INPUTS
Each controller can monitor the state of up to 16 inputs such as magnetic contacts, motion detectors, temperature
sensors or other devices. The following are examples of the type of inputs that can be monitored:
Magnetic Door Contact:
Permits supervision of door “status” (opened, closed, opened too long, forced open).
Inputs 1 and 9 are assigned by default as the door contact of doors 1 and 2 respectively.
When using defaults, you can easily swap terminals when troubleshooting.
Request for Exit (REX):
The device used can be a push button, vertical-view motion detector or floor mat sensor.
The door can then be programmed to unlock on a REX detection. Not required if there is a reader/keypad on both
sides of the door. When a magnetic door contact is installed, the system can differentiate between a door forced
open and an authorized exit. Inputs 2 and 10 (3 and 11 for NC Input Connection above) are, by default, assigned
to REX of doors 1 and 2 respectively.
Inputs can be installed to a maximum distance of 1000m (3300ft.) from the controller when using AWG #22. Only
one of the following input connections can be used per controller (see Figure 13).
NC INPUT CONNECTION (8 INPUTS)
When using this method, only one device can be connected to each input for a total of eight input devices. All
i
nputs on the selected controller must be connected using the NC Input Connection Method described in
Figure 13. This setup will not support tamper and wire fault (short circuit) recognition, but will generate an
alarm condition when the state of the input is breached. Only odd numbered inputs (1, 3, 5...) need to be
programmed.
ATZ 2R CONNECTION (16 INPUTS)
This method allows you to connect two devices to each controller input for a total of 16 input devices. All
i
nputs on the selected controller must be connected using the ATZ 2R Input Connection Method described in
Figure 13. This setup will not support wire fault (short circuit) recognition, but will generate an alarm condition
when the state of the input or its tamper switch is breached. Since an EOL resistor is not installed in this
configuration, if the line is cut, a tamper alarm will be generated.
ATZ 3R CONNECTION (16 INPUTS)
This method allows you to connect two devices to each controller input for a total of 16 input devices. All
inputs on the selected controller must be connected using the ATZ 3R Input Connection Method described in
Figure 13. This setup will generate an alarm condition when the state of the input or its tamper switch is
breached. An alarm condition will also be generated when a wire fault (short circuit) occurs.

RELAYS
Each controller has two 30VDC, 110VAC, 5A resistive form “C” relays with a “normally open” and a “normally
closed” contact. These relays can be used to activate alarm sounders or other devices such as lighting control, air
conditioning. An additional 14 relays can be added per controller by connecting two CA-A460 Relay Expansion
modules to the controller’s E-Bus. The relays can be programmed to activate or deactivate according to a schedule,
input or event.
