GEIST™ POWER FAILURE SENSOR
Quick Installation Guide
VM1055/590-2254-501A 1
Part Number:
PFS
Description
The Power Failure Sensor (PFS) is
used to monitor voltage presence
(grid/city power) on a circuit
through the I/O ports of a remote
environmental or power +
environmental monitor. If voltage
drops to zero, the monitored I/O
reading drops below 10.
NOTE: To monitor the loss of ‘grid-
supplied’ power, connect the
PFS-100 directly to that power
source before any UPS systems.
NOTE: In order to monitor and
report the PFS signal state during a
power loss, the remote monitoring
unit itself, as well as any switches
or routers within the data path of
the unit, must be backed up by
UPS power. If any of these units
lose power during a power outage,
appropriate remote alarm reporting
cannot take place.
Installation
1. Using only an approved AC
adaptor, plug the adaptor into
the desired ‘grid-supplied’
power location. Do not plug the
adaptor into the PFS-100
sensor body yet.
2. Route the sensor body wire
with the two stripped ends to
the remote monitoring unit.
Connect the ends to the I/O
port on the remote monitoring
unit. The solid black wire
connects to Common (-) and
the striped black wire connects
to the desired Input (1, 2 or 3).
3. Plug the approved AC adaptor
into the PFS-100.
NOTE: During initial setup, one
PFS-100 LED turns on and one
flashes for approximately 35
seconds. After that time, a third

LED turns on and the flashing
LED stays solid on, indicating
that the sensor is ready.
4. Use the remote monitoring unit
to test the sensor. With the
PFS-100 plugged in, the I/O
reading is >50. When the
PFS-100 is unplugged or the
circuit loses power, this value
drops below 10.
5. On the remote monitoring unit,
click the Configuration icon,
change the sensor label and
click Save. Complete this step
before installing additional
sensors.
6. As data is analyzed over time,
you can determine steady state
conditions and set alarms
accordingly.
