Have a 12V door strike in place from the lock smith. Customer wants a push button release in her office and a keypad at the door. Also wants a timer to have the door remain open at certain times.
I have spec'd in a regular door bell, a Camden keypad and a Camden timer.
How would you wire this?

Curious as to what the manufacturer says.

first you have to find out if the lock is fail safe or fail secure . If it is fail secure, applying power for extended period of time ( to keep it open ) will damage the lock.
When fail safe lock is used, disconnecting power to lock will keep it open .

With a fail secure lock, you could resort to a motion detector (on both sides) that would unlock the door when appropriate.

An access control panel, like this from CDVI :
would make this a very easy setup for under a $1K. Create schedules, power the strike/motions/PTE's, etc.

If it needs to remain unlocked for extended periods, the locksmith needs to supply a fail-secure strike rated for continuous duty.
There are lots of simple stand-alone keypad solutions, but adding the timer requirement I'm in agreement with others that a small access controller is the best solution.

A good answer is easier with a clear question giving the make and model of everything.
