INTRODUCTION
Brief description
The sensor consists of:
- Detector (Big box).
- Magnet (Little box).
- For the proper operation of the door- window sensor, an energy saver is needed, as it turns off the relay or relays configured when the sensor communicates that the window is opened.

- The product is designed to hang on doors or windows, so that the detector lies on the doorframe and the magnet on the door or Windows. When the door or window is opened, the magnet will be released from the detector, and it will send a message to the energy saver to turn off the relay or relays configured (For example, the air conditioner).
- The detector works with a (CR2450) type watch battery, which has an autonomy of approximately 4 years.
- As long as the battery level is correct, there will be no blinking; otherwise, if the battery is low, it will blink one time every 32 seconds. In that case, the battery must be replaced as soon as possible. In addition, the saver/disconnector is informed of the IVEW system. In the IVEW system, the status of the door (open-closed) and the level of the batteries.

INSTALLATION
IMPORTANT! Please keep in mind that the Door / Windows sensor is designed for indoor use.
Dimensions
The size and location of the anchor points of each part are shown in the image below:

Installation step
- First of all, it should be decided in which door or window it must be installed; it is highly recommended to install it on doors and windows with no looseness. The detector and the magnet should be as close as possible, because the maximum distance between both parts is 1,2cm. If that distance exceeds in any direction, it is probable that it no longer works.
- The DOOR/WINDOW sensor installation must be done following these steps in order:
IMPORTANT!- STICK OR SCREW THE DETECTOR (BIG BOX) ON THE DOOR OR THE WINDOW FRAME.

- Synchronize the sensor and the iswitch ( energy saver)
- To enter the energy saver in synchronization mode, consult the manual of the corresponding energy saver. Once the energy saver is in synchronization mode, press the inner button once using a screwdriver. The red pilot will go on.

- Then the sensor and the energy saver will try to synchronize. The synchronization will be successful when the sensor blinks 25 times quickly for approximately 5 seconds. Finally, the red pilot must go off.
- Repeat it with all the sensors of the same room that must be synchronized with the same energy saver.
- It is highly important not to enter two energy savers at once in synchronization mode because the sensors can be synchronized with other rooms.
- To enter the energy saver in synchronization mode, consult the manual of the corresponding energy saver. Once the energy saver is in synchronization mode, press the inner button once using a screwdriver. The red pilot will go on.
- Do stick or screw the magnet’s base at the indicated point and introduce the cap on the base.

- Once the sensor is synchronized correctly, we will install the sensor in the window or door in the right way.
- To check that the sensor correctly detects the magnet, hold the sensor button pressed until the red light is turned off and the sensor makes a series of 10 quick flashes. Indicating that the sensor has been introduced into the Magnet Test mode.
- After those blinking, we will have 20 seconds to install the detector on the base, in a way that the arrow pictures that have both caps match. (The cap’s arrows must match)

- To ensure that the sensor is working properly after installing it, we must look for the red LED to be on during those 20 seconds.
- Once those 20 seconds run out. The LED will blink 10 times for 2 seconds, indicating the output of the test mode and leaving the sensor ready to work.
- If you want to re-enter the magnet test, you must perform the same steps as explained in point 5.
- Finally, for a better grip between the lid and the base of the sensor, it is recommended to insert a DIN7981 2.2mmx6.5mm screw through the hole located in the upper side of the box.

- STICK OR SCREW THE DETECTOR (BIG BOX) ON THE DOOR OR THE WINDOW FRAME.
IMPORTANT!
- In case the battery is not introduced into the battery holder. We should introduce it, and soon afterwards, the LED blinks 10 times for 2 seconds.
- Once those blinking are made, the sensor will be in TEST mod. As a consequence, we should wait 20 seconds before the LED blinks 10 tifor 2for2 seconds, showing that it is no longer in TEST mode.
- To perform the desynchronization or erasure of the sensors in the energy saver, consult the manual of the corresponding saver.
- The desynchronization will be necessary in the following cases:
- When one of the room sensors must be deleted.
- When a sensor is damaged, it is replaced with a new one.
- After the desynchronization, it is always necessary to synchronize the room sensor with the new energy saver.
- The desynchronizing will NOT be necessary in the following cases:
- When the sensor battery is replaced.
- When a new sensor is added to a room.
SENSOR CONFIGURATION
The sensor will be configured by default as a door sensor.
- The Door/ Window sensor has four operating ways: one as a Door sensor, a Windows sensor, a Minibar sensor, and the other as a Twin Door.
- Depending on which application it is used for, it must be configured one way or another.

- To configure the sensor in one way or another, we must move the DIP Switch in one way or another:

OPERATION
- The DOOR/ WINDOW sensor has a wireless Communication with the Iswitch energy saver, and in turn may be connected with the IVIEW system.
- The different operating ways are the following:
- The DOOR / WINDOW Sensor detects any opening or locking of the DOOR/WINDOW sensor and sends an alarm status. Until there is no opening detected, the energy saver will not switch off the relay or relays. (For instance, air-conditioned)
Blinks summary
| State of the red LED | Number of blinks | During the Blinks(seg) | |
| Initial Blinks | Short Blinks | 10 | 2 |
| Test output | Short Blinks | 10 | 2 |
| Correct Synchronization | Short Blinks | 25 | 5 |
| Low Battery | Short Blinks | 1 | 0.01 |
SWITCHING OFF THE RELAY OR RELAYS OF THE ENERGY SAVER
- The switching off of the relay or the relays (Depends on configuration) when the window is opened will be configurable from 0 to 250 seconds in multiples of 5 seconds.
- For instance, if the energy saver’s relay 2 is temporized with 30 seconds and the window is opened after 30 seconds, the energy saver’s relay 2 will turn off.
- To configure this switch-off time, consult the manual of the corresponding server.
CLEANING AND MAINTENANCE
- For the longevity of the device, please follow ing instruct belowions:
- Replace the battery from time to time, every two years or when the sensor asks for that by 3 red blinking. lights
Battery replacement
- When batteries are about to run out, the sensors warn the user, in order to be replaced.
- The detector blinks 1 time red every 32 seconds, showing low battery.
- For replacing the battery, the following steps must be followed:
- Remove the rear cover of the detector as shown in the picture:

- Remove the CR2450 battery from the PCB as shown in the picture and replace it with a new one in the same position. Check that the detector flashes red when the new battery is inserted.

CAUTION: Make sure you are introducing a battery with the appropriate polarity. - Once the battery is replaced, put the detector cap on over the base and ensure that it’s been correctly installed.
- Remove the rear cover of the detector as shown in the picture:
TIPS FOR PROTECTING THE ENVIRONMENT
- Batteries may be damaged if they are not disposed of appropriately. Protect the environment by throwing the worn-out batteries in an authorized collection point.
