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 Dahlia Seeds — Huge Difference in Quality
    Size: 1-Pack, Style: Zinnia Dahlia, Size: 1-Pack, Style: Zinnia Dahlia
    Excellent germination rate and very fast growth! I planted these seeds side-by-side with another Dahlia seed packet from a different seller on the exact same day under identical conditions, and the difference has been amazing. By day 23, these seedlings were already thriving — healthy, vibrant, and growing quickly with a very high germination rate. The plants look strong and vigorous, and I’m extremely impressed with the quality of the seeds. If you’re looking for Dahlia seeds that actually perform well and establish quickly, I would absolutely recommend these. I’m excited to see them continue growing and blooming

    Size: 1-Pack, Style: Zinnia Dahlia
    This package had more than the pkg that was supposed to have 4000, but they are coming up slowly. It is dry here, I have been watering , just enough to get the ground wet and they are scattered, but some are coming up. I also watered the space supposedly where i spread seeds from the supposedly 4000 seeds pkg. They are not coming up as much!

    Didn’t get a review on the garlic powder
    Size: 1-Pack, Style: Zinnia Dahlia
    The seeds were okay but the garlic powder that I ordered was smaller than usual is a case of bait and switch
