2.7 Interfacing Macurco Sensors

All Macurco CO, NO2 and combustible gas sensors with current loop outputs may be used with the DVP-120.
Data sheets for the Macurco sensors listed in Table 2-8 are provided as an appendix to this manual.

Power connections to Macurco sensors used with the DVP-120 are polarity-insensitive, since a bridge rectifier
is connected to the power input terminals. All sensors used with the DVP-120 panel employ screw clamp
terminal blocks for power and signal connections.

Polarity of the current loop connections is marked on the printed circuit board of the sensor.
