does this unit have battery backup

It has a battery inside that will keep the memory intact if the power goes out. It doesn't have an operational battery backup, meaning employees cannot clock in and out when the power is out. We have ours hooked up to an APC UPS battery unit. Honestly, even if Icon offered a battery, it'd probably be just as much (or more) than an APC.

There is a 9 volt battery compartment in this unit. This is a hard wired unit, the battery is just for backup.

I have not used with a battery back up system. This is 120v ac only. No option for 12v DC.

It does *not* have a battery backup. Some settings survive a power outage, but some do not. For example, the setting to *not* go into power saving mode is not preserved; the "standby" mode - you have to reset the "standby" power level whenever the power comes back on - to disable that feature is you set the "standby" power level to 0 (zero) watts. The option to turn off the PIR motion detection feature does keep its setting when the power is restored. I don't know what happens to other settings that I do not change from their default values.

No they don't have battery back up. They are great though and I now have them in every room of the house running baseboard heaters. With the exception of the one running the gas fireplace. Battery back up is usually found in the programmable thermostats so it will save your settings in the event of a power outage.

This radio only runs off AC power (120volt). I can not remember if it has battery back-up for the clock. OBTW this is a very nice sounding radio with the ability to work from a number of sources .

If it is plugged in to AC. Mine is not using battery backup and if the power goes off, the unit goes off.

No. It does not have battery backup. During a power outage, it will need to be manually disconnected to allow opening or closing of the garage door.

Not that I know of. Anything plugged in has a battery back up. I am in an area of frequent power failures. More than one a month and it has not been a problem with the security system. You could call GE, I think it is GE/Jasco for the security system. Sorry I don't have the number with me. They are very helpful.

My control box came with a battery back-up, I have had this unit for 3 yrs and very little trouble with it, it is a inexpensive unit, you get what you pay for.

No battery backup in mine. However if the power goes out, your furnace won't run it's fan anyway. When the power comes back on, the thermostat will resume as left off. We have ours in a vacation home and the power goes off intermittently throughout the winter. The thermostat is always reset and functioning when I check back in. I really enjoy this thermostat for checking in on the house and the external temperatures remotely, and for turning on the heat before we arrive in the winter.

Sorry, I have no idea. The unit I received as a gift never worked at all. I really prefer one that plugs into an outlet and has a battery for backup.

No. It has no batteries to use for a backup. So if the power quits, so does the phone

Gee I bought it awhile ago now and it plugs into an outlet, but I checked the description on Amazon and it doesn't say there's a backup battery. There is a little red light though, so if it were to turn off, you'd know it is not working.

Does not require battery backup. Works only on power that is delivered to the heater.If power goes down to your heating, then battery backup would not do any good anyway.Works very well in this manner.

It is not a stand alone unit. It has no battery. It must always stay plugged into an outlet
