The 2315 series Sentrol garage door sensor is one of the best products ever made for protecting panel or sectional style overhead garage doors. It saves time and money during initial installation, and reduces the chance of future service calls to replace a damaged switch.
A garage door sensor is a magnetic contact used to connect a garage overhead door to a home alarm system. Note that this is an alarm device, and has nothing to do with the photocells used to stop a garage door when an object is in its path.
Not everyone wants or needs the garage roll-up door to be part of the main house alarm system, but those that do need a sensor that is dependable and trouble-free. The Sentrol 2315 garage door sensor is very reliable when properly installed for either professional or DIY security alarms.

Sentrol designed the 2315 sensor to fit the track or rail of a standard
sectional garage door. It can be installed much faster than the older
floor-mounted garage door sensors, mainly by avoiding the need to drill
into the concrete garage floor.
Note that the 2315 Sentrol magnetic contacts will not fit a one-piece garage door. If you have a single-panel, swing-up-type garage door, use a standard garage door sensor and magnet like the Honeywell 958.
The Model 2315 Sentrol sensor is a 2-wire device designed for standard N/C (normally closed) alarm panel zones. If you need N/O (normally open) switches, use Sentrol 2317 rail contacts. These 3-wire devices provide both N/C and N/O connections.
So, what makes 2315 Sentrol contacts so much better? Let’s take a look!
First, the 2315 Sentrol sensor mounts to the track or channel of a sectional panel garage door, rather than on the floor like older models. This automatically avoids some of the most common types of garage door sensor damage. These include:
Second, the Sentrol garage door sensor is specially shaped to easily grab on to the roll-up door track. Simply fit the sensor and L-bracket onto the track, and tighten the setscrew with a nut driver, socket wrench, or even pliers. There’s no need to over tighten the sensor set screw, it just needs to be tight enough to keep the switch from sliding up or down.
And third, the Sentrol garage door sensor can be had with factory installed rugged armored cable. Many other garage door sensors on the market don’t come with armored cabling. This can allow the wiring to be easily damaged, even by objects stacked against the garage wall near the door opening.
