CHAPTER 2: INSTALLATION
OPERATING ENVIRONMENT
The Sensaphone 2800 should be mounted and operated in a
clean, dry environment. Locate the unit in a central location to
insure that all wireless sensors are within range of the 2800.
Do
not install the unit inside of a metal cabinet as this will prevent
it from communicating with any wireless sensors. 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 2800
The NEMA-4 enclosure 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.
