Key Features
- Sensing Technology: Uses a photo-electric light-scatter chamber measuring both forward- and back-scattered light to respond to black and white smoke.
- False Alarm Reduction: Includes internal transient-rejection and smoke-confirmation algorithms to filter out non-fire sources.
- Sampling Rate: Samples for smoke once every 4 seconds.
- Operating Voltage: 8.5V to 33V DC.
- Operating Range: Designed to work from -40°C to +70°C and tolerate high humidity.
- Compatibility: Commonly paired with specialized bases like the TimeSaver Base and connected to compatible fire detection control panels (such as Fireboy panels).
Key Features and Specifications
- Part Number / Reference: Typically ORB-MB-00001-MAR (standard with continuity switch) or ORB-RB-40004-MAR (relay version).
- Design: Open working area with shaped fixing holes and multiple fixing centers for simple ceiling or bulkhead mounting.
- Terminals: Grouped, captive terminal screws (which do not fall out during wiring) with a built-in cable stripping guide.
- Marine Durability: High salt-mist and 98% relative humidity tolerance, vibration-resistant, and built with corrosion-resistant technical plastics.
- Alignment & Locking: Features an LED alignment mark to keep detector orientation uniform, a mechanical detector locking mechanism, and a continuity link for testing zone wiring prior to final commissioning.
- Approvals: Certified to meet Marine Equipment Directive (MED) standards and classified by major marine authorities like Lloyd’s Register (LR), DNV GL, and ABS.
