Brand: Dahszhi
Description: Package Content
1pcs x Magnetic Switch Alarm + Screws
Type - Normally Closed
Our door reed switches are NC. Please kindly know before ordering.

Door Magnetic Installation Instructions
The Door and window magnets should be installed at the door and the top of the window. The permanent magnet part is installed on the movable door and window. The switch part is installed on the fixed door and window frame. The switch part and the magnet part should be aligned and installed as much as possible. Otherwise deviation from the best conduction area of the magnetic field line and the reed switch contact will shorten the sensing distance. If the misplacement is severely installed, the switch will not sense the attraction of the magnetic field and cause the switch to malfunction.
It is recommended to position the pen before drilling. The door magnet should be away from the string magnetic field interference source such as transformer. Otherwise, the working characteristics of the door magnet will be changed and possible wrong actions may occur.

Product: 3 pcs Brown Wired Door Contacts Surface Mount NC Security Alarm Door Window Sensors.These ¾” Door Contact Position switches (DCS) Work with All Access Control and Burglar Alarm Systems
Brand: INTELLid
Description: These are the door contact sensors that are in use with any and all commercial or residential card access systems as well as all security burglar alarm system. The door position switches operate with a built an internal magnetic reed switch that closes when the opposing magnet comes within ¾” of the door sensor. Hence when the door opens beyond the ¾” point the door position switch will switch from a closed signal to an open signal. When this happens the access control system or alarm system will sense the change in continuity and will know that the door or window has been opened. When the door or window shuts, the door sensor will notify your security system that the opening has been closed.
