How does a door contact work?
A door contact sensor works using a sensor and a magnet. The sensor has an internal reed switch that is closed when it is in direct proximity with a magnet. When the door is opened, the magnet is separated from the sensor. This releases the reed switch, and the sensor alerts the panel.
What is a wireless door contact?
Wireless Door Contact by Honeywell is Innovative And Discrete Protection System For Self Monitoring. This is used when you want to use your system while you are in your premises.
What are door and window contacts?
They are typically known as magnetic contacts, magnetic sensors or door switches. Magnetic sensors use a sensitive reed switch that is triggered when the magnet is moved close or away from the reed. Surface mount door window sensors are the most popular sensors as they are simply attached to the door or window.
What is magnetic door contact?
A magnetic contact is a door and window sensor that functions using an internal reed switch in conjunction with a magnet. This is the most common way for a door and window sensor to operate. These devices are known for being particularly easy to use and enroll with security systems.

Are door contacts normally open or closed?
closedFor the most part, normally closed contacts are used on normally closed protection points, such as doors and windows.
What are contact sensors?
Contact sensors are security devices typically installed on doors and windows. They can notify you and your system in the event a door, window, or gate opens, or send an alert during an intrusion.
What is a door sensor?
Door sensors are an essential component of your home security system: they let you know when someone is entering your home. These devices are made up of two parts, which form a circuit when they're kept parallel to each other.

What is a door alarm?
A door alarm sensor is a magnetic device which triggers an intrusion detection alarm control panel when a door is open or closed. It comes in two parts, a magnet and a switch. The magnet is secured to the door, and the switch is connected to a wire running back to the control panel.
How do door security sensors work?
A door and window alarm sensor works by using a sensor and a magnet. The sensor is placed on or inside the door or window frame. The magnet is placed on or inside the door or window itself. When the door or window is opened, the magnet will separate from the sensor, causing it to activate.
Are door contacts normally open or closed?
closedFor the most part, normally closed contacts are used on normally closed protection points, such as doors and windows.
How do wired door sensors work?
Most are a type of contact sensor that uses a reed switch and magnet. When the door is closed, the magnet keeps the reed switch circuit closed. When the door opens and the magnet is removed, the reed switch circuit opens, triggering an alert or alarm.
What does a door position switch do?
Door position switches are used to detect the open or closed status of an opening and then send this status to a control panel. They come in a variety of shapes and sizes and are designed for monitoring door positions, roof hatches, gates etc.
How does a recessed door sensor work?
A recessed door contact works using a sensor and magnet. When the door is opened, the magnet will separate from the sensor. This will cause a reed switch inside the sensor to activate, and it will alert the system. A recessed sensor is inserted into the door and frame to remain out of view.
Magnetic Contact Alarm Switches
Wire contacts to an alarm system to alert when doors or windows are opened. Mount the magnet to the door or window and mount the switch to the frame. The alarm will activate when the magnet is pulled away by the opening door or window.
Magnetically Actuated Switches
These switches actuate when a magnet comes within sensing distance, and reset when the magnet moves away. They’re often used to detect when a door or window opens. Mount the switch in a stationary position, such as a door frame, and mount the magnet to a movable object, such as the door.
Tamper-Resistant Magnetically Actuated Switches
Prevent unauthorized use— these switches require coded magnets (sold separately) to actuate, and cannot be bypassed using ordinary magnets. They actuate when a magnet comes within sensing distance, and reset when the magnet moves away.
DC Magnetic-Object Proximity Switches
These switches detect magnetic objects— or objects with a magnet attached— through non-magnetic walls. They’re often used to count magnetic items on a conveyor belt that are too far for other proximity switches to detect and in food plants to track cleaners through stainless steel pipe.
Key-Controlled Door Alarms with Strobe Light
Attract more attention with a strobe light as well as an audible alarm. Arm and disarm these alarms with a key. They sound an alarm and emit short, intense bursts of light when a door is opened without authorization and the alarm and magnetic contact are separated. All require a mortise lock cylinder (sold separately) for operation.
Key-Controlled Door Alarms
Arm and disarm these alarms with a key. They sound an alarm when a door is opened without authorization and the alarm and magnetic contact are separated. All require a mortise lock cylinder (sold separately) for operation.
Keypad-Controlled Door Alarms
Arm and disarm these alarms with a programmable code. They sound an alarm when a door is opened without authorization and the alarm and magnetic contact are separated.
