SB-293 Quick Reference
2.0 Input Connections
2.4 General Purpose Input Device
This Quick Reference is designed for the experienced installer as a quick reference while installing to ensure
all connections are made and working properly.
The Quick Reference is designed as a checklist of sorts where you may check off as each installation
procedure is completed. Additional information is given for those who need to be reminded of what is
performed during that part of the installation. For detailed information on installing the SB-293 Satellite
Board, see the SB-293 Satellite Board Quick Start Guide
Reference Manual (P/N 01836-004).

3.1 Lock Relay – Fail-Safe
In the event of a power failure at a door set up with a fail-safe lock relay, the door will automatically unlock
allowing people to exit through that door.

1.0 Before Turning Power ON
Install the SB-293 Satellite board on a PXL-250 controller.
1.Turn the controller's power OFF.
2.Line up the upper left-hand corner of the Satellite PCB with the controller PCB.
3.Line up the stand-offs in the top two corners of the Satellite PCB with corresponding mounting holes
in the controller PCB (see the Satellite/Controller Installation drawing below).
4.Align the motherboard connector pins (J2 and J3) to the Satellite Board connectors (P2 and P3).
5.Gently press the two boards together with each stand-off into its mounting hole and with the
connector pins meshing together. Once power has been applied, the LED on the SB-293 (see Figure
1) will turn green if the J2 to P2 connector pins have been meshed together properly.
If the controller is not using a door contact switch, verify a door switch input jumper is connected
between TB-8, pins 1 and 2.
Verify JP-12, the 2-Door/Input-Output configuration jumper is set correctly: OFF for 2-Door control –
ON for general purpose I/O
• Jumper across JP12, pins 1 and 2, configures the Satellite board for general purpose inputs and
outputs.
• NO jumper across JP12 configures the Satellite board for second door control with additional inputs
and outputs. When the Satellite board is configured for second door control, the primary door must
be connected to the "A" reader (TB-5 on the PXL-250 controller board) and the secondary door
must be connected to the "B" reader (TB-6 on the PXL-250 controller board).

3.2 Lock Relay – Fail-Secure
In the event of a power failure at a door set up with a fail-secure lock relay, the door will automatically lock
and not allow entrance, but will continue to allow people to exit through that door.
