LINEAR DETECTOR
Part No. See table
Provides fire detection in the protected area; connects to the
CHECKFIRE 210 Interface Control Module via the Detection
Circuit Cable. See Figure 2-13.
Maximum total length of Linear Detector plus Detection Circuit
Cable is 750 ft (228.6 m). For example: If Detection Circuit
Cable is 50 ft (15.24 m), then Linear Detector could be up to
700 ft (213.4 m).
• Red color-coded connectors
• Two twisted spring steel conductors separated by a
heat-sensitive insulator
• Activation temperature rating of 356 °F (180 °C)
• Minimum bend radius, 2 1/2 in. (64 mm)
• Maximum installed continuous operating temperature:
250 °F (121 °C)
