As per my knowledge, There are mainly two types of mounting options majorly happen for Access control & TA:
1. Wall mount
2. Flush mount or Surface mount
Flush mount option requires architect to be consider final product in well advance and in such products it might not be the standard practice like Elevator and switch boards in building/infrastructure development ??
is there any standard for size (of Gang Box) for flush mounting of such access control product ?
Is Flush mouting feasible in established building (where Flush mouting provision is not covered) ?
However in most cases, Flush mounting type products have more aesthetic appeal compare to wall mounting product.
Please share your experience and views.
