4 Hardware Setup

4.1 Mounting SAFR SCAN

SAFR SCAN can be mounted to the wall in one of two ways. Flat mount is for situations where the SAFR SCAN reader is mounted to a wall that is parallel to the plane of the door. Wedge mount is useful when the SAFR SCAN reader is mounted to a wall that is perpendicular to the plane of the door. Each method is described below.

  4. Align SAFR SCAN reader onto Mounting Bracket (see documentation for details)
  5. Hold SAFR SCAN in place while fastening to Mounting Plate threaded tabs (C) with included screws.
  • For outdoor, see Outdoor Installation Requirements below.

4.1.2 Wedge Mount Instructions

For Wedge Mount, the SAFR SCAN Wedge Mount is mounted to a standard 4” junction box. The Junction box is first secured to the wall. With junction box mounted, follow instructions below to mount SAFR SCAN to the junction box.

  1. Mount Wedge Mount to junction box with recessed Junction Box mounting holes (B) (screws not included). Wedge may be mounted with angle left, right, up, or down depending on need.
  2. Follow instructions for Flat Mount to mount the SAFR SCAN reader to the wedge mount using the Wedge Mount threaded holes (A)

Note that only four of the Wedge Mount threaded screws are required to secure the SAFR SCAN Mounting bracket to the Wedge Mount.

The assembled wedge mount should look like the following.

4.1.3 Outdoor Installations

Use of an outdoor waterproof junction box with an IP65 rating or greater is required for outdoor installations. Mounting gaskets included with the SAFR SCAN mounting bracket are supplied and must be used for the bracket to SAFR SCAN housing and bracket to junction box. Proper torque must be applied to junction box screws to ensure a tight seal. Over tightening of the mounting bracket to junction box screws may lead to deformation of the bracket which will compromise the seal.

Outdoor installation requirements:

  • 1/8 bead of silicone around rubber gasket on both sides of the Mounting Plate.
  • The junction box should be conductive and connected to Earth ground.
  • A weatherproof junction box.

  • Reset Button: Located inside and 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).

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. 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.

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 (up) 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 (down) will remove the RS485 EOL termination resistor from the circuit. The factory default setting is off.

Previous generation housing has following differences:

  • Reset button above Terminal Block T1 (functions in same way as newer generation housing).
  • No OSDP Termination Switch (external 1k Ohm resistor required for furthest reader on multiple reader configuration).

4.3 Connecting SAFR SCAN to a PAC Panel

To open a door, you need to connect SAFR SCAN to a PAC 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 low voltage relay to operate door hardware directly.

4.3.1 Wiring Diagram

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 relay with Normal Open and Normally Closed connections. The T2 terminal block (Right) includes OSDP in and OSDP out terminals as well as TTL connections.

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.

  • OSDP/Wiegand: 22 AWG shielded twisted pair wire, 4000 feet (1200 m) maximum.
  • TTL: 22 AWG shielded twisted pair wire, 9 feet (2.9 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.
  • SAFR Expansion Port: Only connect certified SAFR Expansion products.
  • PoE: PoE 802.3af, Class 3; 13 watts.

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 should be grounded through earth ground to avoid issues arising from static electricity.

Tools Needed

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

4.3.2 Wiring

For all connections, do the following:

  1. Pull T1 or T2 8-pin connector from its slot to expose the screws that secure the wires.
  2. Strip wire ends about 1/8” and insert the connecting wires into the specified pins.
  3. Tighten the screws to secure the wires in place.
  4. Verify the wires are securely fastened.

Wire SAFR SCAN to PAC Panel as follows:

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 -

4.3.3 OSDP Termination Switch

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

4.3.4 Attach SAFR SCAN to Mounting Bracket

The square hooks on the top of the mounting bracket should be placed into the two square openings on the top of the SAFR SCAN housing first. Then the lower two openings placed onto the threaded tabs on the bottom of the mounting bracket as shown in the image on the left.

Holding the SAFR SCAN to the mounting bracket, push SAFR SCAN up and attached using the 2mm screws on the underside of the SAFR SCAN body as shown on right.

4.3.5 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.
