Double Foil Blocks for Alarm Foil Systems

Foil Block - Double
One block provides TWO screw terminals




  • UL listed for supplementary protection
  • Durable, clear polycarbonate base - just like the glass
  • Double Block - mounts directly on glass for fast reliable foil connection by using a strong, self adhering UL recognized double coated tape
  • If a single block is needed, break it off at the seam
  • Special nickel plated clips and screws provide maximum protection against corrosion
  • Each block has a lip on its side to protect the foil from slipping out of place, thus reducting ground shorts
  • Used to complete the circuit between the foil and any protective closed circuit alarm system




1. Decide the appropriate position for the foil block to be mounted on the window. When using the two sided foam tape, make sure the mounting surface is completely free of dirt, dust or grease before applying the tape.  Use a cleaner suitable for the mounting surface (on window glass, we recommend alcohol or a similar type cleaning solution)

2. Loosen or unscrew the two screws and attach the foil

3.  While the two screws are still loosened, connect the wires to each of the two screws and then connect the other end of the two wires to the N.C input of the alarm system.

4. Tighten the two screws
