Answer:
The SS-LD-68-155 triggers an alarm at a fixed activation temperature of 68°C (155°F), supports zone runs up to 3,000 meters, and maintains a strict minimum bend radius of 50 mm. It operates at voltages up to 30 V AC and 42 V DC with a conductor resistance of approximately 0.05 Ohm/ft.
The Honeywell System Sensor SS-LD-68-155 is a digital fixed-temperature linear heat detection (LHD) cable designed for continuous thermal monitoring in industrial and commercial hazard areas. Key operational and mechanical parameters include:
- Alarm Trigger Temperature: 68°C (155°F) fixed activation threshold.
- Maximum Continuous Zone Length: Up to 3,000 meters (10,000 feet) per supervised circuit.
- Minimum Bend Radius: 50 mm, which must be maintained during installation to prevent core fracture or insulation damage.
- Electrical Ratings: Operating voltage rated up to 30 V AC and 42 V DC; conductor loop resistance of approximately 0.05 Ω/ft across the twisted pair.
- Capacitance & Inductance: Capacitance of 88 to 150 pF/m (26 to 45 pF/ft) and inductance of 540 to 1050 nH/m.
- Environmental Range: Rated for ambient operating limits between -40°C and +121°C, with non-condensing relative humidity handling from 90% to 98%.
- Spool Options: Factory lengths supplied on 100 m, 200 m, 500 m, and 1,000 m reels.
