I already have 3 hardwired detectors with no interconnect. I can just replace with these and they will connect right? Prefer hardwired to battery.

The SA521CN replaces one hard wired unit to provide the wireless connection for add-on wireless units such as the SA500. Example: My alarm system had three hard wired units. Replaced one with the 521. I then added four more units to the system wirelessly with SA500 units. Now have seven interconnected detectors in all without running any additional wires.

sorry, I have no idea. I would think that the batteries would be the same. Maybe the contacts of the leads might be different. If so, a soldering iron and some wire would do the trick.

wires are bare ends. you can put what ever you need on the end. the idea of this is to connect it to a 12 volt car battery. it should be wired thru a fuse or fuse block of some sort to protect everything. i bought a blue sea systems st blade fuse block to connect the 2 i have and in turn it is connected to a deep cycle 12 volt battery. wires are 70" long.

Yes - you can use a bolt/washer-battery terminal/ring terminal-washer/nut assembly to connect your wires to the battery. Spray with a corrosion resistant spray before assembling and after if the battery assembly will be exposed to moisture or moist outdoor conditions. Good Luck!

Hello Jason, I know I cut off both connections and hard wired them together. i have a different use than you. Mine is for a snowmanfrom home depot. Radio Shack has power adapters. their adapter did not work for me. These work fine for me. good luck.

unsure .... I did it ..... but didn't check the paperwork. There may be a model variation for hardwiring. Ask manufacture on their site..

Yes, but to do so you must replace one of your existing units with/or add one Kidde 1279-9999/RF-SM-AC Hardwire Smoke Alarm with Battery Backup, Interconnectable, to your existing system (assuming that your presently installed devices are a different brand other than Kidde). The Kidde 1279-9999/RF-SM-AC is capable of communicating with the Kidde 0919-9999/RF-SM-DC Battery-Operated devices and will receive/activate alarms from/to other wired units. If you already have a Kidde 1279-9999/RF-SM-AC installed, then you are in great shape, just add the Kidde 0919-9999/RF-SM-DC units as needed.

My system had connectors for Firex. I purchased the adapter so I did not have to turn off the power to hard wire the detector. If you do not have an installed connector to plug in an adapter, you will have to shut off power to your detectors and use the wire nuts supplied with the replacement detector.

Tim,I bought 2 of these& both were complete NIGHTMARES!!!!! I took them to my computer guy. , his crew took 2 days to get 1 to work & the 2nd unit would not program....so I sent them back .So I really can't help you here...I then did more research & to find out that hard wire is the way to go!!!!Since I have bought 8 hard wired cameras from Swann on AMAZON ,AWESOME CUSTOMER SERVICE !!!!hardwired is the best

I hooked mine up to a transformer and did not use a battery. If you have voltage at the power connections and it does not work I would think you have a bad sensor.

You could have them both connected to the same battery. Each has its own controller. I do not know if you can wire them for any configuration other than 12v....

Kidde sells photoelectric alarms with the sealed 10-yr battery that are very good, they just aren't interconnected. They also have a combination I/P alarm that does both and is interconnected. That one hard-wires though and has a battery backup. If your home is hard-wired then that's the way to go.

You can, but I not sure why. These are hardwired detectors designed to sound an alarm tone on all compatible detectors on that circuit. Seems you might be as well off with a battery operated detector.

Sorry, not sure. The cord is special, and must be bought as a second item for normal wired detectors. Not sure how the wireless would work.

If you don't have one from the two you're replacing, Make your own with some wire & bolts. Connect in series to make 24V.

There is a 3 prong plastic connector that is included in the box. In my situation I didn't have to use it as I was replacing an existing detector using the same connector.

Hi Shard, my initial assumption is that you do not have the connectors in the right place. The batteries are connected in series i.e. mine are 6volt batteries and I have 6 of them for a total of 36v. So the positive connectorhas to be on the 1st batteries positive terminal and the negative connector has to be on the negative terminal of the last battery. If you have it hooked up that way, one of the batteries might be bad. Bill
