1 Introduction

The Wireless Optic Fiber Seal (WOFS) has been developed to support the Global Threat
Reduction Initiative mission of securing radioactive material. Once installed, WOFS will prevent
unmonitored access to essential equipment or materials. This guide provides installation and
maintenance instructions for the WOFS system.

2 Concept of Operation

The WOFS system consists of a WOFS Receiver (see Figure 1) in wireless communication with
a WOFS Transmitter (see Figure 2). The Transmitter is connected to a loop of fiber optic cable
that will be wrapped around or through the object to be sealed. Sealed objects can include
equipment racks, panels, doors, or drawers.

If the fiber optic cable is broken, WOFS will trigger an alarm indicating that the seal has been
compromised. The WOFS is also equipped with a security features to resist attempts to “spoof”
the optical signal.

3 Installation of the WOFS Receiver Hardware

The WOFS Receiver can communicate with up to eight Transmitters (see Figure 3). The
Receiver is typically connected to an alarm panel or to the Integrated Remote Monitoring System
(iRMS).

 When the WOFS Receiver is integrated with an iRMS, WOFS supports a user interface at

an operator security station that shows WOFS health, location of alarm, camera video,
and the iRMS can send email and text message notifications.

NOTE: Connecting the WOFS to an alarm panel or to an iRMS will be covered in
Section 5. The functionality of the LEDs and buttons will be covered in Section

14.

Connecting Power

The Receiver is powered by +12 VDC supplied by the facility where the Receiver is installed.

1. Connect power to the terminals by removing the 4 recessed, Phillips-head screws and
open the case to access the terminal blocks.

2. Turn off the source of the facility’s +12VDC.

3. Connect +12 VDC wire and ground wire to Receiver’s DC Power terminals. Run the
wires across the Strain Relief Zip ties, and through the hole next to the SMA antenna
connector (see yellow-highlighted boxes in Figure 4).

4. Connect the +12VDC wire and ground wire to the facility’s power source, following
NEC guidelines.

NOTE: Do NOT turn on the power source until all of the wiring process is
complete, as instructed later in this manual.

4 Connecting the Receiver to the iRMS Using the Smart

Digital Interface

1. On the WOFS Receiver, attach a Ground wire to the Smart Digital Interface (SDI)
Terminal Block to the location labeled GND (see yellow boxes in Figure 5).

Figure 5 - Smart Digital Interface terminal block

2. Open the iRMS unit.

3. Attach the other end of the Ground wire to Terminal Block J8, at location screw #14 (see
Figure 6). For more information, refer to the CHCT manual.
