System Description
teleCARE IP
Appendix E: Support for Stuck Button Detection
From NISM version 7.0.0 or later, support for stuck button detection is included. The teleCARE IP
system is able to detect and send out an alarm if a call button gets stuck.
If for example the pull cord of a pull cord module gets stuck because of a damaged or worn out cord,
the teleCARE IP system will automatically generate a stuck button alarm after 15 seconds.
Passive Modules not Supported
IMPORTANT: Due to hardware restrictions, it will not be possible to implement stuck button
detection functionality for passive modules. Therefore stuck button detection functionality
will not be available for passive modules.
Restoring a site backup
When restoring a site backup created with a NISM prior to version 7.0.0, be aware that the backup file
will not include the triggers for stuck button detection. If stuck button support is required, the triggers
responsible for the stuck button detection will have to be added manually to the “Module
Definitions” of the “Site Modules” template.
Button Hold Time
Due to the implementation of the support for stuck button detection, the maximum button hold time
that can be configured for the triggers of the switch buttons, has been reduced to a maximum of 10
seconds, instead of the maximum of 60 seconds in NISM versions prior to version 7.0.0. Therefore be
aware that when restoring a backup file that was created in a NISM version prior to version 7.0.0, any
button hold times that were configured to be longer than 10 seconds, will be set back to 10 seconds.
