  • Reset Button: Hold button for 10 seconds while device is powered to reset device to factory defaults.
  • Wiring Harness Connector: Wiring harness included with SC50 reader and provides wiring for OSDP, Wiegand, Relay, TTL, Auxillary Power and Ethernet.
  • OSDP Termination Switch: Set to On (right) on furthest reader if multiple readers on bus. Default is Off (left).

3.2.1 OSDP Termination Switch

The OSDP Termination switch allows SAFR SCAN to be installed on a daisy chain bus without the need for adding external RS485 EOL termination resistor. Setting the switch to the on (right) position will insert the resistor in the circuit. This is required for the last SAFR SCAN on the bus or for a single SAFR SCAN installed on a long wire run. Setting the switch to off (left) will remove the RS485 EOL termination resistor from the circuit. The factory default setting is off.

3.3 Connecting POE and Wiring

To open a door, you need to connect SAFR SCAN to a PACS panel or use the Relay to release a door latch. This requires both physically connecting the SAFR SCAN device to a PAC panel as well as configuring the SAFR SCAN software to take advantage of the new connection.

Note that SAFR SCAN supports both Wiegand and OSDP connection types. SAFR SCAN also includes a dry contact relay to operate door hardware directly.

3.3.1 SAFR SCAN SC50 Configurations

SAFR SCAN SC50 can operate as a standalone or networked device depending on the installation hardware used. When installed in standalone mode, device is powered over 2-wire DC and managed over Bluetooth. When installed in networked mode, device is powered over either POE (Power over Ethernet) or 2-write DC and can be managed over Ethernet and/or Bluetooth.

3.3.2 Standalone Configuration

The SC50 comes with a wiring harness as shown below which is all that is needed for standalone installation.

The USB-C shown is used for Ethernet and power over USB and not utilized in standalone configuration. See Wiring Diagram below for color coding.

3.3.3 Networked Configuration

In Networks configuration the USB-C connector is used to carry both Ethernet and power. If the switch does not provide power, then power can be separately wired through the + and – DC wires. The figures below shows the POE Network Connector Box assembly (Part # SFR-SC10-L). There are two different assemblies that ship with SAFR SCAN. Refer to the diagram that matches the assembly you received.

  • OSDP Termination Switch: Set to On (right) on furthest reader if multiple readers on bus. Default is Off (left) .
  • Relay: NC/NO 120 VAC / 24 VDC max, 1 Amp max. twisted pair, 18 AWG.
  • OSDP/Wiegand/TTL: 22 AWG shielded twisted pair, 4000 feet (1200 m) maximum.
  • Aux Power: 10 VDC @1 Amp / 30 VDC @ 0.3 Amp (10W). Polarity reversible. 22 AWG wire.

Tools Needed

  • #1 Phillips screwdriver (SAFR SCAN device to Mounting Plate screws).

3.4.1 Wiring

For all connections, do the following:

  1. Strip wire ends about 1/8” and connect to panel wiring.
  2. Verify the wires are securely fastened.

⚠️ ALWAYS include ground wire with connectivity to panel ground. (Unlike card or PIN-only readers, scan is not powered from panel and thus requires a shared ground with panel or Wiegand/OSDP signals may not be interpreted correctly).

⚠️ Device must be grounded through earth ground to avoid issues arising from static electricity.

Text Description automatically generated⚠️ Device must be shielded from strong continuous sunlight to avoid damage to display.

Wire SAFR SCAN to PAC Panel as follows (see diagram above for wire color coding):

Wiegand Connections

OSDP Connections
  1. Connect Wiegand Out Ext1 on SAFR SCAN to the corresponding input on the PAC Panel.
  2. Connect Wiegand Out Ext0 on SAFR SCAN to the corresponding input on the PAC Panel.
  3. Connect Ground on SAFR SCAN to the corresponding input on the PAC Panel
  1. Connect OSDP Out D0/B/- on SAFR SCAN to the corresponding input on the PAC Panel.
  2. Connect OSDP Out D1/A/+ on SAFR SCAN to the corresponding input on the PAC Panel.
  3. Set OSDP Termination switch per below.
  4. Connect Ground on SAFR SCAN to the corresponding input on the PAC Panel
  • Terminal labels on PAC Panel may vary, but are generally described as one of D1 and D0, A and B or + and -

  1. Remove mounting bracket from SAFR SCAN SC50 housing by unscrewing the two screws at bottom of housing using a 2mm hex wrench.
  2. Attach mounting bracket to mullion or wall using 2 pre-drilled countersunk screw holes. Ensure threaded tabs (B) at bottom.
  3. Hook SAFR SCAN housing to the hooked tab (A) and slide scan housing up until contacting threaded tabs (B).
  4. Secure SAFR SCAN to mounting bracket with two screws using #1 Phillips screwdriver.

Tools Needed

  • #1 Phillips screwdriver (SAFR SCAN device to Mounting Plate screws).

Notes:

  • SAFR SCAN SC50 is not rated for outdoor usage.

3.5.1 Attach Mounting Bracket to Door or Wall

SAFR SCAN can be mounted to the mullion or wall using the included bracket. The bracket is removed from the back of SAFR SCAN SC50 by removing the 2 Phillips head screws. Then the bracket may be mounted to a wall using 2 flat head course metal screws or machine screws and bolts (not included). SAFR SCAN SC50 is then attached back to the mounting bracket using the 2 included Phillips head screws. The process is described below.

1. Remove bracket from SC50

The hooked flange (A) of the bracket is the top. See diagram above. The bottom of the bracket has 2 threaded tabs where the Phillips head screws attach the bracket to the reader.

Place the bracket against the mullion and mark holes in the 2 countersunk holes in the bracket. Also mark a spot to drill a 1 inch (2.5cm) hole where the wiring connector and harness will be run into the door mullion. The hole should be centered horizontally and 1 inch below the top of the rectangular opening in the bracket as shown above.

3.5.2 Attach Bracket to Mullion

The bracket should be attached to the mullion with two 1/8” self-tapping course threaded metal screws. A pilot hold should be drilled to a suitable size for the selected self-tapping metal screw. These are not included with the mullion reader and will need to be purchased separately.

Drill 2 pilot holes in the mullion at the 2 locations marked using the SC50 bracket 1/8” screw holes. Also drill a 1” opening in the mullion for the wiring harness using the mark created as described above.

With all holes drilled, use the 2 1/8” self-tapping metal screws to attach the mullion bracket to the door mullion.

3.5.3 Connect Cables

Connect the necessary cables based on the following options

  • If needed, run Wiegand, OSDP, or Door Relay wires out through the 1” hole drilled for the wiring harness and connect to the corresponding wires on the SC50 wiring harness as described in the wiring diagram. Make sure to connect ground as well.
  • If not using SC50 ethernet adapter (i.e. reader will be managed via Bluetooth), run 2 power wires and ground to a power source capable of 9 watts (see wiring diagram for power requirements).
  • If using SC50 eithernet adapter, run ethernet out through the 1” hole drilled for the wiring harness and attach USB adapter as described above.

Mount SC50 to Bracket

With the bracket attached to the door mullion, place the SC50 into the over the bracket with the hooked flange aligned to the rectangular opening on the SC50 as shown below.

Then set the bottom of the mullion onto the two threaded tabs on the bottom of the mullion bracket.

Finally, Use the two Phillips screws the attach the SC50 to the bracket through the two countersunk screw holes at the bottom of the reader as shown below.

3.5.4 Enable SAFR SCAN Inputs and Outputs in Software

For security reasons, SAFR SCAN has Wiegand, OSDP, or Relay disabled by default. To enable these, open SAFR SCAN Web Console and do the following from the System configuration page.

  1. Enable Wiegand, OSDP, or Relay outputs as needed (see wiring diagram on flip side).
    • Wiegand: System > Wiegand > Wiegand connection to Control Panel = Enabled.
    • OSDP: System > OSDP > OSDP connection to Control Panel = Enabled.
    • Relay: System > Door Strike Relay > Electric door strike relay = Enabled (adjust duration if needed).
  2. Add credentials to person record.
    1. Go to People > Edit Person and set the following:
      • Access Clearance = Unlimited (to use access clearance settings on your access control panel).
      • Access Card Format = Select applicable format.
      • Access Card Facility ID and Access Card ID = Set to facility ID and user ID, respectively.

Now SAFR SCAN should be sending signal to panel to unlock door or close relay when a face matching a person record with suitable Access Clearance is presented.
