CORA CS1000 Long Range Door Sensor

Long-range, low-power door and window sensor supporting LoRaWAN or Coralink wireless protocols. Ideal for applications in smart building, home automation, metering, and logistics.

Getting Started

The CS1000 is a long-range, low-power door and window sensor supporting LoRaWAN or Coralink wireless protocols. The sensor provides configurable real- time alarms or regular reported statistics. The sensor can be readily attached to doors, windows, or drawers and other equipment. The base unit detects the presence of a strong magnetic field (provided by the included magnet). Small and low profile, the sensor can be used for a wide variety of applications where magnetic triggered events or counting is required.

What’s In the Box
The CS1000 door sensor package contains the following:

• Door Sensor
• Magnet

The door sensor is comprised of the main unit, the sensor, and a magnet. Each of these units have double sided tape to permanently attach the to smooth surfaces. See Installation for additional details and to learn more about attaching the sensors.

Attaching to the Network
The device is shipped in a factory hibernate state. Once the sensor is removed from the packaging, it can be activated by pushing the SET button once. The device will activate, blinking orange four times and begin issuing join requests. The LED status indicators is shown in the figure below.

Figure 2 – CS1000 LED Status Indicators
Periodically, the device will blink red twice while attempting to join. Assuming the device is properly registered on an available network and in range, it should connect. It will blink green four times to indicate it has joined. Once joined, the device can be tested by moving the magnet away and near the main unit sensor. By default, the device will generate open and closed alarms to notify the application that the events have occurred. If the magnet remains away too long from the main sensor unit, time alarms may also be issued.
Note: If the device has not joined within a few minutes, the LED will stop blinking, though it will continue try to join: ten times in the first hour, then longer intervals over the first week until finally attempting once every 12 hours. This is done to conserve battery power when the network is not available for long periods of time. You may reset the join schedule by performing a Network Reset on the device, see User Interface. To learn more about the capabilities of the CS1000, see Configuration and Integration.

User Interface

Reset / Status Button
The CS1000 user interface is comprised of the LED status indicators (Figure ) and the button shown below. Pressing the button quickly, will indicate the current network status discussed previously.

Figure 3 – Performing Network or Factory Reset on the Door Sensor
Holding the button will perform a network or factory reset:

• Network Reset – Press and hold the key button for 10 seconds, but less than 25, then release. The device will reset all LoRaWAN Settings which do not affect device operation and reboot. Following reboot, a reset event uplink (confirmed) will be sent upon rejoining the LoRaWAN network.
• Factory Reset – Press and hold the key button for > 25 seconds, then release. The device will reset all parameters to factory defaults. Following reboot, a Factory Reset event uplink (confirmed) will be sent upon rejoining the LoRaWAN network.

Status Indicators
A single button press will indicate the network status. The following table summarizes all the LED indicators.

LED Status

Fast Red Blink Two (2) Times| Not Joined
Fast Green Blink Four (4) Times| Joined
Slow Red Blink Two (2) Times| Joining Network
Slow Green Blink Four (4) Times| Joined Network

Network status blink occurs up to 50 times. Single button press will resume status blink for another 50 cycles.
About LoRaWAN
LoRaWAN is a low-power, secure, wide area (LPWAN) networking protocol designed to wirelessly connect devices to the internet in regional, national, or global networks. To use the CS1000 Door Sensor, wireless connectivity to an internet- connected LoRaWAN gateway is required.
For more information about LoRa and LoRaWAN visit the LoRa Alliance webpage: https://loraalliance.org/.
Terminology

• Message sent from the Door Sensor to the network are referred to as “uplink messages” or “uplinks”.
• Messages sent to the Door Sensor from the network are referred to as “downlink messages” or “downlinks”.
• Both uplink and downlink messages may be of either “confirmed” or “unconfirmed” type. Confirmed messages are guaranteed to be delivered but will consume extra wireless bandwidth and battery life. These mechanisms are analogous to TCP (confirmed) vs UDP (unconfirmed) protocols used for IP networks.
• Before a device, such as the CS1000 Door Sensor can transmit messages using LoRaWAN it must go through a “join” process. The Join process involves key-exchange with the cloud-hosted network provider (The Things Network, Helium, etc.) and is defined in the LoRaWAN protocol standard. If connectivity is lost due to RF interference, power loss or other temporary internet outages, the device will need to rejoin the network prior to being able to transmit messages. This process happens automatically but is managed in a battery-efficient manner and may take significant time.

Installation

1. The sensor and magnet are very difficult to relocate after being affixed to the mounting surface. Test the sensor and magnet location before affixing the device to the surface. Use masking or painter’s tape to secure the sensor and magnet to the surface (align the semi-circle on magnet with the semi-circle on sensor). Once the sensor and magnet temporarily are mounted, test it to ensure that generates open and closed alarms .
2. Be sure the installation gap between the sensor and magnet is within 0.4 inch and the semi-circle on the magnet is aligned with the semi-circle on the sensor body when closed.
3. Avoid exposing the sensor to strong impacts of vibration. The sensor body should be mounted on the fixed part (frame) of a door or window, while the magnet should be mounted to the movable part of the door or window.
4. The sensor operates with a magnetic reed-type switch. Take care to install away from other strong magnetic fields or spurious alarms could occur.

Attaching the Door Sensor and Magnet

1. Clean the Installation Area:
2. Remove the protective layer from the rear of sensor and place it in the desired position (fixed part of door or window) and press firmly for at least 5 seconds.
3. Remove the protective layer from rear of magnet and align the magnet semi-circle with the body semicircle, press firmly for at least 5 seconds.

Alarms and Reports

The CS1000 Door Sensor has three standard alarm messages enabled by default:

• Door Open Alarm – Sensor changed from closed state to open state.
• Door Closed Alarm – Sensor changed from open state to closed state.
• Door Open Alarm Timeout – Door has not closed within the specified time period. This alarm is optional and must have the interval and count configured prior to use.

Additionally, statistics can be enabled providing regular reports of sensor event activity:

• Door Open Counter
• Door Closed Counter
• Lifetime Door Closed Time
• Lifetime Door Open Time
• Min/Max Door Closed Duration
• Min/Max Door Open Duration

Statistics are stored in non-volatile memory and will persist through a battery change or dead battery. Both the statistic reporting and alarms can be configured remotely by sending downlink messages. The sensor has a periodic Heartbeat / Battery-status message that must be sent to maintain LoRaWAN network connectivity and provide battery status information. The default period for this message is 60 minutes and may be configured between two (2) minutes minimum and 48 hours maximum.

Reset Notifications
After any type of device reboot a Reset Event uplink message (confirmed) will be sent.
Firmware Version
The firmware information can be retrieved via sending a downlink command. See Configuration and Integration for details.

Replacing the Batteries

1. Remove the housing screw using a small Phillips screwdriver.

2. Push the sensor body upwards and gently remove the sensor by pulling it outwards.

3. Remove old batteries and dispose of in accordance with your local regulations.

4. Install two new AAA batteries
   Note: Do not mix old and new batteries!

5. Reassemble the sensor and tighten the screw.

6. Verify the sensor is functioning. The sensor will rejoin the network prior to communicating.
