A — critical
Immediate remediation — trigger disturbed, system non-functional. Operator informed right away.
Annual testing and maintenance of your smoke and heat exhaust system — all smoke detectors, drives, panels and supply-air paths. Log book, defect report and an immediate offer for remediation from a single source.

A SHEV is only as reliable as its last maintenance. Motors wear, smoke detectors get dusty, batteries age, supply-air paths get blocked. The operator is obliged under DIN 18232-2 Annex B, DIN 14675 and the state building code to have the system regularly tested and maintained by a qualified specialist firm — at least once a year, more often for heavily loaded systems. In addition, the operator must perform a monthly visual check (indicator lamps, supply-air paths). Missed maintenance leads to lapse of the DIBt approval and jeopardises insurance cover — management is personally liable in case of damage. We maintain all common systems (D+H, Essmann, STG-Beikirch, SE Controls), document every step in the log book and offer immediate remediation for defects — one contact, one responsibility, one documentation.
Immediate remediation — trigger disturbed, system non-functional. Operator informed right away.
Time-bound remediation (typically 4–8 weeks). Function limited, but trigger possible.
Note for next maintenance. No functional limitation.
Structure and order follow DIN 18232-2 Annex B. Each step with measured value and finding in the test protocol.
Completeness, fixing, labelling, access.
Each loop individually — test gas, trigger behaviour, sensitivity.
Function, labelling, accessibility at all positions.
Opening, closing, run time, limit switches.
Measurement to full opening per EN 12101 or approval.
Doors, flaps and supply-air devices — open on trigger.
Battery status, charge level, self-test of the panel.
If connected: signal exchange and logic with the fire detection panel.
Correct shutdown in storm and rain, if fitted.
All measured values, observations and defects in the test protocol.
NSHEV halls, PSHEV systems, stairwell SHEV.
Rooflight-band NSHEV over large areas — often integrated with high-bay racking.
Powered CO ventilation plus extraction.
Smoke curtains, fans, smoke exhaust dampers.
Theatres, halls, event venues — often with a mandatory inspection expert.
Stairwell SHEV and atrium extraction.
Costs depend mainly on device count, detector loops and accessibility. A maintenance contract with a fixed schedule is usually 10–15 % cheaper than individual jobs.
All prices are indicative per maintenance visit, excl. defect rectification. Defects are offered separately.
Qualification per DIN 18232-2, manufacturer-certified for D+H, Essmann, STG-Beikirch, SE Controls.
Complete inspection history, instantly available, optional access via project portal.
SHEV, fire doors, hold-open devices, fire dampers in the same visit — one invoice process.
On defects, direct offer for remediation — one contact for inspection and repair.
