The customer can change from failsafe to fail-secure
configurations as required.
Failsafe or fail-secure
locks are ANSI Grade 1 Heavy Duty with monitoring capability.
The passive infrared DS16O has a selectable relay trigger that is adjustable to 64 seconds, selectable fail-safe or fail-secure
modes for power interruption, and a wraparound coverage pattern for precise pattern control.
Fail-safe and fail-secure
are two terms that are associated with all electromechanical locks.
Strikes are available with integral monitoring switches and can be fail-safe (unlocking on power failure) or fail-secure
(remaining locked during power failure).
