Defeat Protection
The Defeat Protection option is designed to detect attempts of penetration into protected premises by
defeating the S2000R-SMK with the help of an external powerful magnet.
This option is to be enabled/disabled in the configuration of the polling loop controller (see Section 8
of this Manual).
Mounting Location Considerations
Considering the mounting location for the S2000R-SMK, please follow:
The instructions from Section 9 of this Manual.
All your applicable local codes, standards, regulations, and ordinances.
In order Defeat Protection to operate correctly, the Magnet must not be fitted closer than
5 mm to the detector. Otherwise, both reed switch contacts can trigger and a relevant
alarm will be sent
