MCR-304
Wireless Interface for Hard-Wire Control Panels
1. INTRODUCTION
1.1 Purpose and Use
The MCR-304 is a single output wireless
PowerCode / CodeSecure™ receiver designed
to add fully supervised wireless capabilities to
hard-wired control panels, as demonstrated in
Figure 1.
The MCR-304 can be connected to various
control panels for remote control purposes and
can use up to 10 Powercode / CodeSecure™
wireless devices for remote control.
The MCR-304 will recognize only those
devices with IDs that have been "taught" into its
non-volatile memory. Other devices will be
ignored.

Paragraphs 3.4 and 3.5.
The MCR-304 provides trouble, low battery and tamper outputs
which are common to all 10 wireless devices.
1.2 Control Output
The MCR-304 features a single FORM-1C relay output that
reacts to control signals received from up to 10 wireless detectors
or hand-held transmitters. The relay can be programmed to
operate in the Pulse or Toggle modes (see Para. 4.4 for full
details).

1.3 Status Outputs
In addition to the single relay output, the MCR-304 provides 3 open-
collector status outputs that function as follows:
Tamper: This output is activated once a TAMPER state is
detected in a transmitter or in the MCR-304 receiver itself.
Low Battery: This output is activated whenever a low battery
message is received from one of the detectors/transmitters.

Installation Instructions
Replacing the battery in the transmitter that sent the low-battery
message and transmitting once again resets the output.
Trouble: This output is activated if a supervised transmitter fails
to send its attendance message within a 4-8 hours time frame.

1.5 Receiver Operating Modes
Two operating modes are available:
OPERATE - normal position (receiver stands by for signals)
LEARN - enrollment of transmitter IDs in the MCR-304
memory.
1.6 LED Functions during Operation
SIGNAL indicator (red - visible through a hole in the cover):
This LED illuminates when the output relay is energized and
continues to light for as long as the relay remains energized. The
LED extinguishes when the relay drops out.
Note: The red LED has a different function during the learning
session (see Paragraphs 3.4 and 3.5).
Memory Location indicator (yellow - visible only when the
cover is removed): This LED is extinguished in normal operation,
but has a special function during the "learning" session.
Tamper Switch Ratings: 0.1 A / 30 VDC.
Input Voltage Range: 10.5-16 VDC (MCR-304) or 24 VAC/DC
(MCR-304U)
Current Drain (@ 12 VDC): 7 mA (standby), 32 mA (relay
energized).
Compliance with Standards:
ETS 300683).
