PHYSEN Wireless Doorbell Kit: 58 Ringtones, 5 Volume Levels, 1300-ft Range, LED Strobe, Waterproof.

👍 Long Wireless Range - Our wireless remote button leverages high-frequency electronic technology to control the doorbell chime. With an impressive range over 1300ft (400m) in open space, this doorbell ensures clear control even from a distance. It features strong anti-interference capabilities, allowing one-to-one pairing to prevent signal cross-connections with neighboring units, ensuring seamless operation.

👍 Waterproof & Easy to Install - Crafted from high-quality ABS material, our doorbell and chime system boasts robust IP55 waterproof functionality, operating from -4°F to 140°F (-20°C to 60°C). Easy installation is a breeze with the plug-and-play design of the doorbell receiver, and the transmitter can be adhered to walls using double-sided tape or secured with screws.

👍 Multiple Optional Ringtone & Mute Mode - The PHYSEN classroom doorbell receiver offers 58 distinct chimes and a 5-level adjustable volume setting (0 dB to 110 dB) to suit various needs. A bright LED flash is ideal for the elderly and hearing-impaired, enhancing visibility. The chime indoors retains your last melody and volume level after being closed, eliminating the need to reset previous settings, which saves valuable time.

👍 Expandable and Multi Use - Our wireless doorbell system is designed for flexibility. Add more receivers or doorbell ringer buttons as needed, choosing from 1 button with 1 receiver, 2 buttons with 2 receivers, or even 2 buttons with 3 receiver sets. Configure multiple doorbell chimes to ring with different ringtones for your front and back doors, ensuring no visitor is missed.

👍 Wireless Doorbell Kit and Warranty - The comprehensive kit includes 3 wireless transmitters, 3 plug-in smart doorbell receivers, double-sided mounting tape, anchors, screws, and an A23 battery. Our commitment to quality is reflected in the 18-month warranty and 24-hour customer service. If you have any questions, feel free to reach out to us.
