Page 6: Intended Use
Introduction EpiSensor’s ZDI Digital Signal Sensor is intended to detect the open/closed status of switches, for example to detect when a door in a warehouse opens, and the percentage of time that it is open for. The ZDI reports the data through the wireless sensor network to the Gateway. -
Page 7: Configuring The Jumpers
Note: the single-channel version may use the same hardware as the dual channel version and so would also have a 4-pin terminal block. However, only the first channel (IN1) will be enabled on the ZDI-20 variant. Dry signals or pulses are not polarity sensitive, but Open Collector and Active signals or pulses are polarity sensitive. -
Page 8: Input Operation
Diagram showing ZDI-22 with IN1 configured for an Dry Pulse, and IN2 configured for a Active Pulse Input Operation This section describes the operation of the 3 different signal types. Dry Signal A dry signal can be thought of as a simple switch. Window alarm contacts or reed switches would be examples of such a connection. -

IN connector. The positive DC voltage representing the signal must be connected to the positive (+) terminal of the IN connector. Note: The Active Signal Voltage on the ZDI-20/22 should not exceed 40 Volts! The jumper should be in the “AP” position on the selector grid for monitoring Active Pulse/Signal outputs. -

Check the power supply, and if the problem persists, contact EpiSensor support. Alt LED The Alt LED will flash when data is transmitted or received on the ZigBee wireless network. For mains powered nodes, it will always be active - but for battery powered nodes, it will only be active when in Command Mode. -
Page 11: Mode Button
Mode Button The following options are available with Command Mode. The button should be pressed and then released to register a valid button press. If no further button presses are made, the device will terminate “command mode” 4 seconds after the last button press. Press Description Send a PING message disable any active Install Mode or Range Test Mode. -

ZDI has been isolated from any high voltage supplies. Please consult the safety notes at the start of this user guide for more information. Important Safety Note EpiSensor equipment should be installed, operated, serviced and maintained only by qualified personnel. There are no user-serviceable parts inside the ZDI enclosure, and it should always be isolated from mains voltages before opening the enclosure lid. -
