516.850.053.E MX Digital Loop 850H Heat Sensor
CONDITION: NEW (UNUSED)
The 516.850.053.E 850H heat sensor measures the temperature and sends this to the 4100-6077AU MX Digital Loop Card in the 4100ESi fire alarm panel. The 4100ESi software can determine if an alarm or other condition, e.g., fault is present. The sensor contains a loop short circuit isolator that isolates a section of loop cabling if a short circuit is present (requires 4B-C base to be used). The sensor must be plugged into one of the following bases:
517.050.042 4B-C Continuity base
516.800.910 802SB Sounder base – Loop powered
516.800.911 901SB Sounder base – Externally powered
516.800.957 LPSB3000 Symphony Sounder base - Loop powered
516.800.958 LPAV3000 Symphony Sounder/Beacon base - Loop powered
Using the 4100ESi programmer, the sensor can be programmed for:
• Fixed temperature modes A2S, CS or Rate of Rise modes A2R, CR
• The LED to blink on poll or not
Note: Only when the 850H heat sensor is fitted to the 4B-C Continuity base is its in-built short circuit isolator used. When the 850H is programmed as a CS Fixed Temperature or CR Rate of Rise sensor, only the 4B-C base may be used.
• Input voltage (MX Digital Loop): 20 to 40 VDC maximum
• Quiescent current: 290µA
• Alarm current without remote LED: 3 to 3.3 mA Electrical characteristics at 25oC and at nominal supply voltage of 37.5V
