Aico RadioLINK Switched Input Module. 10 Yr Lithium Battery only
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
- 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 Ei408 and the smoke, heat and CO alarms used in the system.
- Features built-in tamper proof FDK Lithium cells, capable of lasting at least 10 years under normal usage. Operating the yellow ‘on/off’ switch sited on the back of the unit activates the cells. The LED on the front cover will flash red, amber, green on power up, after this it will flash green every 40 seconds to indicate a healthy power supply.
- Low battery warning signal – LED indicator flashes amber every 10 seconds to indicate depleted battery. If this occurs the complete unit should be replaced.
- The unit has built-in wiring terminals for connection to an external set of volt-free switched contacts. On the contacts closing, the Ei408 will send out a RadioLINK alarm signal to trigger all other RadioLINK devices within the system.
- 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 from 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 must 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.
- 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. The Ei408 is conformant to EN300220-1 (2000-09) (RF Performance) and EN301489-3 (2002-08) (EMC).

4 Paws up! My dogs LOVE them
Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large, Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
I have 2 large dogs who LOVE THESE.
A Great Pyrenees mix who’s a skinny 80lbs and a lab/terrier mix who’s a chunky 50lbs. They both love bones and can REALLY chew through them quickly so I’m really picky about what I buy them.
Here is what is important to me and how I rate and choose bones. These are my comments on this bone set specifically:
Do they break/splinter?
-They don’t splinter, I have seen smaller pieces that have broken off and when the bone gets down to the end (but this is normal with bones) at which point those pieces can be thrown away. I have never had an issue with them choking, being too small or hurting my dogs though and they are aggressive chewers so I could see this happening with some dogs and never happening with others. 4/5 stars for this.
Do they smell/leave stains on the carpet?
-Nope! No odor and they actually leave my dogs breath smelling better and their teeth cleaner! 5/5 stars
Does it upset my dog’s stomach? (My bigger guy can’t tolerate a LOT of things, he vomits often and also gets diarrhea if he eats the “wrong” thing so I have to be very cautious.)
-NOT at all! No upset tummies. This is always very, very important to me. Make sure you have lots of water nearby for your pups though, these will make them very thirsty. 5/5 stars
Do they hurt my dogs tongue, mouth or teeth?
-Nope, no issues with this. They’re able to gnaw into these aggressively without hurting themselves. 5/5 stars
Are they gone in 2 seconds?
-No! I’m always worried the “stuffed” bones will be left in the dust after the stuffing is all gone but my dogs will still keep chewing on these after the stuffing is gone. They still enjoy the bones and they last for quite some time, weeks at minimum. I can also stick some peanut butter or other treats back in the middle after they get the original stuffing all out of them to “reuse” them if it seems like they’re getting a little bored with them. 5/5 stars
Do my dogs ACTUALLY LIKE THEM?
-They love them. 5/5 stars
Price?
-Great and totally affordable. $20 for 3 of them.. so less than $7/bone. This is comparable to a bone from the pet store and these last a lot longer than something you would find there in the “fresh” grocery-store-like-section of the pet stores.
I’m an avid review reader, especially when it comes to items for my fur babies because I want the best for them. I truly love these bones and will keep buying them.
I will continue to buy these!

⭐️⭐️⭐️⭐️ Finally Found a Long-Lasting Bone That Actually Keeps My Dog Busy
Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
I’ve tried a lot of filled bones and chew treats over the years, and most fall into two categories: gone in 5 minutes, or upset stomach later. These filled beef shank bones hit the sweet spot.
The bone itself is thick, dense, and real, not a thin, brittle shell. My medium-large dog is an aggressive chewer, and this keeps him occupied for a solid 30–45 minutes working on the filling, then even longer gnawing on the bone afterward.
The filling smells fresh and appetizing (not rancid or overly greasy), and my dog goes crazy for it. We’ve tried the cheese-style and peanut butter–style fillings, and both were a big hit. No crumbly mess, no weird residue, and no digestive issues so far.
What I really appreciate is that these feel safer than many cheaper alternatives. The edges don’t splinter, and the bone wears down gradually instead of cracking.
Why I’ll keep buying these:
• Long-lasting even for power chewers
• Real beef shank bone, not pressed junk
• Filling dogs actually care about
• Helps with boredom and anxiety
• Good value compared to pet store brands
Minor cons:
• Can get a little smelly after heavy chewing
• I supervise and take it away when it gets small (as with any bone)
If you’re tired of wasting money on chews that disappear in minutes, these are a fantastic upgrade. My dog is obsessed, and I finally feel good about what I’m giving him.

Best bones out there
Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
These are the best bones I’ve ever bought. I have a lab puppy and as you can imagine most bones don’t last long around here, but this one keeps him entertained for days.

Sturdy
Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large, Flavor Name: Variety Packs, Size: 3 Pack, Set name: Large
Ok so I'm very happy that my standard poodle seemed to really enjoy this product. She was lacking and biting it for hours and days. That said she has still yet to make a dent in the bone. It seems to be too hard and too thick for her. I was surprised how heavy it was! It is large enough it is completely safe to leave her in the other room with. No strange odor or transfer of color. I'd say for the cost it isn't worth it as she is only getting filling and not able to eat the bone for some reason. Then again she is entertained for hours..so maybe so. Doesn't seem to bother her sensitive tummies either.
