The Leak Alert Wi-Fi smart water detector is powered by a Lithium battery allowing for easy placement anywhere leaks might occur and avoiding the limitations of hub-based wired products on the market. When moisture is detected, the Zircon Leak Alert Wi-Fi will sound a 105 dB alarm, emit a visual warning by flashing a SOS, and will send an email alert via your Wi-Fi connection up to five email addresses to warn you of the water leak and potentially save thousands of dollars in water damages. The Zircon Leak Alert Wi-Fi eliminates the need for all the expensive accessory equipment by operating independently on a hub-less platform. Each unit operates independently of each other and can be individually named, allowing for an infinite number of units to be on guard protecting your space from water damage. Use the location of the device as the name utilized during the set-up process and the emergency email will alert you of the exact location of the problem allowing for even faster intervention. Should a flood occur, the Leak Alert Wi-Fi unit will float and continue to send out both the visual flashing and the auditory alarm. Zircon designed the Leak Alert Wi-Fi to chirp and send an email notification when the battery is running low and needs to be replaced. Each Leak Alert Wi-Fi unit includes an easily installed standard 3V Lithium battery to keep your Leak Alert Wi-Fi running at optimal performance. Perfect for HOA, multi-unit, multi-story property management or to protect your apartment, home or office. Just like your smoke detector, remember to check and replace your Leak Alert Wi-Fi batteries every year.

TOPGREENER TDOS5-W Motion Sensor Light Switch, PIR Sensor Switch, Occupancy Sensor Light Switch, Motion Sensor Wall Switch, 500W 1/8HP, Neutral Wire Required, Single Pole, White

Sensor switch detects motion to automatically turn lights on and off based on the occupancy and vacancy in a room.

Motion sensor switch uses a passive infrared (PIR) sensor to reduce false triggers from unwanted movements.

Occupancy switch mode (Auto ON, Auto OFF) and vacancy switch mode (Manual ON, Auto OFF) allow you to customize the sensor according to your needs.

Light switch sensor features adjustable settings. Variable time delay from 15 sec (Test) to 30 min. Adjustable range.

NEUTRAL WIRE REQUIRED, 1,200 square feet coverage, 180 Degree View; 120VAC, 500W Incandescent, Halogen, Fluorescent, LED, CFL, Works with all bulb types. Single Pole Only. Wall plate included.

TOPGREENER TDOS5 combines occupancy and vacancy sensor into one light switch for energy efficiency, security and convenience, while in compliance with the 2011 NEC Code. When no motion is detected within delay time you set, the connected load will turn off automatically. This light sensor switch detects fine motion. Energy Efficiency: The motion sensor light switch automatically turns ON/OFF based on room occupancy, avoiding the waste of energy from leaving the lights/motors on when nobody is in the room, including bathroom, closet, hallway, and office. Running the TDOS5 consumes little power, est. cost only $1 a year. The sensor light switch automatically turns the light on to avoid blind-searching and tripping when entering a dark room. Enhances safety and security: Occupancy sensor switch can also effectively deter thieves and allow security cameras to capture clear footage. To conserve energy and prevent lights from automatically turning on during day time, all you need to do is adjust the light level knob to change the light sensitivity of the sensor. Operating modes: • Occupancy Mode: Light switch sensor will automatically turn on the lights when you enter a room and automatically turn off after the room is vacant, making it especially convenient when entering a room with your hands full. Perfect for many applications such as the kitchen, laundry room, garage, restroom, office, closet, etc. • Vacancy Mode: Requires manually turning the light on and automatically turns the light off when the room is vacant. Vacancy mode is used in rooms that do not need the lights to automatically turn on, such as bedrooms and media rooms. Vacancy mode provides the most energy savings as it ensures that the lights will automatically turn off when the room is no longer occupied. NEUTRAL WIRE REQUIRED
