what is the purpose of installing the remote head and is there any requirements as to where you can mount it?
 
i am referring to the remote heads that come off the exit signs and are typically mounted right above the door on the outside of the building. sorry it's my first post.

The purpose is to get the light where you need it, and you need to mount them in places that will give you at least 1 footcandle in your exit paths. The other purpose is to save on the cost of a battery unit, if a nearby battery unit will handle the cheaper remote head run off of it. The placement and such isn't something the electrician normally decides. Even when there isn't really much on the E sheets, the emergency lights and exit signs will normally be drawn on right where the designer/engineer/architect wants them.
 
I've seen them mostly used near the exits. Battery & circuit boards are inside with a couple heads, and the remotes are outside the door.

In the words of Homer Simpson, "do'h!" I had a senior moment in my initial reply. It just did not register with me what remote head he was questioning. I kept coming up with sprinkler heads for some reason, and could not get that out of my system.

good catch !
 
I've been told it's for the use of the fire department and I was wondering if that's true.

Say a given installation requires ten units for emergency lighting. You could purchase (for $100 each) and install 10 complete units with batteries and transfer circuitry in each unit. Or you could purchase 5 complete units ($100 each) with remote head ($10 each) capabilities.

Now you've spent $1000 on the ten complete units and only $550 on the complete/remote combination units. Also you have 5 less battery packs to replace in the future.

The prices are hypothetical but I think that you'll get the idea.
 
Hi there!! In case you are also installing building mounted lighting, sometimes you can include an emergency light withing the outdoor light (i.e a wallpack including an emergency light):smile:
