3.3. Wiring Alarm Output (Analog Signal)
The MGS-250 provides an analog output signal that is proportional to the
level of gas detected.
NOTE:
No jumpers or hardware switch settings are required
to configure the analog output. This is done electronically
from the front panel display.
Connect two 18 to 20 AWG wires to terminal block positions 5 and 6 (see
Figure 10), noting ground and signal polarity per Table 6.
