The MS900 must be mounted in an area where
there is a clear, unobstructed path to the environ-
ment where the Transmitting PASS (man-down-
alarm) or SuperCELL (man-down alarm) may be
used. A typical location for the MS900 would be
near an unobstructed offi ce window or mounted
just outside an offi ce.
The MS900 should also be located as
far away as possible from other radio
equipment antennas to minimize any interfer-
ence.
This includes cell phone boosters, wifi , and
other 2-way radio equipment antennas. It is also
recommended to keep the MS900 a minimum of
six inches away from metal surfaces.
The power consumption of the MS900 is low -
typically 100 mA at +12 VDC.
A System Check of the MS900 can be done
by viewing the Receive LED located on the bot-
tom surface of the MS900. When a SuperCELL
or TPASS is turned On, Off, or by activating the
Alarm, the radio signal will cause the Red Receive
LED to fl ash several times - indicating signals are
successfully being received by the MS900.
Once the MS900 has been prepared for AC pow-
er, the unit may be plugged in. AC power connector
is a screw less Terminal rated for solid or stranded
wire from 14-22AWG. Wire should be stripped at
a 1/2”. Wires should be inserted by using a small
screwdriver to depress the lever and then insert-
ing the wire.
When the unit is plugged in to AC Power, the
AC Power Indicator glows (or fl ashes) Green -
indicating the system has AC Power and is ready
for operation. With loss of power, the AC Power
Indicator glows (or fl ashes) Red - indicating the
Backup-Battery System has been automatically
activated, keeping the MS900 ON and ready for
operation.
