RAP-2 Alarm Panel

RAP-2 Alarm Panel provides a visual and audible alarm to alert that ozone levels are unsafe. The RAP-2 can be placed in a separate room than the primary gas sensor, or in the same room for an extremely visible alarm.


The RAP-2 Remote Alarm Panel is for alarming when signals from gas monitors reach preset limits or set-points. The alarms are a red strobe light and a loud audible alarm.

The RAP-2 also outputs its input signal in 4-20 mA form for building automation systems and other applications requiring long signal paths. The RAP-2 is powered by 14-30 VAC or DC. This remote alarm panel was designed for use with the Eco Sensors C-21C-30ZXEE-2, and OS-4. However, it can be used with most any gas monitor. 

The RAP-2 is extremely versatile offering many features that can be useful for a gas monitor control system.


The RAP-2 can be used for the following:

  • Remote visual alarm (user settable alarm point)
  • Remote audible alarm (user settable alarm point)
  • Convert voltage input 0-2 VDC to 4-20 mA output
  • Provide fail safe dry relay contacts for external alarm (user settable alarm point)
  • Power monitor 14 - 30 VDC from the RAP-2
  • Can operate from 14-30 VDC or 14-30 VAC
