INTRODUCTION

WinDoor RF / WinDoor RF 915

WinDoor RF or WinDoor RF 915 from Zennio is a device that detects and notifies the opening and closing of doors and windows, communicating completely wirelessly by radiofrequency. This device is designed to be placed in the frame of doors and windows easily.

There are two different products for two different frequencies:

WinDoor RF (ref. ZRFWD) for 868 MHz.
WinDoor RF 915 (ref. ZRFWD915) for 915 MHz.

Hereafter this document will refer to WinDoor RF generically for both devices.

The most outstanding features of WinDoor RF are:

Door/window opening and closing detection with the possibility of configuring delays and periodic sends.

Radiofrequency communication (868 MHz o 915 MHz, depending on the model).

** Configurable transmission power.**

Alarms to indicate if there is tampering or low battery in the device.

Heartbeat or periodic “still alive” notification.

INSTALLATION

WinDoor RF is entirely powered through a battery. The communication with the other devices of the installation is carried out through the RF antenna that is incorporated inside.

Antenna RF
Programming LED
Programming button
Battery
Cover
Tamper button
Magnet

The main elements of the device are described next:

Programming button (3): a short press on this button sets the device into the programming mode, making the associated LED (2) light in red.

Note: if this button is held while plugging the battery, the device will enter the safe mode. In such a case, the LED will blink in red every 0.5 seconds.

Tamper sensor (6): allows detecting if the device enclosure has been tampered with.

To get detailed information about the technical features of this device, as well as on the installation process and on security procedures, please refer to the corresponding
Datasheet, bundled with the original packaging of the device and also available at www.zennio.com.

DEVICE PROGRAMMING

Once the battery is connected, downloading both the physical address and the application program will be possible. To do this WinDoor RF must be in an “active” state.
As long as there are no open/close events, the WinDoor RF remains in a low consumption idle state in which it does not respond to orders or reading requests, therefore, it is necessary to force it out of this idle state in order to perform the downloading.

WinDoor RF enters the active state for 1 minute in the following cases:

When pressing the programming button.

After power failure. Resetting the device will also cause the programming led to blink. After this flashing WinDoor RF enters an active state.

Note: If the programming LED does not light up when connecting the battery, perform a longer power failure (at least 30 seconds).

After the first window/door closing. The first time the closed window/door contact is detected since the last reset, there will be several flashes of the programming LED. After this blinking, WinDoor RF enters an active state.

START-UP AND POWER LOSS

During the start-up of the device, the programming LED will blink.

After each restart, the status of the window/door will be sent. In addition, if the tamper and battery alarms are enabled, the status of the 2 alarms will also be sent after the
restart.

CONFIGURATION

After importing the corresponding database in ETS and adding the device into the topology of the desired project, the configuration process begins by entering the parameters window of the device.

GENERAL

In the “General” tab all the functionality of the device will be configured, being its main function the sending of window/door state after each opening or closing.
In addition, two alarms will be available:

Tamper: notifies whether the device has been tampered with by removing its enclosure.

Battery: warns the user when the battery level is about to run out.

ETS PARAMETERISATION

From this screen, configuring the next parameters will be possible:

Transmission Power [Minimum / Low / Medium / High / Maximum]¹: allows to set the transmission power of the device.

Note: higher transmission power increases the transmission distance of the WinDoor RF but also shortens battery life.

Heartbeat (Periodic Alive Notification) [enabled/disabled]: incorporates a one-bit object to the project (“[Heartbeat] Object to Send ‘1’”) that will be sent
periodically with a value of “1” to notify that the device is still working (still alive).

Note: the first sending after download or bus failure takes place with a delay of up to 255 seconds, to prevent bus overload. The following sendings match the period set.

Window/Door Status Object [enabled]: enables the object “Window/Door (Status)” through which the notification of the window/door status is sent. After each state change, this object is always sent twice to ensure correct communication. Associated with this functionality, the following parameters are shown:

Object Polarity [0 = Open; 1 = Closed / 0 = Closed; 1 = Open]: sets the polarity of the object “Window/Door (Status)”.
Delay [0 …255][s]: allows setting a delay in seconds from detecting a change in the window/door status until the value is sent.
Periodic Send (0 = Disabled) [0…24][h]: allows configuring a periodic sending in hours of the window/door status.

¹The default values of each parameter will be highlighted in blue in this document, as follows: [default/rest of options].

Alarm: Tamper [enabled/disabled]: enables the object “Alarm: Tamper (Status)” through which a ‘1’ is sent when the device enclosure is removed.

Note: the tamper alarm will be sent 5 times after each change of state or reset.

Alarm: Battery [enabled/disabled]: enables the object “Alarm: Battery (Status)” through which a ‘1’ is sent when the battery level is about to run out.
Whenever this parameter is enabled, Heartbeat will necessarily be enabled.

Important: For correct measurement of the battery status it is necessary to link the Heartbeat object so that it will be sent periodically. Because of this, whenever the battery alarm is enabled, the Heartbeat will also be forced to be enabled.

Note: the battery alarm will be sent twice after each change of state or reset.

ANNEX I. COMMUNICATION OBJECTS

“Functional range” shows the values that, with the independence of any other values permitted by the bus according to the object size, may be of any use or have a particular meaning because of the specifications or restrictions from both the KNX standard or the application program itself.

Number| Size| I/O| Flags| Data type (DPT)| Functional Range| Name| Function
---|---|---|---|---|---|---|---
1| 1 Bit| | C T – – –| DPTTrigger| 0/1| [Heartbeat] Object to Send ‘1’| Sending of ‘1’ Periodically
2| 1 Bit| | C T – – –| DPT Window Door| 0/1| Window/Door (Status)| 0 = Closed; 1 = Open
1 Bit| | C T – – –| DPT Window_Door| 0/1| Window/Door (Status)| 0 = Open; 1 = Closed;
3| 1 Bit| | C T – – –| DPT_Alarm| 0/1| Alarm: Tamper (Status)| 0 = No Alarm; 1 = Alarm
4| 1 Bit| | C T – – –| DPT_Alarm| 0/1| Alarm: Battery (Status)| 0 = No Alarm; 1 = Alarm
