#Stickers or #labels placed next to fire detectors on a vessel are not decorative — they are an important part of the #safety and #maintenance system. Here’s why they are needed:

1. #Detector identification (address/number)

Every fire detector has a unique address, which appears:
• on the fire alarm control panel (#FACP)
• in fire zone drawings
• in the loop list / address list

The sticker helps crew and inspectors quickly identify:
• the zone,
• the detector number in the loop,
• the type (smoke / heat / multi-sensor).

2. Troubleshooting and maintenance

When the panel shows something like:

FAULT: Detector 2/034 – Cabin 312
or
FIRE: LOOP 1, DETECTOR 018

the engineer can go to the actual location and verify the correct detector using the sticker.
Without labeling, finding one specific detector among many identical ones is almost impossible.

3. Class requirements (#DNV, #LR, #ABS)

Classification societies require that all #fire detectors be properly marked so:
• the correct detector can be found quickly in case of alarm or fault,
• inspectors can compare real installation with #drawings,
• confusion during repairs is avoided.

4. Testing convenience

During annual fire alarm testing (#FAR / FACP test):
• the technician walks through the vessel with a #loop list or tablet,
• activates each detector,
• checks if the address shown on the panel matches the label.

5. #Shipyard and contractor work

During upgrades or new installations:
• labels help identify which loop the detector belongs to,
• which #SCI is associated with it,
• and the order of addresses in the loop.
