Replacing Detectomat detectors: types, successors and bases
Which Detectomat detectors manufactured from 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.
Detector age
How old is the detector – how long has it been in operation?
- Detectomat: Rating plate with item number and date of manufacture or date code. The commissioning date can be found in the logbook and records.
- Logbook and reports (decisive): The operating time counts from the commissioning of the detector. The date is recorded in the logbook, in the commissioning or acceptance report or in the last replacement report. This gives the years and months in operation.
- Type plate on the detector: The label (usually on the underside or side of the detector, visible after twisting it out of the base) shows the type, serial number and date of manufacture or a date code (e.g. year/calendar week). If no commissioning date is documented, we take the cautious approach of calculating from the date of manufacture.
- Reading out via the panel: With many addressable loop detectors, detector data such as serial number, date of manufacture, degree of contamination and – depending on the system and software version – operating hours can be retrieved via the panel’s operating unit or programming software. We do this during the survey using your programming file.
This determines the replacement interval under DIN 14675: as a rule 5 years, or 8 years for detectors with contamination compensation and testing in accordance with the manufacturer’s specifications – details under Deadlines & standards. Send us a photo of the type plate and we will determine the age for you.
Identify
Which Detectomat detector do you have installed?
Detectomat detectors are available as addressable loop detectors for the system Loop3000 (type designation PL 3200 … or PL 3300 …, control panels e.g. dc3500) and as conventional detectors of the series CT 3000. The type designation and the five-digit item number are shown on the rating plate on the detector. Since 2025, several detectors have been available in a new “Version 2025” with a new item number – according to Detectomat, 100% compatible with the predecessor.

No longer available
Older Detectomat detectors: successors and bases
The addressable loop detectors of the PL 3200 series have been discontinued and are being replaced by the PL 3300 series. For the PL 3300 and CT 3000 series, Detectomat replaced several detectors in 2025 with a new version with a new item number – according to Detectomat 100% compatible; the base remains.

Detectomat bases: when a new base is needed
According to Detectomat, the base SDB 3000 fits all detectors of the CT and Loop3000 series; the base SDBB 3000 additionally has a bridge that keeps the loop closed when the detector is removed. When the detector is replaced with the same type or the Version 2025, the base remains.

Important
Before ordering
- Check the panel: Whether Loop3000 or CT 3000 detectors can be operated on your fire alarm control panel depends on the panel (e.g. dc3500), software version 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.
- EN 54 tested (as of 19.10.2026): All Detectomat detectors listed as available are certified to EN 54-5 or EN 54-7 (multi-criteria detectors with CO additionally to EN 54-26/-29/-30). The detectors that are no longer available were approved under the EN 54 or VdS rules applicable when they were introduced; since 2008, CE marking to EN 54 has been mandatory for new detectors – which is why we only list currently certified types as replacements.
- 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 Detectomat item numbers (source: detectomat.com and dc3500 installer manual, last updated: 18.10.2026).
- Image credits and trademarks: Product images © detectomat. The images serve solely to identify the detectors. Brand and product names are the property of their respective owners. Further information in the Legal notice.
