.
1.13 Alarm Inputs
The ADPRO FastTrace Model 5020 has thirty external Alarm Inputs, all with selectable tamper detection
configurations (Model 5005 and Model 5010 have twenty). The camera setup options can be programmed to trigger
an alarm on detection of either a closed contact or an open contact condition on an Alarm Input. Alarm Inputs are
normally connected to alarm sensors such as door switches, passive infrared detectors, microwave detectors, vibration
sensors, electric field detectors, etc.
1.13.1 Driving the Alarm Inputs
For an alarm input to be recognised, the input device must hold a changed state for a period of time.
• For a valid closed contact, the total resistance, including wiring resistance, must be below 150 ohms
• For an open contact to be valid the resistance presented at the Alarm Input must above 2,500 ohms
The Alarm Inputs and numbering for all channels is shown in Figure 1-7. Note that the Alarm Input ground
connections are not isolated from the chassis ground.
Figure 1-7 - Alarm Connector Pinouts
Wire connections from the alarm switches are made by using the screw terminal contact strips supplied with the
ADPRO FastTrace. For ease of installation, the screw terminal blocks slide over the connector pins when the wiring
is complete.
