WHAT IS NEW IN THE I287BS WIRELESS VISITOR CHIME?
The I236S wireless visitor chime consists of 2 main components. The first is a PIR sensor that detects human movement and body heat within a range of approximately 4–6m. The second is the wireless chime receiver, which operates on RF433MHz and allows users to select 1 of 38 available sound modes. The system can be used as a visitor notification device for stores, offices, hotels, showrooms, and similar locations, helping staff recognize when a customer arrives. For the 2025 version, the chime has been upgraded with the ability to assign and lock a specific ringtone and volume level for each connected device. It also includes additional Vietnamese greetings and reminder messages such as “Hello,” “Thank you,” and “Goodbye,” as well as reminder messages for places of worship, offices, and other quiet areas, such as “Please leave your shoes outside” and “Please do not talk loudly.” In addition, 4 alarm siren tones and emergency alert sounds are available for applications such as elderly assistance calls, balcony alerts for children, or anti-theft warning.
What makes the 2025 Kawasan i287B visitor chime different from other products on the market?
- A specific visitor chime, alarm, or emergency sound can be assigned to each push button, PIR sensor, or magnetic door sensor, helping users identify which area has been activated.
- Additional push buttons can be integrated for use as wireless doorbells, emergency call buttons, alarm buttons, or assistance call devices.
- Can be used as an automatic reminder device for visitors entering places of worship, hospitals, offices, and other designated areas.
- Can function as a wireless alarm system. The PIR sensor does not require a 220V power supply and operates using AAA batteries. The chime receiver can be installed in the location where the alarm needs to be heard.
- Can be integrated with an RF signal repeater to extend transmission range when required, with an operating range of approximately 100–300m depending on installation conditions.

SETTING A FIXED RINGTONE AND VOLUME FOR EACH PUSH BUTTON OR SENSOR
Step 1: Select the desired sound and volume level. Step 2: Press and hold the SET button for approximately 4–5 seconds. When the red indicator below the logo starts flashing, release the button and press the push button 1–2 times. If pairing a PIR sensor, move the sensor switch from OFF to ON after installing the batteries. Step 3: Wait approximately 3–4 seconds, then press the push button again or walk in front of the PIR sensor to test the system. If the chime sounds, pairing is successful. Note: Once a specific sound and volume have been assigned to a push button or sensor, the ringtone cannot be changed simply by pressing the ringtone selection button on the chime receiver. To change the assigned sound, the previous setting must be deleted and the device must be paired again from the beginning by following Steps 1, 2, and 3 above.APPLICATIONS AND BENEFITS OF THE KAWASAN I287BS WIRELESS VISITOR CHIME
- Suitable for visitor notification in stores, hotels, guesthouses, showrooms, clinics, offices, and similar locations.
- Because different sounds or greeting messages can be assigned to different sensors, one PIR sensor can be installed at the entrance with a greeting such as “Welcome, we are pleased to serve you,” while another sensor at the exit can play “Goodbye” or “Thank you.”
- Can be used as an automatic reminder device when someone enters a place of worship or quiet area, for example: “Please keep silent” or “Please leave your shoes outside.”
- Can be used as an assistance call device for elderly or sick people. An emergency sound can be assigned to a push button placed beside the bed so that help can be requested quickly when needed.
- Can function as a wireless alarm system. Users can select 1 of 4 alarm siren sounds, install the PIR sensor in the monitored area, and place the chime receiver inside the house or room.
- Suitable for entrances monitored by cameras. When the chime is activated, the user can immediately check the surveillance camera to identify which entrance has activity and respond accordingly.
- The I287B supports up to 4 PIR sensors connected to 1 chime receiver, and 1 PIR sensor can also be paired with multiple chime receivers. This helps users monitor multiple entrances while reducing equipment costs.
- Sound output of up to 100dB allows the chime to be heard clearly in various environments.
