A Appendix
Scenario Example
For a skylight lock with a
bolt, the 1 (+ –) to 14 (+ –)
ports of the skylight
controller do not supply
power to the bolt under
normal conditions. After
you press the skylight open
button or start remote open,
the 1 (+ –) to 14 (+ –) ports
supply power to the bolt.
Then the bolt draws in and
the skylight opens.
Take a skylight magnetic
lock for example. Normally,
the 1 (+ –) to 14 (+ –) ports
of the skylight controller
supply power to the lock.
After you press the skylight
open button or start remote
open, the 1 (+ –) to 14 (+ –)
ports do not supply power to
the magnetic lock. Then the
magnetic force of the
magnetic lock disappears
and the skylight opens.
