6. The Cypress SPX-1300 provides additional data channels to support access control hardware such as door
strikes, tamper alarms, request to exit status, etc. These signals are sent to and from the Remote and Central units
without the need to run additional wiring.

The accessory control I/O use active low inputs. When the inputs are floating (nothing connected) the associated
output will be set to a high level. When the input is set to 0Volts (Ground) the input will activate its associated
output. All Accessory outputs are Open Collector type and will switch to Ground when activated.
"
"
Each input will have an associated output. See the following pages for a diagram of each I/O pair.
"
Inputs can be tested by making a jumper connection to ground and monitoring the associated output.
