Function
The inactive leaf can be
un­locked simultaneously when
the active leaf is opened. The
door co-ordinator guarantees
that the inactive leaf will close
before the active leaf.
The inactive leaf engages the
latch on the HZ Automatic Flush
Bolt, which causes the bolt to
shoot and lock the inactive leaf.
