APC SmartSlot Series - Manual (Page 11)

5. Sensor Selection
Measure-UPS II may be used with any dry contact closure type sen-
sors. The Measure-UPS II sensor inputs are designed to monitor cir-
cuits that have no voltage potential of their own. Connection of
Measure-UPS II sensor inputs to any circuit other than a dry closure
type will void the warranty and may result in damage to Measure-UPS
II.
In general, any normally open (NO) or normally closed (NC) dry con-
tact sensor may be used with Measure-UPS II. Such sensors include:
• Magnetic contact switches
• Window foil
• Tamper switches
• Heat detectors
• Water sensors
• Pressure sensors
Additionally, Measure-UPS II provides a source of power for those
detectors that need power. These types 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.
