CHAPTER 2: INSTALLATION
OPERATING ENVIRONMENT
The Sensaphone 1800 should be mounted and operated in a clean,
dry environment. The unit is microprocessor-controlled and as a
result it should not be installed near devices that generate strong
electromagnetic fields. Such interference is typically generated by
power switching equipment such as relays or contactors. A poor
operating environment may result in unwanted system resets and/or
system lockup. The temperature range the unit can operate in is
32°F to 122°F (0°C to 50°C). If the unit needs to operate below
freezing, a heater should be installed nearby.
Mounting the 1800
The NEMA-4 enclosure housing the 1800 comes with hardware for
wall or panel mounting. The four tabs are attached by screwing the
round bubble-end of a tab to each of the four rear corners of the
enclosure. Then mount the unit in a position that allows easy access
to the Zone terminal block and keypad. Also, there must be a power
outlet and telephone jack close to the unit.
