Chapter 3: Wiring
Chapter 3 provides wiring diagrams and associated
procedures.
3.1 Wiring the
prox.pad plus Unit Select one of these three wiring options, Alarm Shunt,
Forced Door, or Propped Door, depending on how
the prox.pad plus unit’s AUX relay is to be employed
for this installation (refer to Chapter 4 for program-
ming information). Then refer to sections 3.1.1- 3.1.5
as appropriate.
3.1.1 Wiring the Door
Contact Input
In order for the Alarm Shunt, Propped Door, and
Forced Door features to work, a door contact switch
must be used. Before wiring the AUX relay, connect a
door contact to the keypad. See Figure 3-1 for details.
To solve the problem of people “tailgating” in behind
personnel using valid access protocol, the Auto Re-
Lock feature is provided. With Auto Re-Lock, a long
door open time can be programmed. Auto Re-Lock
overrides the lock output timer, resetting the door
open time as soon as the prox.pad plus unit senses
that the door is open. A long door open time allows
people sufficient time to carry packages from the prox-
imity reader/keypad to the door and open it before the
timer runs out.
No programming is required to implement this fea-
ture.
After a valid access or egress, the prox.pad plus unit
senses that the door switch is open and drops the main
relay immediately. This disengages the lock, which
locks behind the person regardless of how long it takes
that person to get through the door.
NOTE: This feature requires that you use the “Door
Contact” input as shown in Figure 3-1.
