WARNING!
• Mount the device with the sensor inlet fitting extended horizontally from the main enclosure (→
reduce the potential for the build-up of particulate or liquid matter on the monitor's optical surfaces.
• Insert gasket between IR sensor conduit nipple and display enclosure, and compress 3.0 to 3.8 mm to ensure
proper Ingress Protection (→
• Do not paint the device. If painting is done in an area where a sensor is located, exercise caution to ensure paint
is not deposited on the sensor. Such paint deposits could interfere with the device operation. Solvents in the paint
may also cause an alarm condition to occur.
• Protect the device from extreme vibration.
• Do not mount the sensing head in direct sunlight without a sunshield since this may cause the sensor to overheat.
Failure to follow these warnings can result in serious personal injury or death.

NOTICE
During sensor installation or removal, do not use any tools or apply excessive force to the two legs that support the
unit's reflectors. Applying force to the legs can permanently damage the monitor.
MSA recommends that the device's environmental guard should be installed on the sensor at all times. If the device is
to be operated without the guard, frequent checks must be made to ensure particulate or liquid matter has not collected
on the windows.
1. Use a 36 mm wrench on the hex nut in the sensor neck to install or remove the sensor.
○ Do not apply torque to the two sensor legs.
