3.5 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.
4. 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 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. When changing Dip Switch settings, note that
the board must be repowered as the switch settings are read on power up.
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.
MATRIX #1: Switch 2 Off; Switch 3 Off (factory set): nuisance delay disabled
MATRIX #2: Switch 2 On; Switch 3 Off: 1 second nuisance delay
MATRIX #3: Switch 2 Off; Switch 3 On: 2 second nuisance delay
MATRIX #4: Switch 2 On; Switch 3 On: 3 second nuisance delay
Switch 4: This implements BOCA timed relocking. In the factory set (Off) position, standard
relocking from a momentary reset switch is implemented.
When the switch is turned On, 30 second delayed BOCA relocking is set. Under some conditions,
local authorities may require a 45 second delayed BOCA relocking. The standard XDT board
does not support this. Contact the factory to order a modified board with the 45 second feature.
See section 3.4 for a description of BOCA relocking.
5. POWER
Two versions of the XDT exist which operate respectively on 12 or 24 VDC. Voltage can vary
from -10% to +20% and must be filtered or regulated. Pulsating DC (transformer +
bridge rectifier) is not acceptable. If you are forced to use pulsating DC, install a 1000
Microfarad capacitor across the board's "+" and "-" terminals to create a filter. The reason why
the XDT is not a dual voltage board is that it includes 3 relays and therefore draws a relatively
large amount of current. Supplying separate versions for the 2 voltages minimizes the current
draw but the board will still draw a maximum of 100 mA at 12 VDC or 50 mA at 24 VDC.
As this is high for a timer, be sure that your power supply is of adequate capacity to support the
load of the board with that of the electric lock.
A related power issue is a description of how the board behaves upon loss of power or reduction
of the input voltage. It is always intended that the XDT is permanently powered except
in the event that the fire alarm system removes all power from the delayed exit
locking system.
In the "normal" condition, the lock control relay (C3) and the remote alarm relay (C2) are
energized. The local alarm relay (C1) is deenergized. In this condition, the lock is powered
(secure) and no alarms are being signaled. If the board loses power from a broken wire for
instance, the lock control relay will deenergize releasing the electric lock. This is a safety
feature. The remote alarm relay will also deenergize which will signal trouble at the door. This
