The advantage and disadvantage of a button door alarm is it’s simplicity. When the door is opened, the button pops up like a turkey timer and sends a signal to the system to register that the door or window assigned to that sensor has been opened. When the button is pressed, the alarm system reads the door as closed. When the door is closed, one half of the “sensor” depresses a button that protrudes from the other half. ![]() Other security companies use a door alarm that is triggered by a button rather than a magnet. ![]() The door only needs to move about an inch to trip the alarm and tampering with the sensor will set off the alarm. Even if an intruder did know where your sensor was, it isn’t possible to disable them from the outside. This means shady characters won’t be able to know where the sensor is located. Because they’re so small and don’t require direct contact, the two halves are almost always out of view from the outside of the door. Also, you can always check the battery life status of your wireless security devices on the touchscreen display of your Cove Touch Alarm Panel.Īlthough wireless door alarms are very easy to set up, don’t let their simplicity fool you into thinking they’re easy to bypass. But fret not, the batteries for the door and window sensors in the Cove Home Security System are rated for a lifespan of more than 5 years. Because this type of door alarm is wireless, these door sensors must run on battery power. These settings can be customized on the alarm panel or within the app, according to your personal preferences. You can also have your alarm system send you an alert when a door is opened if you have the Cove app. If your system is not armed, your alarm panel may chime or announce the name or location of the sensor, according to your preference. If the sensor is tripped, and your system is armed, an audible alarm on the panel will go off. When the part of the door sensor that contains the magnet moves away from the other half of the sensor, the two wires of the reed switch are able to touch, which triggers a signal to your Cove Touch Alarm Panel. To elaborate, one part of the sensor has a magnet inside, and the other part contains a magnetically sensitive trigger called a “reed switch.” The reed switch houses two magnetic wires that are prevented from completing a circuit when it’s sister piece is next to it. When the door is opened, it breaks the invisible connection between the two parts of the sensor, tripping the alarm. The two pieces are parallel with one another, almost touching. Both parts are mounted with an adhesive strip. One part of the wireless door alarm is attached to the edge of the door and the other part is attached to the door frame. Since we want our customers to have the best, wireless door alarms are the only type of door sensors that Cove offers.īut how does a wireless door sensor work? The sensor itself is a two-piece device. The door sensors we recommend are wireless and can be set up by the customer in mere minutes. The hassle involved in installing wired alarm systems usually requires many hours of setup time by a trained professional. Availability of a normally closed contact, in addition to the normally open contact, permits a wide variety of connections in the load circuit.Door alarms can be wired or wireless, although wired models are quickly becoming outdated. The 30 ampere contacts on the relay provide ample capacity to operate the low voltage alarm and indicator. The setpoint, and time delay, meet the requirements of NFPA 1901, paragraph 9-3.3.Įasily installed, the Low Voltage Alarm requires only two wires to sense the battery voltage. ![]() When the voltage drops below the setpoint, and remains low for 120 seconds, the green LED is extinguished, and the red LED is illuminated. A green indicator is illuminated whenever the voltage is normal. The unit contains LED indicators to aid in installation and test. Available for either 12, or 24 volt electrical systems. At that time, a relay is operated, which may be connected to the low voltage indicator and alarm. The Low Voltage Alarm detects when the battery voltage drops below a threshold, and remains low for 120 seconds.
