Sensor Replacement
The Notis Quad's sensors must be fully functional in order to alert the user of the presence of toxic gas at a dangerous
level. Failed alarm tests could be an indicator of the Notis Quad needing a sensor(s) replaced.
1. Power off the device by touching and holding an Otis Instruments, Inc. distributed magnet against the
SUB
indicator label on the right side of the Notis Quad for four seconds to activate
SUB
.
2. Unscrew and remove the sensor housing cap.
