Note: Appling voltages above 30V to REL1/REL2 terminals will damage electronic components used
to protect relays’ contacts, this will corrupt functionality of relay output.
In normal state NC terminal is shorted to COM while NO remains isolated. When active, NO is
shorted to COM while NC is isolated. When controller is not supplied or supplied with voltage below
its minimum level, relay outputs remain not active.
IO1 and IO2 transistor outputs
There are two programmable, transistor outputs IO1 and IO2 available on CPR32-SE controller, both
have identical electrical structure. Each output can sink max. 1A DC to GND; switched voltage must
be 15V DC or less. The IO1 and IO2 are internally protected from currents above 1A and can be
configured as Normal or Inverted. When configured as Normal they normally remain in high
resistance state while when set to Inverted they normally are shorted to ground.
CLK and DTA lines
These lines can be used either as inputs or outputs and can be programmed to several input/output
functions. Once the function for the line is selected system will reconfigure it to work as input or
output. Electrically, both lines have identical electrical structure. When operated as outputs they can
sink max. 150mA DC however applied voltage must not exceed 15V DC.
Input and output functions
Name Type
Description
[00]: None
None
No function assigned to line.
[01]: Clear alarm on CPR
Input Triggering this input clears all alarms on CPR
module.
[02]: Tamper loop
Input Triggering this input starts tamper alarm which can
be signalled on outputs: [67], [71], [73], [81]
[03]: RTS communication line
Input Used for connection with communication interface
when Flow Control option in use. Active state on this
input indicates external host (usually PC) requests
communication token.
[08]: Set all doors to Normal mode
Input Triggering this input switches all controllers within
network to Normal door mode.
[09]: Set all doors to Unlocked
mode
Input Triggering this input switches all controllers within
network to Unlocked door mode.
[10]: Set all doors to Cond.
Unlocked mode
Input Triggering this input switches all controllers within
network to Conditional Unlocked door mode.
[11]: Set all doors to Locked mode
Input Triggering this input switches all controllers within
network to Locked door mode.
[12]: Clear alarms in system
Input Triggering this input cancels all valid Door Alarms on
controllers and CPR module itself.
Note: Door Alarm is a composite state which
consists of at least one of following alerts: Door
Forced, Prealarm and Door Ajar.
[13]: Clear alarms on controllers
Input Triggering this input cancels all valid Door Alarms on
controllers in network.
[14]: Reset APB
Input
Triggering this input clears APB Register on CPR and
all APB Registers on controllers in the network as
well.
Note: When APB Register is cleared every user can
login first time either on entry or exit to room/zone
