BALANCED MAGNETIC SWITCH LEVEL 2
INSTALLATION INSTRUCTIONS
This level 2 BMS is to be connected / used with UL Listed Burglar Panels / Systems, Switch and Magnet must be
aligned for corrrect operation!
WOOD DOORS — NON FERROUS APPLICATIONS:
Mount in desired location and orientation using #6 pan-head screws with a minimum recommended length of 1/2 inch.
To ensure the highest security, keep the gap as small as practical. A 1/32” gap is recommended but the switch will operate at a maximum
1/8” gap.
The exible cable may exit the switch from either the left of the right side by removing the two #4 athead machine screws located on the
base of the switch and ipping the switch 180°. Refasten the screws but DO NOT OVERTIGHTEN THE SCREWS.
After the switch and magnet have been mounted, remove the SWITCH BASE and temporarily mount the TAMPER INSERT, using the
same #6 screws, in the same location that was used to mount the SWITCH BASE. Permanently mount the TAMPER INSERT using a
third #6 screw in the location shown in the drawing. Remove the SWITCH BASE mounting screws and re-install the switch base over the
TAMPER INSERT. The tamper circuit will alarm before the switch can be removed.
STEEL DOOR AND FERROUS SURFACE APPLICATIONS:
When mounting the switch and magnet on ferrous surfaces such as steel doors and safes, follow the above installation instructions, but
you must also install the enclosed 1/4” thick spaces under the switch and magnet to achieve a 1/8” operate gap.
Use #6 screws (stainless steel recommended) with a minimum recommended length of 1-1/2”.
Use Spacer Kit (part number: N707AUSPKIT) for installation on offset surfaces to achieve correct alignment.
