Review ADT Magnetic Switch

The ADT 1085 TN and ADT 1085TM magnetic switches are versatile and reliable devices designed for use in various applications where contact closure is required upon the presence or absence of a magnetic field. These switches are manufactured by Honeywell, a leading company known for its innovative and high-quality electronic components.

The ADT 1085 TN and ADT 1085TM are both normally open (NO) switches that operate based on the presence or absence of a magnetic field. The main difference between the two models lies in their housing material and operating temperature ranges.

The ADT 1085 TN is a thermostat version, which means it is designed to be used in temperature control applications. It comes with an adjustable temperature setting that allows users to set the desired temperature, and the switch will activate or deactivate accordingly based on the ambient temperature and the presence of the magnetic field. This switch has a plastic housing and is suitable for operating temperatures ranging from -22 F to 122 F (-30 C to 50 C).

On the other hand, the ADT 1085TM is a general-purpose magnetic switch with a metal housing. It does not have an adjustable temperature setting and is suitable for a wider temperature range, from -40 F to 185 F (-40 C to 85 C). This model is ideal for various industrial and commercial applications where contact closure is required based on the presence or absence of a magnetic field, regardless of the temperature conditions.

Both the ADT 1085 TN and ADT 1085TM magnetic switches feature a quick-connect terminal block for easy wiring and installation. They also have a high contact rating of 10 million cycles, ensuring long-lasting performance and reliability. Additionally, they are RoHS compliant and UL listed, making them a safe and environmentally friendly choice for various applications.

In summary, the ADT 1085 TN and ADT 1085TM magnetic switches are versatile and reliable devices designed for use in temperature control and general-purpose applications where contact closure is required based on the presence or absence of a magnetic field. The ADT 1085 TN is a thermostat version with an adjustable temperature setting and a plastic housing, while the ADT 1085TM is a general-purpose magnetic switch with a metal housing and a wider temperature range. Both models feature quick-connect terminal blocks, a high contact rating, and are RoHS compliant and UL listed.

ADT magnetic switches, specifically models ADT 1085TN and ADT 1085TM, are commonly used in security systems for detecting door or window openings. Here are some pros and cons of buying these magnetic switches from ADT:

1. Reliability: Magnetic switches are known for their reliability and durability. They have a simple design with minimal moving parts, making them less prone to failure.

2. Easy installation: These switches are easy to install and do not require any wiring skills. They come with mounting hardware and can be installed on most doors and windows.

3. Versatility: These switches can be used on various types of doors and windows, including sliding glass doors, French doors, and standard doors.

4. Cost-effective: Magnetic switches are an affordable option compared to other types of sensors, making them an attractive choice for those on a budget.

5. Compatibility: These switches are compatible with most security systems, including those manufactured by ADT.

1. False alarms: Magnetic switches can trigger false alarms if the contact is broken due to reasons other than the door or window being opened. For example, if a magnet gets misaligned due to vibrations or magnetic interference, it can cause a false alarm.

2. Limited range: Magnetic switches have a limited range, and they may not work effectively if the door or window is too far from the switch.

3. Dependence on power: Magnetic switches require a constant power supply to function. If there is a power outage, the switch will not work, and the security system may not be able to detect door or window openings.

4. Limited temperature range: Magnetic switches may not function effectively in extreme temperatures. They can malfunction in temperatures below freezing or in very hot environments.

ADT magnetic switches, models ADT 1085TN and ADT 1085TM, have their advantages and disadvantages. They are reliable, easy to install, cost-effective, and versatile. However, they can cause false alarms, have a limited range, depend on power, and may not function effectively in extreme temperatures.

If you are looking for a reliable and cost-effective option for detecting door or window openings, magnetic switches can be a good choice. However, you should be aware of their limitations, such as false alarms, limited range, dependence on power, and limited temperature range. It is important to consider these factors when deciding whether magnetic switches are the right choice for your security system. If you are concerned about false alarms or want a more reliable option, you may want to consider other types of sensors, such as photoelectric or reed switches. Ultimately, the best choice will depend on your specific security needs and budget.

Details:

Anti-rotation lugs help keep the contact in place, while included cover, spacers, and mounting hardware make setup straightforward. Built with flame-retardant ABS plastic in white, it features positive-clamping screw terminals captured combination-head screws for quick, secure installation. The 1085Tn-ADT is a surface-mount magnetic contact designed for reliable monitoring of doors and windows in security systems. With a inch gap distance and closed-loop, normally-open configuration, the 1085T-N offers dependable performance for both residential commercial alarm applications.
