Input and Output Requirements

General Purpose Inputs

These are free inputs that can be used for various functions.

The following should be defined:

Single door controller: Door 1 – IN 2

Door 1 – IN 2A

Double door controller: (no general purpose

inputs available)

General purpose inputs are suitable for most uses. For example,

they might be used to detect tampering, to activate alarm

sensors or for monitoring power supply failure.

General purpose inputs are activated when the panel is

opened.

Note:

When fitting the AC-225U, the internal tamper switch must

be connected to a UL Listed burglary unit.

Refer to the UL Listed burglary unit for connection

instructions.

4.3 Outputs

Rosslare Security recommends the use of suppression diodes

for all outputs that will be connected to inductive loads and

activated by DC current, such as Magnetic Lock ("Maglock")

or door strike devices.

Each suppression diode should be connected near its

inductive load. Be careful to attach the diode's cathode to be

tied to the +V terminal of the load. Attach the diode's anode

to the –V terminal.

Door Lock

There are two types of door locking devices:

• Fail open (fail secure)

• Fail close (fail safe)
