Lock Drive
There are two voltage free relays (A & B) on the P2 Controller for operating locking
devices.
Readers
The controller has 2 proximity reader channels for use with P2 readers only. Reader A
is designated out and Reader B is designated in.
Inputs
The P2 Controller has four inputs terminal blocks for external devices:
a door sensor input (DR),
a Request to Exit input (RQE),
an Intruder input for connecting to an alarm panel and,
a Fire input for connecting to a fire panel.
Resetting to Factory Defaults
The controller can be reset to factory defaults by pressing and holding the reset button
located at the bottom right of the board for 7 seconds.
Supply
The P2 Controllers require a 12V DC PSU (not supplied). The actual operating range
is between 10V DC and 14V DC.
Network
Figure 1 shows both USB and Ethernet connectivity options to the P2 controller from a
host PC. The upper part of Figure 1 shows the 3801 P2 Controller using the 3803 P2
USB Interface
The lower part of Figure 1 shows connectivity to the 3802 P2.net Controller using a
LAN or WAN.
Additional 3801 P2 Controllers can be added to the system by linking them together in
a daisy chain using the P2 Network. Doors Express will support a maximum of 16
controllers per system.
The End of Line Resistor jumper is set to N as default. This should be changed to Y if
the P2 Controller is the first or last controller on the daisy chain network.
Cable
Network
Two core twisted pair cable is to be used to wire the P2 Network (a screened cable can
be used to offer better protection).
If the optional screened cable is used then the incoming and outgoing screen can be
fitted to SCR on the Network terminal block. It is important to remember that the
screen needs to be earthed to ground at one end of the network.
