Detectors
Types, successors and bases
Which detectors from year of manufacture 2000 onwards must be replaced, what is still available, which detector replaces older types and when a new base is needed – with the manufacturers’ order numbers.
Select the manufacturer of your fire alarm system. You will find the type designation or article number on the detector’s type plate.

Important
Before ordering
- Check the panel: Whether a replacement detector can be operated on your fire alarm control panel depends on the panel, loop or line technology and programming. We check this using your detector list and programming file.
- Replacement interval: Smoke and multi-sensor detectors after 5 years at the latest, or after 8 years with automatic contamination compensation and testing in accordance with the manufacturer’s specifications – details under Deadlines & standards.
- Change of detector series: New bases, different detector types or a changed number of detectors may constitute a significant modification – see expert inspection and fire brigade.
- Installation by a specialist company only: Replacement and repair of detectors in fire alarm systems required under building law are part of maintenance and are reserved for a specialist company certified to DIN 14675 – even if you only buy the detectors from us. Details under Legal situation.
- Order numbers are given on the manufacturer pages, each with source and date.
- Trademarks: All manufacturer, brand and product names mentioned are the property of their respective owners and are used solely for identification. Image credits are given on the manufacturer pages and in the Legal notice.
