2.2 Back Panel

Figure below shows the connections and switches on the rear of the SAFR SCAN reader.
  • Reset Button: Located just to the right of the opening. Hold button for 10 seconds while device is powered to reset device to factory defaults.
  • Aux Port: Future use
  • PoE: Networks and power over ethernet
  • T1: Terminal Block 1 containing Wiegand and Relay connections.
  • T2: Terminal Block 2 containing OSDP, TTL and Power connections.
  • OSDP Termination Switch: Located under Pin 1 and 2 of T1 terminal block. Set to On (up) on furthest reader if multiple readers on bus. Default is Off (down)

2.2.1 Terminal Blocks

The T1 and T2 terminal blocks are shown without the terminal blocks to reveal the OSDP Termination Switch which is located under the T1 terminal block. The terminal blocks allow wires to remain connected while SAFR SCAN is removed from the wall. This can be useful when staging your devices on a bench for installation.

Be careful not to switch the terminal blocks when replacing. This will not harm the SAFR SCAN device but can result in confusion as the device will not function properly.

To remove the terminal blocks, pry gently upwards with your fingers or needle nose plyers. The terminal blocks require a 2mm flathead screwdriver to loosen or tighten the screws that hold in the wires.

2.2.2 OSDP Termination Switch

When installing SAFR SCAN to a panel with OSDP, the termination switch should be set to enabled (down position) for the last reader on the bus. By default, the switch is enabled (down position) and suitable for single reader connected to the panel. When installing multiple readers in daisy chain configuration, the termination switch should be disabled (up) for all readers except the reader furthest from the panel.

2.2.3 Reset Button

Reset button is located just inside the upper left mounting opening. It is a round button just to the right of the mounting hole. Press this button for 10 seconds while device is connected to power to reset to factory defaults. Reset is complete when LED next to Aux Port change from flashing orange to solid red.

This will remove all data (identities, credentials, account and networking settings) and restore device to original factory defaults. The firmware version is maintained.

2.2.4 Back Panel Inputs and Outputs

Figure below shows the T1 and T2 terminal blocks on the rear of the SAFR SCAN reader. The T1 terminal block includes Wiegand in and Wiegand out terminals as well as a Normal Open and Normally Closed relay. The T2 terminal block (Right) includes OSDP in and OSDP out terminals as well as TTL connections and auxiliary power.

The diagram depicts either a Wiegand configuration (left) or an OSDP configuration (right) with SAFR SCAN taking input from an external card reader and providing output to the PAC Panel. Note that some SAFR SCAN models include a built-in RF card reader.

  • OSDP/Wiegand/TTL: 22 AWG shielded twisted pair wire, 4000 feet (1200 m) maximum.
  • Relay: NC/NO 120 VAC / 24 VDC max, 1 Amp max. 22 AWG wire.
  • Aux Power:12 VDC @1 Amp / 24 VDC @ 0.5 Amp (12W). Polarity reversible. 22 AWG wire.
  • PoE: PoE 802.3af, Class 3; 14 watts.

Tools Needed

  • 2mm flathead screwdriver (for terminal block screws).
  • 2mm hex wrench (for SAFR SCAN device two Mounting Plate screws).

2.2.4.1 Aux Port (USB)

The auxiliary USB port is used to connect SAFR SCAN to a breakout box that can be located remotely from the device thru a secure cable. This allows unsecured connections such as Wiegand or TTL to be placed on the secure side of the door.

The breakout box will be available June 2023 and includes all connections on the rear of the SAFR SCAN panel as well as USB Ports for additional device storage. The breakout box is connected with a USB-A cable.

2.2.4.2 Ethernet

SAFR SCAN ethernet port provides two primary functions.

  • Remote management of the reader thru IP local area network
  • Device power (optional) thru PoE (see Power below for more details).

2.2.4.3 Terminal Block Pins

Terminal block pins are used to interface into external hardware. The terminal block can be removed from SAFR SCAN to easily attach external wiring. Each terminal block has 8 pins. A 2 mm flathead screwdriver can be used to secure wires to the terminal block.

Table below describes the function of the different inputs and outputs.

Wiegand In

SAFR SCAN can connect to Wiegand sources such as an external reader to allow multi-factor authentication. These ports are also used for the SAFR Time and Attendance Feature.

⚠️ You must enable Wiegand In in Software Settings to activate these ports.

Wiegand Out

SAFR SCAN can connect to the access control panel using Wiegand protocol.

⚠️ You must enable Wiegand Out in Software Settings to activate these ports.

OSDP In

SAFR SCAN can connect to OSDP sources such as an external reader to allow multi-factor authentication.

⚠️ You must enable OSDP In in Software Settings to activate these ports.

OSDP Out

SAFR SCAN can connect to the access control panel using OSDP protocol.

⚠️ You must enable OSDP Out in Software Settings to activate these ports.

Relay

Two relays are provided. One Normal Open relay that closes the circuit upon authentication and one Normally Closed relay that opens the circuit upon authentication. Both NO and NC relay share a common ground connection.

NO/NC relay do not provide power. Power must be provided by external source.

TTL

These pins will offer ability to receive or send signals in future firmware updates.

2.2.4.4 Power

SAFR SCAN is powered in one of two ways

  • PoE cable - PoE 802.3af, Class 3; 14 watts (Device draws 12 watts max).
  • Auxiliary Power - Power via 12 volts DC source to pin 7 and 8 on terminal block T2. Polarity is reversible - ground can go on either pin.

Power can be delivered either via PoE ethernet or DC power to pins 7 and 8 on terminal block T2. If powered ethernet is not available, use Aux Power on pins 7 and 8 to power. Ethernet is still recommended for remote management.

2.2.4.4.1 Power redundancy

SAFR scan supports redundant power supply. If power is delivered for both PoE and Aux power, SAFR SCAN will draw 50% of its power from each source. If power to either of the sources fails, SAFR SCAN will increase power draw to the remaining source with no interruption in service.

2.3 Installation

For information on installation of SAFR SCAN standard (SC100, SC200-RF) or mullion (SC50) readers see the respective guide for each product.
