Hold-open systems are subject to inspection per DIN 14677 — monthly by the operator, annually by a specialist contractor. Failing this obligation means loss of insurance cover in a damage event and personal liability. We deliver compliant maintenance — completely documented, reliably scheduled.
Maintenance of hold-open systems consists of two levels: the monthly function test by the operator (press the smoke test button, check closing behaviour, log book entry) and the annual expert inspection by a specialist contractor. The latter covers measurement of smoke-detector sensitivity, magnet holding force, closing speed, trigger time, battery status and wiring. We perform the annual expert inspection — optionally with training of your staff for the monthly self-inspection.
