DSC AMP-704 Installation Instructions Manual

AMP-704

Point Interface Module

INSTALLATION INSTRUCTIONS

The AMP-704 Point Interface Module (PIM) allows for the connection of non-powered or ex­ternally powered hardwired devices to the Addressable Multiplex Loop (AML). The four in­puts and cover tamper can be individually enrolled as zones on the control panel. The
module is jumper-selectable for either N/C loops, SEOL, or DEOL resistors .

The AMP-704 PIM uses a 2-wire connection for power and to communicate with the control
panel. This, in combination with low power devices, simplifies wiring and reduces installation
cost. The AMP-704’s low current draw also maximizes the number of modules that can be
connected to an addressable loop. For additional information on AML wiring, please refer to
the compatible panel’s Installation Manuals.

Mounting

Select a mounting location for the AMP-704. The module should be located in a dry location
and as close as possible to the points to be protected. Alternatively to the method explained
below, the PCB may be mounted in a metal cabinet using the standoffs provided with the
unit, refer to Figure 3.

1. Remove the cover using a flat blade screwdriver to push in the tab at the bottom of the
enclosure.

2. Pull the addressable loop and input wires through the wiring access holes located at the
bottom of the backplate.

3. Mount the device securely to the wall using the two mounting tabs on the backplate or
using the two mounting holes inside the backplate. To use the holes inside, the PCB must
first be removed. To do this, remove the 3 screws holding the PCB and lift it out.

CAUTION: When replacing the PCB, do not over-tighten the screws, the PCB
could be damaged.

NOTE: If the mounting tabs are not being used to mount the device, they can be broken off.

4. Wire the module and configure the EOL supervision jumper as per the instructions below.

5. Replace the cover and insert the cover screw.

CAUTION: Connect only DSC addressable devices to the addressable loop
connections. Connection of any other type of device will impair operation. Any
devices other than addressable devices that require power to operate must be
powered separately.

IMPORTANT: A minimum 1/4" (6.4mm) separation must be main-

tained at all points between battery/primary AC wiring and all other
wiring connections. The AMP-704 is mounted inside the compatible
control unit's enclosure using 3 nylon spacers 3/8" (9.6mm).
