Flood Alarm System
Arieckal flood alarm system detects flooding in watertight compartments and provides audio and visual alarms to alert the crew. It is easy to install, test and operate. It can be connected to the ship’s centralized instrumentation system. It confirms to IP 55, IP 67 and JSS 55555 specifications and is suitable for operation on 110V/240V 50 Hz AC supply. The system can be customized to activate a pump system to initiate discharge of water from the flooded compartment.
AFAS Architecture
Arieckal flood alarm system consists of sensors, local annunciator panels, main annunciator panel, repeater annunciator panels and low fire hazard cables.
Sensors
» Arieckal sensors detect flooding in underwater compartments and send signals to the main annunciator panel in case water levels rise beyond a predefined level.
» The different types of sensors are as follows;
› Single / Multi level float operated magnetic
reed sensor
› Single / Multi level pressure sensor
› Ultrasonic sensor, Vibrating fork sensor
» The main material of construction of the sensors is stainless steel. All the flood sensors confirm to IP 67 and JSS 55555 specifications.
» These sensors can be customized as per customer requirements. More than 800 type tested sensors have been supplied to naval ships.
Annunciator Panel
» Arieckal annunciator panels receive signals from the sensors and activate an audio-visual alarm to alert the crew. The annunciator panel has microcontroller-based PCBs fitted with LEDs and hooters which are enclosed in a die-cast aluminium box.
» The annunciator is available in 12 / 24 / 36 window units depending on the sensor density.
» The system is EMI/EMC tested and approved. The annunciator panels can be customized as per customer requirements.
» More than 75 type tested annunciator panels have been supplied to naval ships.
