Aico Mains RadioLINK Relay Module with 5A Relay. 230V with 10Yr+ Rechargeable Backup

    This module triggers the alarms in a system if an external device is activated, such as a sprinkler system.

    Features

    • 10-year life, sealed in lithium cell
    • Connects with the alarm system using RadioLINK wireless interconnection technology
    • Connects wirelessly with all other Aico wireless interconnection products

    Specifications

    • A relay module with cover to allow flexibility in siting.
    • For use with 140RC when using an Ei168Rc RadioLINK base, 160e when using and Ei100MRF RadioLINK + module, Ei3000 series when using an EI3000MRF SmartLINK module or any RadioLINK enabled CO alarms.
    • Eliminates the need for any cabling between the Ei428 and the smoke, heat and CO alarms used in the system.
    • Requires 230V AC Mains Power Supply – Green LED to indicate mains power is present.
    • Features built-in tamper proof Rechargeable Vanadium Pentoxide lithium standby cells, capable of lasting at least 10 years and powering the module initially for at least 2 months in the event of mains power failure. The cell manufacturer endorses a minimum 10-year life expectation for the rechargeable cells, which are activated by operating the battery switch inside the module.
    • The product is CE marked to indicate conformance to BS EN 60065:1998 (Electrical Safety), EN300220-1 V1.3.1 (2000-09) (RF Performance), EN301489 V1.4.1 (2002 08) (EMC) and has been 3rd party tested for electrical safety in accordance with Annex K of BS 5446: Pt.1:2000.
    • Radio frequency: 868 MHz Band in accordance with R&TTE Directive 1999/5/EC – this band has been designated for use with security products and only allows a 1% duty cycle, so continuous transmission and interference form external sources is extremely remote, and would be illegal.
    • Range: The type of building will be the major limiting factor e.g. the number and type of walls/ceilings that the radio signal has to pass through. As a guide, 30m should be the maximum distance between any of the RadioLINK units in the system.
    • Up to 20 RadioLINK units can be used in one system. Range will be the limiting factor.
    • Low back-up warning signal – LED indicator flashes RED every 10 seconds to indicate that the lithium cells are depleted.
    • Units are in ‘Factory Code’ mode when received (they will all communicate with each other). They must be ‘House Coded’ to eliminate the risk of adjacent properties communicating with each other. After ‘House Coding’ they will only communicate with other RadioLINK units coded at the same time.
    • House Code: Operate the ‘House Code’ switch on all RadioLINK units in the system – see the instructions supplied with other RadioLINK units being used. The green LED on the cover of the Ei428 will change to red and flash slowly, this indicates that it will receive the unique serial numbers being sent by all other RadioLINK units in ‘House Code’. The number of flashes of the LED indicates the number of units in the system, The Ei428 will return to normal standby mode automatically after 15 minutes. Pressing the ‘House Code’ switch again will return it to normal standby immediately.
    • Volt free contacts – (Normally Open or Normally Closed) rated up to 240V AC / 5 Amps, making it suitable for use with a wide range of AC or DC voltages. The relay contacts operate on mains power, or on back-up cells in the event of mains failure.
    • A RadioLINK Manual Call Point, Ei407 and remote control switches Ei450, Ei412 and Ei411H are also available for use in the system. See separate specification sheet(s) for further information.
    • Features 1 x 25mm trunking for for surface wiring and centre knockout for recess wiring.
    • Ambient Temperature Range: 4°C to 40°C.
    • Humidity Range: 0 to 90% relative humidity.
    • 5-year guarantee.
    • Manufactured in Ireland.

    Excellent fit and value - recommended buy
    Size: 3+12+12+2+1 pack
    I rarely write reviews, but I'm so impressed by the fit and quality of this set that I made an exception. I'd been running my eufy 11S without brushes, and have been cleaning and reusing the filters for a while now and finally decided to buy replacements. The kit came packed well with everything in order and no damage. I replaced all of the worn parts and installed the brushes and did a test run - everything worked great. I expected some fitment issues because I've seen that with other kits, but I had no issues. The fact that you get multiples of almost everything is icing on the cake. Oh, and I wasn't paid or given anything in exchange for this review, as much as that's worth now, haha. I can recommend getting this kit for your robot vacuum, if it's the right set for your model.

    Good option for an aftermarket replacement solution.
    Size: 3+12+12+2+1 pack
    I've been very happy with this product. I think it is a good price point for what is included. Everything was a directly compatible and everything fit as you would expect. The filter quality is good and since there are plenty in the kit I find I change the filters more often which is probably a good thing. I recommed.

    Eufy Brushes wear out with daily use
    Size: 4 Pack
    These brushes help the Eufy continue to run efficiently. I have 2 dogs and run 2 Eufies daily. It is surprising how much sand, dust, gravel and hair gets vacuumed. My furniture isn't as dusty and my floor doesn't need mopping as often.

    Fits my old eufy
    Size: 3+12+12+2+1 pack
    This set fits my older model eufy and has extra parts for newer models. The filters did not fit our model (our fault for not doing proper research) but the fan sweeper is awesome.
