3.0 CONSOLE WIRING EXAMPLES
3.4
Installation Procedure
Step 1
– Select appropriate wiring diagram
.Fig. 6, 7, or 8 to wire the console direct to door locking devices or via relay modules.
Step 2
– Wire External Relay modules.
If used configure and wire external relay modules, such as SDC
’s UR-1 or UR4-8 (see applicable installation manual)
Step 3
– Terminate the Lock Power / Control Wiring (Switch Outputs 1-4).
Determine whether the switch outputs will be used to switch lock power directly or as dry signal outputs to auxiliary relay boards.
Follow the wiring diagram appropriately for fail-safe or fail-secure locks. Be careful to observe lock voltage polarity. NOTE: All low
voltage lock wiring shall be 18-gauge minimum (wire gauge shall be determined by the SDC wire gauge chart or another voltage drop
too). Signal wire shall be 22-gauge minimum.
Step 4
– Terminate the Door Monitoring (Optional LED Inputs)
Connect the Door Position Status switches, Latch Status switches to the LED inputs directly or via secondary relays, per the
appropriate wiring diagram.
Step 5
– Terminate Key Switch / Reset Outputs (Optional)
A1, A2, A3 Output
– This SPDT output is controlled by either the Key Switch or the momentary Reset button which connect to the I/O
board at input J8. Refer to section 2.1.2 on Page 9 for more information.
Step 6
– Connect 24VDC Power Source to the Power inputs.
Before applying power, verify that all the connections are securely terminated by gently pulling on each wire. Connect 24VDC power
to the I/O board Power Input, as shown in the wiring diagram. Be careful to observe polarity.
Step 7
– Verify Operation
Test operation of door locking devices and LED
’s by pressing each rocker switch. If applicable, verify operation of LED’s and alarm
buzzer, by opening each door without pushing a button, causing a forced door alarm. Verify operation of Audible Shunt button by
pressing it to silence the forced door alarm. Test operation of Key Switch and Reset Button if connected.
