, the door is still cracked open. I want to be able to open and close the door freely without tripping the sensors.

I have the magnets on doors only.
And everytime i open a door the machine beeps.

I heard if i but a magnet on one of th sensors it’ll allow me get out without any beeps.

Now, which one do i put the magnet on, the one ON the door or the one that isnt ON the door?

And it wont activate anything, right?
Thank you very very much.

How To Sneak Out w/ Alarm System?




Alright, here the situation. My parents have an alarm system that has alarms on the doors and windows. All are magnets. Our alarm has a chime feature that lets them know if a window or door is opened. I can diable the chime sometimes, but only if one of them aren’t sleeping by the alarm. How can I get past these alarms without triggering it in any way?

Science home work help!?




Here is the problem. Closed fire doors can slow the spread of fire between rooms. In some buildings, electromagnets controlled by the building’s fire alarm system hold the fire doors open. If a fire is detected, the doors automatically shut. Explain why electromagnets are used instead of permanent magnets.

Please help me!

What is the best alarm system to keep people in?




I run a program for teenagers. Boys and girls in separate rooms, with a supervisor in between. We have tried window and door alarms, but the kids just put magnets by them, or figure out how to deactivate them. Are there any really good alarm systems out there for windows and doors that they might not be able to figure out?
