The RFAC-DW-10 spacer kit allows RADION installers and technicians to properly align the RADION door/ window contacts with their corresponding magnets across a wide variety of door/window and frame designs. The spacers also help further separate the magnet/reed switch from metal mounting surfaces which can reduce effective gap width. The result is a faster installation that is more effective in reducing false alarms. System overview The spacer kit allows for better alignment between the reed switch contact and the magnet when doors or windows do not perfectly align with the surrounding frame. This improved alignment creates a more reliable function of the switch, making the system easier to install, and also providing improved resistance to false alarms. Mounting magnets and reed switch contacts on metal doors can cause magnetic interference, reducing the effective gap distance. Stack the appropriate number of base and magnet spacers to compensate for differences in height between the detector and magnet. The durable plastic spacers include alignment pins and receptors for easy stacking and alignment, and fully support the wall tamper feature of the RADION door/ window contact detector. The matching color also provides an attractive, finished appearance.
