Abstract NA 144 ‘Risk-Based Maintenance of Fire Alarm Systems’
(Edition: 2018-04-09)

The purpose of this NAMUR worksheet is to define risk-based maintenance concepts for fire alarm systems within the applicable standards and based on approaches of the functional safety. Methods, procedures and appropriate maintenance measures are defined for fire alarm systems. These are intended to replace previous preventive maintenance concepts for fire alarm systems which were independent of the risk potential associated with the monitored building and other factors (e.g. self-monitoring of the sensor system).
