4.2 STANDARD BUILDING CODE
NUISANCE DELAY: Not allowed.
RELEASE DELAY: 15 seconds or extension to 30 seconds with local approval.
RELOCKING: Must occur only when the door opens. A doorswitch rather than a keyswitch must
be used.
POWER: The door must release when DC power to it is cut off. This means that battery backup
of the system power supply may be acceptable, but this is a point to confirm with local authority.
4.3. UNIFORM BUILDING CODE
NUISANCE DELAY: Required and must be set at 2 seconds.
RELEASE DELAY: 15 seconds only.
RELOCKING: Must be "manual" and must be located at the door. This is generally interpreted to
mean that a doorswitch can not be used for relocking. A keyswitch is the typical technique used.
POWER: The door must release when power to it is cut off. The door must also release if power
to the smoke detection system or exit illumination system is lost. This is generally accomplished
by using the same line voltage source to operate the lock power supply as operates the smoke
detection and exit illumination systems. Battery backup for the locks is normally excluded.
4.4 BOCA
NUISANCE DELAY: Required and must be set at 1 second.
RELEASE DELAY: 15 seconds or extension to 30 seconds with local approval.
RELOCKING: A doorswitch must be used and a special type of timed relocking is required. After
the release delay expires, the lock releases. When the door is opened, the doorswitch changes
state but nothing happens immediately (the lock remains released). When the door recloses, 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
reclosure. The local authority may extend the relock delay to 45 seconds for sensitive facilities.
The standard XDT board supports the BOCA 30 second relock sequence. If the 45 second relock
sequence is required, contact the factory to receive a modified board.
POWER: The door must release when power to it or to the building is cut off. Battery backup of
the lock power supply is therefore specifically excluded.
4.5 NATIONAL BUILDING CODE OF CANADA
NUISANCE DELAY: Not allowed.
RELEASE DELAY: 15 seconds only.
RELOCKING: Must be "manual". This is generally interpreted to mean that a doorswitch can not
be used for relocking. A keyswitch is the typical technique used.
POWER: The door must release when power to it or to the building is cut off. Battery backup of
the lock power supply is therefore specifically excluded.
5. DIP SWITCH SETTING
Once you have determined the values to be set for nuisance delay, release delay and whether
you want BOCA relocking used, dip switches on the XDT timer board may be set to select these
parameters. The factory set condition of the board is nuisance delay disabled, 15 second release
delay and standard (non BOCA) relocking. If you require a variation from this configuration,
some Dip Switch settings will have to be altered.
