Measure-UPS II ma
be used with an
dr
contact closure t
pe sen-
sors. The Measure-UPS II sensor inputs are desi
ned to monitor cir-
cuits that have no volta
e potential of their own. Connection of
Measure-UPS II sensor inputs to an
circuit other than a dr
closure
t
pe will void the warrant
and ma
result in dama
e to Measure-UPS
II.
In
eneral, an
normall
open (NO) or normall
closed (NC) dr
con-
tact sensor ma
be used with Measure-UPS II. Such sensors include:
• Magnetic contact switches
• Window foil
• Tamper switches
• Heat detectors
• Water sensors
• Pressure sensors
Additionall
, Measure-UPS II provides a source of power for those
detectors that need power. These t
pes include:
• Passive infrared (body heat) detectors
•Smoke sensors
• Photo relay detectors
Measure-UPS II provides 12 Vdc at up to 60 mA at pins 1
and 2 of the Sensor Zones connector for sensors that require power.
