SB-293 Satellite Board

2.0 Cable Requirements

• two conductor, stranded, AWG 22 or a larger gauge for all input/output connections

NOTE: The Lock Output relay may require a heavier gauge of wire depending upon the current demands of the lock and
the length of the lock wiring run.

3.0 When Installing Satellite Boards

DO

• route cables in accessible areas for ease of maintenance

• add transient suppression across electric devices attached to a satellite board output

• use an isolation relay (Keri Systems P/N IRP-1) if attaching to a parking gate, a turnstile, or any application using a
large electric motor

• for a single door application, install the door's reader to the TB-5, "A" reader connection on the controller

• for a two door application, install the primary door's reader to the TB-5, "A" reader connection on the controller
and install the secondary door's reader to the TB-6, "B" reader connection on the controller

DO NOT

• stretch or over-tension cables

Quick Start GuideSB-293

• route cables over sharp objects

• let cables or wires get tangled

4.0 Jumper Setting

JP12 - Configures the Satellite Board (see Figure 1)

• 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 controller board).

5.0 Board Installation

Perform the following steps to install an SB-293 Satellite board on a PXL-250 controller (see Figure 2).

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 Figure 2).

4. Align the Satellite Board to Motherboard connector pins (J2 and J3).

5. Gently press the two boards together with each stand-off into its mounting hole and with the connector pins
meshing together.

6. Turn the controller’s power ON.

If the J2 to P2 connector pins have been meshed together properly the LED on the SB-293 turns green (see Figure 4 on
page 4).

SB-293 Satellite Board

8.0 General Information on Inputs

A controller input detects a state change generated by a device outside the controller that may prompt a response from
the controller. Input devices that generate a state change may be normally-closed or normally-open. This section
provides a brief description of normally-closed versus normally-open inputs.

8.1 Normally-Closed

A normally-closed input device continually keeps a circuit active or complete. A state change is generated when the
normally-closed input device is forced open, breaking the circuit. In an access control system, a door switch is a typical
example of a normally-closed device. While the door remains closed, the switch remains closed. When someone opens
the door, the door switch is opened, breaking the circuit and generating a state change. The controller then responds to
the state change and generates an output (such as sounding an alarm if the door is a secure door).

8.2 Normally-Open

A normally-open input device continually leaves a circuit open, or incomplete. A state change is generated when the
normally-open input device is forced closed, completing the circuit. In an access control system, a request-to-exit (RTE)
button is a typical example of a normally open device. In an access control installation, an RTE button is located on the
secure side of a door. While there is no one there pressing the button, the switch remains open. When someone desires
to exit through a secure door, they press the RTE button, closing the circuit and generating a state change. The controller

Quick Start GuideSB-293

then responds to this state change and generates an output (such as unlocking the door to allow egress).

9.0 General Information on Safety versus Security with Door Locks

When installing a door lock there are two things to consider: safety versus security, or should the door be "fail-safe" or
"fail-secure."

9.1 Fail-Safe Door Lock

Fail-safe means that if the power should fail at a door (perhaps due to a power outage or equipment failure), the door
will automatically unlock allowing entrance or egress. Power is required to keep the door locked. A fail-safe door
ensures people will be able to enter and exit a secured area through that door in the case of an emergency. A typical fail­safe application may use a magnetic lock. In this application, the controller energizes the lock relay, causing the lock
relay to change its state. In its new state the normally-closed circuit is opened breaking the power to the magnetic lock
and allowing the door to be opened.

9.2 Fail-Secure Door Lock

Fail-secure means that if the power should fail at a door (perhaps due to a power outage or equipment failure), the door
will automatically lock and not allow entrance, but will continue to allow egress. Power is required to unlock the door.
A fail-secure door ensures a secured area remains secure regardless of the situation. A typical fail-secure application
may use a door strike. In this application, the controller energizes the lock relay, causing the lock relay to change its
state. In its new state the normally-open circuit is closed activating the release mechanism for the door strike on the
door to be opened.
