4. Technical characteristics
20422 - 16594 - 16594.B - 14422:
• Supply voltage: 230 V~ ±10% 50-60 Hz
• Sensitive element: tin dioxide semiconductor
• Setting: sealed with thermal compensation
• Setting threshold:
- 100 ppm for at least 15 minutes
- 300 ppm for at least 15 seconds
Once activated, the alarm remains in operation for concentra-
tions of carbon monoxide (CO) exceeding 100 ppm
• Terminals L - N: supply voltage 230 V~ ±10% 50-60 Hz
• Terminals NO - C - NC: clean contact changeover output relay
for connection to additional alarms and solenoid valves, (terminals
NC - C if normally closed; terminals C - NO if normally open):
- NO 5 A 230 V~
- NC 2 A 230 V~
• Blowout detectors:
- with piezoelectric buzzer 85 dB for 1 m
- visual with front LEDs (green

16594.S - 16594.S.B:
• Supply voltage: 12-24 V~ 50-60 Hz and 12-24 V d.c. (SELV)
• Sensitive element: tin dioxide semiconductor
• Setting: sealed with thermal compensation
• Setting threshold:
- 100 ppm for at least 15 minutes
- 300 ppm for at least 15 seconds
Once activated, the alarm remains in operation for concentra-
tions of carbon monoxide (CO) exceeding 100 ppm
• Terminals + and -: supply voltage 12-24 V~ 50-60 Hz and 12-24 V d.c.
(SELV)
• Terminals NO - C - NC: clean contact changeover output relay
