KALER Wireless Call System for Disabled WC – Set with Smartphone Alarm

The KALER wireless call system is designed for use in toilets to provide a reliable way for people with disabilities to call for help. The set includes the KAL-HC-CWT central unit, a KAL-ST2 pull button, and a KAL-L3 optical-acoustic indicator. When the pull cord is activated, the indicator emits both light and sound signals, and the system sends an alarm to your smartphone via the Tuya Smart app.

• Wireless connection – no cables needed; transmitters communicate with the central unit at 433 MHz, and the central unit connects to the internet via Wi-Fi.
• IP66 waterproof pull button allows disinfection and safe use in wet environments.
• 200m range on open area, extendable with a signal repeater.
• Up to 400 transmitters can be paired with one central unit.
• 85 dBA siren ensures the call is heard even through closed doors.
• 5-hour battery backup keeps the system operational during power outages.
• Multiple notification modes – sound, light, and smartphone push alerts.

This set is ideal for hospitals, care homes, and private residences where quick assistance is needed. Easy to configure via the Tuya app, available for iOS and Android.
