Liao Hai Ferry
- Products Used:200 Discovery Marine detectors, deckhead mounting box
- Installer:Shanghai Jin Zhou
The Liao Hai is a roll-on-roll-off ferry. Measuring 115m long
and 21m wide, it has the capacity to transport 650 people and
approximately 100 lorries. The China Tian jin XinGang shipyard
awarded the contract to supply an intelligent fire detection system
for the Liao Hai, a new roll-on roll-off ferry, to Apollo's local
representative Shanghai Jin Zhou.
The fire detection system includes around 200 Apollo intelligent
detectors, including multisensors, which have been approved for
marine applications by the China Classification Society following
additional tests specific to the marine environment.
Most of the detectors used on the vessel have been fitted using
Apollo's Deckhead Mounting Base. This is a robust back box, made
from either aluminium or polycarbonate, for use with standard 100mm
detector bases. Fixing points are external, enabling a seal to be
maintained and therefore providing protection against contaminant
ingress into the rear of the base. These boxes are particularly
useful when securing bases to rough surfaces or in areas where
there may be dripping water.
The Liao Hai fire detection system allows a two minute delay in
the event of an alert so that an incident can be investigated. If
the alert is genuine, the system then proceeds to raise the alarm.
Apollo zone monitors with inbuilt isolators have been installed to
enable the fire detection system to interface with other critical
equipment on board. A fire alarm triggers a preset sequence of
events to ensure that passengers can be evacuated safely. Actions
include operating fire doors and dampers and closing down the air
conditioning to the passenger and car decks to prevent the spread
