Maglock on existing exit door to building

[katwalatapan]

I had a query with regards to the application of a delayed egress system on existing exit door. The existing exit door to the building is not fire-rated. It has a normal mechanical latch to it. To be compliant to code, do I have to remove the existing mechanical latching device and only use maglock on the exit door or could systems co-exist.

Thank you.

If the power goes out - how do you get out. I believe they can/must co-exist

What's wrong with a crash-bar system like you see at Timmy's?
