INSTALLATION INSTRUCTIONS
1. Ideally, it is best to mount each EMS5 Call Director™ side by side. This will reduce
field-wiring problems.
2. Use the 3-Keyholes on the back-box case of the EMS5 to mount the unit on a dry or
concrete wall. The back-box case could be used as a template to mark the 3 holes
on the wall before drilling. When mounting the EMS5 unit the two-keyholes should
be on top. We recommend but not supply #6 (6-32) or #8 (8-32) wall screws for
mounting. (see mounting Diagram for more info)
•NOTE: WE DO NOT RECOMMEND MOUNTING THE CASE OF THE EMS5
CALL DIRECTOR ON THE CONTROLLER OR ON A METAL SURFACE THAT
SHORTS TO BUILDING GROUND TO AVOID INTERFERANCE / NOISE.
IF ONLY ONE EMS5 IS BEING INSTALLED, PROCEED TO STEP 5
3. Multiple EMS5 units will be shipped with the units setup to operate as the primary
(first) through to the secondary EMS5 unit(s) (last or eighth). They should be
mounted in the same machine room from left to right, starting with the first EMS5
on the left, the second unit to the right, third unit to the right of the second, etc.
through to the last or eighth unit allowing at least 15 inches between units.
4. If the EMS5 units are not identified with a number to indicate which is the first
(primary), through the last or eighth (secondary), follow these steps:
a. Any EMS5 can be switched between being a primary unit and a secondary unit by
programming a simple programming command.
b. Perform this step after the EMS5 is powered up. If you have a secondary unit
and need to make it a primary unit, you can use the keypad or call into the unit
to program it. (See accessing programming mode section on page 6)
c. Perform this step after the EMS5 is powered up. If you have a primary unit and
need to make it a secondary unit or change the number (order) of the
secondary, disconnect it from the other units and press the reset button. Go into
programming mode (See Accessing programming mode section on page 6) and
enter * 6S # where “S” represents the number (order) of the secondary unit.
Example:*61# (second unit), *62# (third unit), etc…
After three beeps enter # # to end programming. Listen for six beeps. Hang up
the handset. Re-connect the EMS5 to the other ones in the group using the
wiring diagram of this manual and then press the reset button. Continue by
pressing the reset button on the rest of the units in a sequential order from the
last to the first unit. After you reset all the units the ‘COM ERROR’ light should be
‘OFF’ on all the units in the group.
Note: If the ‘COM ERROR’ light is ‘ON’ on any of the units check the cables that
connect the units together.
5. Open up the front cover of the unit by removing the two screws on the sides of the
unit.
