Digital-Display - AMS S/200-C Aufstell-, Montage- Und Bedienungsanleitung

Note:
• The mute function cannot be activated if the carbon monoxide concentration
exceeds 300 ppm.
• The mute function can only be used once during an ALARM phase, i.e. the
acoustic alarm can only be suppressed once for a period of 5 minutes.
Returning to normal mode
The alarm ends if the carbon monoxide concentration falls below the preset sensitivity
threshold. The green POWER indicator lights continuously.
Fault display
The CO alarm carries out a continuous self-test. A flashing yellow FAULT indicator and
the letter "F" on the display indicate the presence of a fault. In addition, two short signal
tones are issued per minute.
If the FAULT indicator is active, there is a possible malfunction of the device. Reset
the FAULT indication by disconnecting the power supply for 3 minutes. If the FAULT
indicator is still active after that, the device is defect.
In this case the CO alarm must be replaced or sent in for inspection!
Digital display
The carbon monoxide alarm is equipped with a digital display (LCD display) to show
the CO concentration. The unit shown on the display is parts per million (ppm). The
LCD display can show values between 30 and 999 ppm.
Normal mode
No values are shown if the ambient air is normal.
Activation of the LCD by the customer
Press the TEST button for 1-2 seconds to activate the LCD:
• The following display appears if the measured CO concentration is less than
- - -
30 ppm:
• The measured CO value is displayed if the concentration is greater than 30 ppm
The display remains active for 15 seconds.
Automatic activation of the LCD
If the CO concentration rises to a value of more than 50 ppm and the carbon monoxide
alarm goes into ALARM status, the digital display will be activated automatically.
The display remains active for as long as the alarm continues.
