System Output Overview
The unit has two door lock relays and two auxiliary output relays that can be activated in response to reader activity, time schedules, or input
conditions.
All relays are Form-C SPDT and provide non-powered dry contacts rated for 5 Amps. Power for the relay loads can come from an external power
supply or from an optionally installed Power Distribution Module board.
Output Defaults
All outputs are assigned default features that can be congured as needed. The following table shows the default states for each of the two output
types:
OUTPUT DEFAULT STATE DEFAULT RESPONSE
DOOR LOCK OUTPUTS
NOT ENERGIZED,
SINGLE PULSE
3 SECOND UNLOCK TIME IN RESPONSE TO CORRESPONDING READER ACTIVITY
READER #1 INPUT ACTIVATES DOOR RELAY “A”
READER #2 INPUT ACTIVATES DOOR RELAY “B”
AUXILIARY OUTPUTS
NOT ENERGIZED,
SINGLE PULSE
NO DEFAULT RESPONSE
MUST BE CONFIGURED VIA PROGRAMMING.
Recommended Wiring Requirements
The power cable must be the proper gauge for the current load and should not be routed in parallel with other wiring especially high voltage or AC
wiring. Refer to the table for wiring recommendations:

Wiring - Best Practices
1. Terminals are in a separate bag. This allows the installer to pull through the cabinet ~12’ of cable and wire to the terminal not mounted to the
board.
2. Make sure the cable drops down in the housing prior to connecting to the PCB. This will allow for condensation to drip to the bottom of the
cabinet and not directly to the PCB boards.
3. Cabling for system ground always needs to be the correct cable type and gauge as dened for the system..
4. Be sure to use the transient protection where recommended.
5. The Entry series includes a power supply. It is not intended to power locking hardware or other devices.
Relay Wiring for Door or Pedestrian Gate Control
1. Door Lock Relays A & B can be used to control electromechanical access devices on doors. The door will unlock when a user is granted access
by the system. The door will remain locked if a user is denied access (see diagram, next page).
2. The door lock relay outputs can each be congured to operate in fail-secure or fail-safe modes.
3. In fail-secure mode, a door lock relay energizes when access is granted.
4. In fail-safe mode, a door lock relay de-energizes when access is granted.
