8-Output Expander for the MCR-308 Receiver

. INTRODUCTION. INTRODUCTION

1.1 General Description

The MCX-8 is an 8-output expander unit especially designed to
increase the number of outputs of the MCR-308 PowerCode
wireless receiver.

Up to three MCX-8 expanders, with 8 outputs each, can be
connected to the MCR-308 (see Figure 1). The expanders
communicate with the receiver via a 4-wire power/data bus.

Figure 1. Full System Configuration - MCR-308 with 3 Expanders

Each expander is identified by a factory programmed 8-bit ID
number. This ID must be registered in a specific memory location
of the MCR-308 to which the expander is connected (see
Publication DE3191-).

The communication link between the MCX-8 and MCR-308
receiver is continuously monitored (every 5 seconds) by the
MCR-308 receiver. In case of communication failure, the inactivity
output of the receiver will be activated.

Installation Instructions

units are installed in the same cabinet, only one tamper switch is
used (the one of the unit to the right).

Important! You must bridge the two TAMP terminals of the left­mounted MCX-8, but be sure to do it only after having
conducted a “teaching” session (as instructed in the MCR-308
manual, Publication DE3191-).

1.2 Construction and Packaging

The MCX-8 printed circuit board is enclosed in a plastic cabinet
that facilitates installation on a flat surface and protects the unit
against tampering. The cabinet can be separated into two parts:
the cover and the base (see Figure 2). Disassembly instructions
are given in Para. 3.1.

Figure 2. Plastic Cabinet

The base can accommodate a single MCX-8 module (Figure 3) or
two side-by-side MCX-8’s (Figure 4) or an MCR-308 receiver unit
alongside the MCX-8 (Figure 5). Various mounting and wiring
knockouts are provided (see

Tamper protection is accomplished with an on-board tamper
switch, actuated upon removal of the front cover (Figure 6). If two

3.1 Mounting

The MCX-8 is supplied in a plastic cabinet, as described in Para.

1.2. Install the plastic cabinet as follows:
A. Remove the screw that

secures the cover to the
base (Fig. 6).

B. Insert a small screw-

driver blade into the slot
near one of the snap-in
tabs, as shown. Carefully
flex the cover edge out,
until the tab disengages
the dent. Repeat this
with the other tab.

from the Base

C. Remove the cover and use the mounting and wiring holes as

required for the particular installation.

3.2 Expansion Bus Hookup

Since the MCR-308 receiver and the MCX-8 expander usually
share the same cabinet, the easiest way to link them is to use the
short flat cable assembly supplied with each MCX-8 (Figure 7).
To continue the bus to additional expanders, use the 4 bus
terminals on each unit (refer to Figure 1). Connect each terminal
on the bus terminal block to its counterpart on the other unit.

Tamper Switch Ratings: 0.1 A, 30 VDC
Input Voltage: 10 -16 VDC (supplied via the expansion bus).
Current Drain: Approximately 7 mA standby, 13 mA maximum.
Operating Temperature Range: -10°C to 49°C (14°F to 120°F).
Size (H x W x D): 108 x 165 x 38 mm (4-1/4 x 6-1/2 x 1-1/2 in.)
Weight (cabinet with single MCX-8): 191 g (6.75 oz).

no pressure is applied on the actuating lever of the built-in tamper
switch - remove the circular spring if necessary.

3.3 Output Circuit Wiring

After connection via the expansion bus to the MCR-308, the MCX-8
will have a common ground with the control panel via the MCR-308.
You only have to connect each output terminal of the MCX-8 to one
of the control panel’s zone inputs.
If the control panel zone inputs are defined as E.O.L., you must
use appropriate E.O.L. resistors (see Figure 8).

3.4 Using an External Tamper Switch

The built-in tamper switch and the TAMP terminals are connected
in parallel. If the external TAMP terminals are used, make sure that
