Keri Systems, Inc. Technical Reference Manual – PXL-250 and SB-293 7.0 PXL-250/SB-293 System Installation 7.1 Advance Planning A successful, easy to maintain installation requires advance planning - making sure the site has everything necessary for a successful installation and making sure that all materials are placed in easily maintainable locations that take advantage of the features the PXL-250 access control network has to offer. 7.
Technical Reference Manual – PXL-250 and SB-293 7.3.2 Keri Systems, Inc. Distributed Mounting Distributed Mounting places a controller near each door. The RS-485 network communication cable is then routed to every controller on the access control network. The benefit of distributed mounting is that less cable is needed for the reader and the necessary inputs and outputs as they are all near the controller. Only the network cable needs to be routed throughout the installation.
Keri Systems, Inc. 7.5 Technical Reference Manual – PXL-250 and SB-293 The Enrollment Reader The enrollment reader is the "A" reader on the master controller on the access control network. The Doors access control software expects all card enrollment by presentation information to come from the "A" reader on the master controller. For ease of card enrollment, the enrollment reader and master controller should be physically near the host computer running the Doors software.
Technical Reference Manual – PXL-250 and SB-293 7.7 Keri Systems, Inc. RS-485 Networking The PXL-250 uses a half-duplex, RS-485 communication bus. This is a very robust system and has been tested to exceed standard RS-485 industry specifications. Using approved cable and good installation practices, the network will operate satisfactorialy with up to 16,000 feet of cable for systems of up to 128 PXL-250 controllers, each with an SB-293.
Keri Systems, Inc. Technical Reference Manual – PXL-250 and SB-293 All Keri Systems proximity readers use 5 to 12 VDC power (except for the MS-9000 which uses 12 to 24 VDC power) while most Wiegand compatible readers use just 5 VDC power. For Wiegand configured PXL-250W controllers, there is a reader power warning LED on the controller board to indicate if the controller is applying 12 VDC to the Wiegand compatible reader (see Figure 7-1 on page 29).
Technical Reference Manual – PXL-250 and SB-293 7.9 Keri Systems, Inc. SB-293 Jumper Settings On the SB-293 satellite board, there is only one jumper that may require setting. JP12 configures the satellite board for either second door control or for general purpose inputs and outputs (see Figure 7-2, and Figure 10-1 on page 71). • • Placing a Jumper across JP12 pins 1 and 2 configures the satellite board for general-purpose inputs and outputs.
Keri Systems, Inc. Technical Reference Manual – PXL-250 and SB-293 Figure 7-3: Satellite Board/Controller Installation 7.11 Wiring Connections to the Boards There are several things to keep in mind when making the wiring connections to the PXL-250 and SB-293 boards. When routing cables into and inside an enclosure: DO • Route cables in accessible areas whenever possible for ease of maintenance.
Technical Reference Manual – PXL-250 and SB-293 8.0 Keri Systems, Inc. Understanding Inputs and Outputs The following section provides descriptions of all Inputs and Outputs on the PXL-250 Controller and the SB-293 Satellite board. Wiring diagrams for all inputs and outputs are included in the next section, Wiring Connections beginning on page 39. 8.1 Inputs An input detects a state change generated by a device outside of the controller.
Keri Systems, Inc. Technical Reference Manual – PXL-250 and SB-293 NOTE: If a Door Status switch is not being used, a jumper must be installed across pins 1 and 2 of TB-4 (for the PXL-250 Controller) and pins 1 and 2 of TB-8 (for the SB-293 Satellite board). This prevents a continuous Door Open signal from being received by the controller and it ensures proper operation and annunciation of Door Forced and Door Held Open alarms.
Technical Reference Manual – PXL-250 and SB-293 Keri Systems, Inc. While there is no one there to activate a Global Unlock request, the input remains open. When someone desires to globally unlock all doors, this person activates the Global Unlock device (typically a normally open switch), closing the circuit and generating a state change. The master controller then responds to this state change per programmed instructions and generates an output unlocking all doors and allowing exit.
Keri Systems, Inc. 8.2 Technical Reference Manual – PXL-250 and SB-293 Output Relays In many respects, a Form C output relay performs the opposite task of an input. An input detects a state change generated by a device outside of the PXL-250 or SB-293. An output relay, however, receives a signal from the controller that energizes the output relay, switching its state. This state change typically prompts an action outside of the controller.
Technical Reference Manual – PXL-250 and SB-293 8.2.1.2 Keri Systems, Inc. Fail-Secure 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.
Keri Systems, Inc. 8.2.4 Technical Reference Manual – PXL-250 and SB-293 General Purpose Output Relay A general-purpose output relay receives a signal from the controller that energizes the output relay, switching its state. This state change typically initiates or ends an action outside of the controller. 8.2.4.
