WARNING!
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 oper-
ation. Solvents in the paint may also cause an alarm condition to occur.
WARNING!
Protect the device from extreme vibration. Do not mount the sensing head in direct sunlight, since this
may cause the sensor to overheat. A stainless steel sunshield is available for the device to protect it
from extreme environments.
CAUTION!
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 unit 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 wrench on the hex nut in the sensor neck to install or remove the sensor.
Do not apply torque to the two sensor legs.
Optional Junction Box Instructions:
If installing the device on a junction box, verify that the junction box area classification is appropriate
for the installation environment. Two options are available for MSA junction boxes:
•
Powder-coated Aluminum
•
316 Stainless Steel
A stainless steel mounting plate is included with either junction box to ensure that there is sufficient
clearance from the installed surface (see fig. 5 and 6).
