Digital Key Switch  (490-0535A)     Installation       Faxback Doc. # 6864

Installation Hints

  Before installing the Digital Key Switch, make temporary connections
  between the alarm system and the Digital Key Switch to confirm proper
  operation.  If you have problems, see Faxback document # 6865.

  Install the Digital Key Switch indoors where it will not be subjected
  to dust, dirt, or extremes in temperature or humidity.

  Set the LATCH IN/OUT switch before power is connected to the Digital
  Key Switch.

1.  Select a location on the wall that is next to a wall stud.

2.  Using a single-gang electrical box as a template, make a hole just
    large enough to accept the electrical box.

3.  Run the necessary wires from the alarm system to the hole (through
    attic, walls etc.) and through one of the knock-out plugs in the
    electrical box.  Be sure to leave enough extra wire to allow for
    connection to the Digital Key Switch.

4.  Insert the box into the hole and nail it to the wall stud; the box
    should be recessed slightly below the surface of the wall.

5.  Connect the wires to the Digital Key Switch terminals, as described in
    the manual.  Be sure to avoid stray wires that touch other terminals
    or the other sides of the box.

6.  Carefully push the wires into the box and attach the keyboard portion
    of the Digital Key Switch to the box using the two supplied screws.

7.  Hang the Digital Key Switch cover plate at the top of the Digital Key
    Switch and secure it at the bottom using the supplied set screw.

Note:  The cover plate holds in the tamper switch plunger.  If the tamper
       switch is connected to a 24-hour panic/tamper loop on your alarm,
       the alarm will be tripped if the cover plate is removed, even if
       the alarm is not armed.
