3.1.3 The contractor will supply & install four (4) safety loop sensors. The four sensors or “safety loops” will be positioned at the front and the back of each barrier on RAF Molesworth. One sensor shall be positioned at each entry and exit point of the barrier “Inner Safety Loop” and Outer “Safety Loop” at each AVB system. The safety sensors shall be placed in a manner that enables a 4 second safety delay with applicable safety features as outlined in UFC 4-022-01.

3.1.4 Photocells shall be installed at the barriers. The photocells shall be signal device and receive device. No reflectors shall be used to “reflect the signal.”

3.1.5 The system shall be fully integrated with traffic lights located at the active barrier. The safety scheme will operate as listed: Four second safety delay:

Once the button is pushed, the traffic light turns to red for four (4) seconds and the vehicle detection loops check for the presence of a vehicle. If no vehicle is detected, the AVBs raise rapidly and must be fully open in 2 seconds or less.

3.1.6 The contractor shall provide and install a single control panel at the main entry point which allows for both barriers to be controlled independently.

Once the push-button has been depressed, the system shall automatically deploy until the barrier is fully raised or lowered. See item 3.1.2. All ECPs shall have the same control panel operation and setup for entry controller operability.

Fault indicators showing operation errors The push-buttons should flash to indicate which direction the barrier is operating Control panel shall include connections for future AVB/crash rated drop arms.
