ERRS - Electronic Remote Release Systems

ERRS LAD - List Angle Detection

Features

• Automatically release of units at a specified degree of list.
• Different configuration of the list angle and different activation sequences of outputs are available.
• Can also release units manually by local or remote push button.

Especially suited for

Vessels with increased risk of capsize due to working conditions such as fishing vessels and workboats.
With current float-free release systems on the market, safety equipment is released first when it reaches a depth of 1,5 to 4 metres. When a ship or a vessel capsizes without sinking, there is therefore a risk that liferafts and EPIRBs are trapped under the vessel, or never released at all if not submerged to a sufficient water depth.

With List Angle Detection (LAD) liferafts and Epirbs can be automatically released at a specified degree of list when a vessel capsizes. The released safety units reach the surface before the ship flips around, significantly reducing the risk for it to be trapped or entangled in constructions on deck.

In- and outputs

ERRS LAD can be controlled from several remote release positions or automatically by a HPS (Hydrostatic Pressure Switch) or a water sensor. Output number two is activated automatically 2 seconds after output number one has been activated as a standard configuration. For activation of relay outputs the unit has to be configured for this function and an ERRS Addon modul (HM-0464) is needed.

System check

ERRS LAD automatically performs a system check once every hour. The system check monitors battery, emergency power voltage, ERU circuits and the wiring to an external activation switch. The battery condition is checked every 24 hours. If the system check detects a deviation an alarm message will appear on the LED indicator and the alarm output is activated. It is possible to initiate a manual system check which is useful at raft service.

Power supply

ERRS is powered by the ship’s emergency power supply. Each control panel is also equipped with a back-up battery to ensure operation in all emergency conditions.
