3600I 1.3 1.4 FEATURES AND BENEFITS • Detection Range: Up to 215 ft. (65m) for a 1 ft2 (0.1m2) n-heptane fire. • Ultra High Immunity to False Alarms: See Table 4 on page 10. • Advanced Digital Processing of the Dynamic Characteristics of Fire: Flickering, threshold correlation and ratio. • Multi IR Channels: Between 3-5 microns • Field Programmable Sensitivity: Four ranges to avoid zone crossover. • Built In Test (BIT): Manual and Automatic (see Built-In-Test (BIT) on page 15).
3600I The IR3 technique utilizes few infrared sensors, each sensitive to its own wavelength range. The first sensor is sensitive to wavelengths within the emission peak of hot CO2. The other two sensors are sensitive to wavelengths above and below this peak. The fourth IR sensor is sensitive to a different band within the emission peak of hot CO2. In the event of fire, the signal measured in the first sensor is significantly higher than those measured in the second two sensors.

The detector statuses are listed in Table 6.
3600I 1.5.5 OUTPUT SIGNALS Outputs are available according to the default configuration or the wiring options selected for the 3600I IR3 Detector. Determine the outputs for your model according to Table 7.
3600I 1.5.6 DETECTOR STATUS The possible detector function statuses are listed in Table 8. A more detailed fault analysis can be seen via HART or RS485. Table 8: Detector Status Status Normal BIT Warning Alarm Latched Alarm (Optional) BIT Fault Fault Description Normal operation. Built-In-Test being performed. Fire detected - changed to Warning (pre-alarm state). Fire detected - changed to Fire Alarm state.
3600I 1.5.6.1 OPTIONAL LATCHING Alarms are set as non-latching by default. However, the detector includes a latched alarm output capability, which operates according to the programmed function. If selected, upon detection of a fire, the detection signal is latched until a manual reset is performed (disconnecting the power supply or performing a manual BIT (see Manual BIT on page 16).
3600I Response to Fault Indication If a failure is found, the detector indicates by: • Fault relay: • Opens in wiring option 1, 2, and 4 • Closes in wiring option 3 and 5 • 0-20mA: indicates Fault (0mA or 2mA) in wiring option 1, 2, 3 • LED – Yellow flashes (4 Hz) Correcting the Fault The fault indications remain until the detector’s power is removed. The fault indications return if the fault is still found when power is restored. 1.6.
3600I 1.6.2.2 AUTOMATIC BIT The detector automatically performs a BIT every 15 minutes. A successful BIT sequence does not activate any indicator. The results of a successful and unsuccessful BIT are listed in Table 10 and Table 11.
