Apollo Fire Detectors Discovery Heat — Fire Detection Systems. As a Heat Detector, it is normally installed in accommodation, machinery, cargo-related or service spaces connected to the vessel fire-detection loop or zone. In that role, its primary purpose is to detect smoke, heat or flame and initiate an alarm at the fire-detection panel. Smoke, heat and flame detectors use different sensing principles and are selected for the protected environment, so test methods and susceptibility to contamination differ. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.

Perform functional testing with the approved method for the sensing principle and verify correct alarm location at the panel. Investigate recurring nuisance alarms rather than disabling the detector. Refer to the manufacturer documentation for the exact figure for testing and replacement criteria.

Makers and authorised dealers rarely quote marine equipment without the vessel. With these details we can check availability and prices faster; without them we may have to ask first, which can cost a few days. If you cannot share the vessel, a photo of the equipment’s rating plate does the same job — send it as a reply to our confirmation e-mail.
