Environmental Monitoring Card 9

Sensor Selection

Dry contact

sensors

The Environmental Monitoring Card may be used with any dry

contact closure sensors. The card’s sensor inputs monitor

circuits that have no voltage potential of their own.

Normally open

and normally

closed sensors

Any normally open (NO) or normally closed (NC) dry contact

sensor may be used with the card. Such sensors include:

• magnetic contact switches

• window foils

• tamper switches

• heat detectors

• water sensors

• pressure sensors

Detectors that

need power

The card provides 12 VDC at up to 60 mA at pins 1 and 2 of

the sensor zones connector for sensors that require power.

These include:

• passive infrared (body heat) detectors

• smoke sensors

• photo relay detectors

For more

information

For a list of supported sensors, go to the APC Web site at

www.apc.com/support. Follow the link to Knowledge Base

and enter sensors in the search box at the bottom of the page.

You may also call APC Customer Support at a number on the

back cover for more information.

Warn

Connecting the card’s sensor inputs to any circuit

other than a dry closure type will void the

warranty and may result in damage to the card.
