Output Connectors
Four six-pin terminal strips provide connections for door strike and/or magnetic lock control.
The four terminal strips are labelled on the circuit cards as T2, T3, T4 and T5. The output ter-
minals are Form-C type dry contacts from relays located on the 4-reader board. For each out-
put relay, Normally Closed (N/C), Normally Open (N/O) and a common terminal (COM) are
provided.
Each relay also has an LED associated with it that lights whenever the relay is activated.
T2 provides output connection points for readers 1 and 2. T3 provides output connection
points for readers 3 and 4. T4 provides connection points for two spare relays. T5 provides
two spare relay output, except on the first 4-reader board. T5, I/O 8 provides a common alarm
output for all Reader board.
On 4-reader board 1, the last relay is assigned in the software to provide a common alarm out-
put from the controller. This relay is intended to provide an easy hand-off by the controller of
an alarm indication to an external burglar alarm system. The common alarm relay will activate
whenever a Door Forced Open or Door Held Open alarm is detected by the controller. It will
also activate when the controller's door tamper circuit is activated, or in occurrence of an AC
power failure.
The common alarm relay will reset when all alarm conditions have returned to normal.
Detailed information concerning the common alarm output is provided elsewhere in this man-
ual.
