Smart Home Accessories

Smart home accessories are add-on devices for a smart home or security system, led here by Ajax. The range includes Ajax WaterStop wireless shut-off valves that close the water supply when a leak is detected, LifeQuality air quality monitors, keypads, relays and replacement housings, alongside CIE Group KNX modules, an EZVIZ portable solar panel, a Ring rechargeable battery and a Videofied keypad.

Choosing Smart Home Accessories

Choose the valve by the pipe it will sit on, then plan how it will be powered and what will tell it to close.

Sizes and threads

The WaterStop DN15 Smart fits a 1/2" line and the WaterStop 3/4" is the DN20 version with a BSPP threaded valve. The WaterStop Jeweller DN25 and the WaterStop Smart Motorised Shut-off Valve are the two 1" (DN25) valves, and the Jeweller DN25 has BSP parallel female-to-female threads.

What closes the valve

Most WaterStop valves here can close through automation scenarios as well as on a leak alarm. The DN15 Smart and DN25 Jeweller take Ajax LeaksProtect or third-party leak detectors as triggers and can be closed from the Ajax app. The DN25 Jeweller integrates with the Hub 2, Hub Plus, Hub Hybrid and ReX. Closing takes about 5 seconds on the 3/4" valve, about 5 to 7 seconds on the DN15 Smart and up to 7 seconds on the two DN25 valves.

Power and battery life

Each valve runs on 4 x CR123A batteries. An external supply of 7.5 to 14 V can be added to every valve, and on the 3/4" valve it turns the batteries into a backup. On the DN20 and both DN25 valves the batteries last up to about 3 years, depending on settings or use.

Local control and protection

Each valve can also be worked on site, with a lever, a button or both. The 3/4" valve adds stuck-prevention rotations and thermal and overload protection, and the 1" smart valve has an anti-tamper mounting lock and a sabotage alarm.

Frequently asked questions

What are smart home accessories?

Smart home accessories are add-on devices that extend a smart home or alarm system, such as keypads, relays, air quality monitors and water shut-off valves. They usually link to a hub by radio or a wired bus and are set up in an app. Check that an accessory suits your hub and its protocol before fitting it. The range here includes Ajax keypads, LifeQuality monitors and WaterStop valves.

What is an electronics housing?

An electronics housing is the outer case that encloses a device's circuit board and protects it from dust, knocks and tampering. On alarm and smart home devices, a replacement housing can let you renew a cracked or worn case without replacing the electronics inside. Check that the housing matches the exact device it is meant for. The range here includes replacement housings for Ajax devices.
