The AL-8000 alarm monitor provides an intelligent networked solution for the monitoring up to 32 different alarms.The diagram (right) shows a typical system layout. The system consists of the AL-8000 display controller (as seen above), up to four AL-100 units and one (optional) repeater display. Communication to these is via a 2-wire network cable with a maximum cable length of 1000 meters.
AL-8000 DISPLAY CONTROLLER: Is the master display unit.
- Visual & audible alarm for any fault condition.
- 4 x overrides (engine running overrides for engine alarms).
- 8 inputs have programmable delays (5 seconds to 10 minutes).
- All alarms tone programmable (with tone or without tone or repeating tone).
- Alarms are name programmable e.g. (High Bilge) (Engine Room Fire) (Oil Pressure) (Water in Fuel).
AL-100: Input module:
- Eight inputs.
- Each input can be set for normally open & closing to +vdc on fault
- 2k2 line resistor for supervised line
- normally open & closing ground on fault
- normally ground & opening on fault
- One relay output = 3 amp inductive:closes on any fault.
RD-800:
The RD-800 Repeater Display is an optional extra and may be connected
anywhere on the vessel for convenient monitoring.
