MCR-304
Wireless Interface for Hard-Wire Control Panels
Installation Instructions
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.
Detailed teaching/learning procedures are provided in
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).

Typical Application of the MCR-304
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.
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.
1.4 Construction Details
For construction details, refer to Figure 2.

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.
