INSTALLATION INSTRUCTIONS

ADDENDUM

WI1278A 8/04

UL installations require front and back tamper switches to be in­stalled in the GEM-ACM1D. Use a GEM-TAMPERKIT and install
the switches into the GEM-ACM1D housing as detailed below:

Wire the Tamper Switches. To ease installation, wire the tamper
switches before mounting. Wire the switch terminals between termi­nal 11 (+ Tamper) and terminal 12 (- Tamper) in series, as follows:

1. Wire from GEM-ACM1D terminal 11 to terminal "A" on Wall
Removal tamper switch.

2. Wire terminal "B" to terminal "C" on the Cover Door Tamper
switch (see illustration below).

3. Connect terminal "D" to GEM-ACM1D terminal 12.

When wiring, be sure to have at least 1/4" between the

Note:

tamper wires, the flying battery leads and the wires that attach to
the GEM-ACM1D terminals 1 and 2. In addition, cut jumper J1 to
enable tamper.

Install Tamper Switches.

Mount each switch using three "6-32 x
7/8" screws (supplied). Note: Each GEM-TAMPERKIT is furnished
with two tamper switches, six machine screws and one self-tapping
screw to pre-tap the mounting holes.

1. Wall Removal Tamper: For a tamper alarm upon removal of
the enclosure from the wall, install one switch on the left side
wall (within the bracket cutout) with the switch button through

the hole in the rear wall (see illustration below).

2. Cover Door Tamper: For a tamper alarm upon opening of

the enclosure door, install the switch on the right-side wall with
the switch button facing the door. (Be sure to alert the user
that opening the door will cause a tamper alarm).

Install both switches as follows:

1. Be sure to tap the mounting holes using one of the self-tapping
screws (supplied) BEFORE installing tamper switches.

2. In PCD-Windows Quickloader Download software, program a
bell output on tamper as follows: In the Keypad Assignment
window, in the Keypad Reporting and Outputs tab, select the
area (from the drop down list) in which the ACM tamper is lo­cated to activate the Burglary output (see screen image below).

3. Place switch over mounting holes and insert mounting screws
starting from inside the housing, through the switch mounting
holes, and into the housing. Screw heads should be inside the
housing.

Select the area in
which the ACM
tamper is located.
Selection is high­lighted in red.
