number and this option is set to Yes, then outputs 17 and 18 are used for the
lock.
Two zones are also needed for this operation to work. One for the normal door
open contact (for example, reed switch) and one for the monitoring of the door
lock status that comes from the electronic lock. The two zones needed are taken
from options "5.1.n.6.1.1 Door zone" on page 199 and "5.1.n.6.1.2 Second zone"
on page 207.
The function is programmed in "5.1.n.6.2.3 Pulsed L&UnL" on page 208.
The specific operation is as follows.
Door Open procedure
On presenting a valid user at this reader, the second relay will pulse on for 0.5 s.
After 0.2 s of the second relay switching on, the first relay will pulse on for 0.5 s.
If according to the zone monitoring (explained below) the door has not opened, it
will continue this procedure for the "5.1.n.5.1 Unlock time" described on page
198. If a "Door Unlock" command is sent, this procedure is permanently
continued. The procedure continues every 1.5 seconds. See timing diagram in
Figure 23 below.
Figure 23
The difference between Door Open and Door Unlock is: The Door Open
command only unlocks the door for the Unlock Time, whereas the Door Unlock
command opens the door permanently until a Door Lock command is sent. See
also "1.2.13 Door control" on page 139.
Door Lock procedure
The second relay will pulse on for 0.5 s. If according to the zone monitoring
(explained below) the door has not closed, this procedure will continue until it
does. See timing diagram in Figure 24 on page 73.
