LOCK WIRING
Wiring the door locks will vary on the type of lock (e.g., Door Strike or Maglock) and "environment"
you wish to employ: fail-safe or fail-secure.
Fail-safe (e.g., Maglock):
If the lock loses power (e.g., from a power failure), the door will unlock.
Fail-secure (e.g., Door Strike):
If the lock loses power (e.g., from a power failure), the door will
remain locked.
Determine which type of environment to use. Is the access control point an area where people need
to exit in case of emergencies? Does the access control area require its doors to lock after a power
failure (e.g., to prevent vandalism)?
