* BOCA RELOCKING: A special type of automatic timed relocking is required. After the release
delay expires, the lock releases. When the door is opened, the iMXD detects this but nothing
happens immediately (the lock remains released). When the door re-closes, a "relock delay" of
30 seconds begins. If the door is not opened again during this 30 second period, it will relock.
If it is opened again, the 30 second relock delay will begin again on door closure. The door will
only relock when it has been left undisturbed for 30 seconds after re-closure. The local authority
may extend the relock delay to 45 seconds for sensitive facilities. The standard iMXD control
board supports the BOCA 30 second relock sequence. If the 45 second relock sequence is
required, contact the factory to receive a modified board.
2.3. DIP SWITCH SETTING
Once you have determined the settings for nuisance delay, release delay, relocking (including
special BOCA relocking), dip switches on the iMXD control board may be set to select these
parameters. The factory set condition
of the board is nuisance delay 1 second,
15 second release delay and standard
(non BOCA) relocking via the internal
keyswitch. If you require a variation
from this configuration, some Dip
Switch settings will have to be altered.
Switch 1: This sets the amount of time
for release delay. In the factory set
(Off) position, release delay is set for 15
seconds. Turning the switch On sets a
30 second release delay.
Switch 2 and 3: The combined position of the 2 switches selects 4 different values for nuisance
delay.
