Door / Window Sensors for 315 MHZ GSM Alarm System

These Door / Window sensors are for use on the 315Mhz frequency alarm system shown in the photos.

If you are not sure what frequency you need take a look at the photos of the insides of these sensors.

In the photos below you will see on one a silver round electrical component and on the other a silver oblong electrical component.

Now go to one of the sensors you presently have working on your system and on that oblong or round component you have (you will probably need a magnifying glass) it will say 315 or 433.

If the one you have says 315 then these are the ones you need. If it says 443 you have a 433Mhz system and will need the correct 433Mhz sensors. Unfortunately I only have 315Mhz sensors. I do not have 433Mhz sensors.
