Contact Sensors
Selecting | To monitor circuits that have no voltage potential of their own, | |
sensors | you can use any normally open (NO) or normally closed (NC) | |
| dry contact sensors. These sensors include: | |
| • | Magnetic contact switches |
| • | Window foils |
| • | Tamper switches |
| • | Heat detectors |
| • | Water sensors |
| • | Pressure sensors |
| Note: Connecting sensor inputs to circuits other than dry | |
|
| closure circuits voids the warranty and may damage to |
|
| the unit. |
| To monitor sensors that require power, the Environmental | |
| Monitoring Unit provides 12 VDC at up to 60 mA at pins 1 and | |
| 2 of the Sensor Zones connector. These sensors include: | |
| • Passive infrared (body heat) detectors | |
| • | Smoke sensors |
| • | Photo relay detectors |
| For more information on types of sensors you can use with the | |
unit, call APC Customer Support at a number listed on the back cover of this manual.
