AHD 414A Alarm / Safety System

Product catalog summary

Overview: The AHD 414A is an approved alarm and safety system designed for maritime use, adhering to guidelines from classification societies such as GL, LR, ABS, and BV. It is a compact panel installation unit that monitors sensors, switches, and contacts, offering flexibility and customization to meet individual requirements.

Specifications: The system includes 10 free binary inputs for alarms and status notifications, with time-delayed alerting capabilities. It features a horn relay and three programmable group relays, a serial interface, and inputs for external acknowledgment and alarm release. The system is designed to monitor wire breaks in inputs and the group relay K1, which functions as a stop relay in safety systems.

Group Relay and Override Function: The AHD 414A has three group relays that can be assigned to alarms, functioning as initial or new value indicators. In safety systems, relay K1 operates as a normally open contact and initial value indicator. The override function allows for the prevention of engine stops under certain conditions, provided the override input is active.

Wire Break Monitoring: The system monitors all input channels and the output relay K1 for wire breaks, with visual indications provided by LEDs on the front panel.

Alarms and Notifications: Each input can be programmed for alarms or status notifications, with corresponding LED indicators. Alarms trigger an internal buzzer and activate the horn relay, while both alarms and status notifications can trigger group relays.

Acknowledgment and Reset: The system allows for acknowledgment of alarms via a frontside key or external input, changing blinking LEDs to continuous light. In safety systems, alarms remain active until a reset is initiated.

Lamp Test and Alarm Release: A lamp test function is available when no alarms are active. An input for alarm release or suppression is included, with the current condition indicated by an LED.

Technical Data: The system measures 144 x 144 x 53 mm, with a panel cutout of 138 x 138 mm, and weighs approximately 0.5 kg. It operates at temperatures between -10°C and +55°C, with a storage range of -30°C to +85°C. The power supply is 24 V DC, with a maximum current consumption of 200 mA. It includes 7 relay contacts and 13 LEDs for various indicators.

Approvals: The AHD 414A is approved by Germanischer Lloyd, Lloyd's Register, Bureau Veritas, and the American Bureau of Shipping.
