Wireless Interface for Hard-Wire Control Panels
Installation Instructions
1. INTRODUCTION
1.1 Purpose and Use
The MCR-308 is a wireless PowerCode receiver designed to convert
a regular hard-wired control panel into a hybrid wireless system, as
demonstrated in Figure 1.
MCR-308T (868.95MHz) is an MCR-308 that includes an "underboard" tamper switch that opens if the unit is forcibly removed from
the mounting place. In this case, a tamper message is transmitted.
MCR-308T RL is an MCR-308T with an 8-relay interface (RL-8) for
dry contact outputs.
MCR-308T & MCR-308T RL include 2 diversity antennas - allowing
high performance reception, overcoming "in-band" interference.
The unit provides 8 open collector outputs - 4 zone outputs and 4
status outputs (see Para. 1.3 for details). With the MCR-308 serving
as an interface between wireless transmitters and the control panel,
the control panel’s zone inputs “see” regular wired loops, as if they
were directly connected to hard-wired devices. The states of the
receiver outputs (open circuit or closed circuit) determine whether the
control panel’s zone inputs are in alarm or not.
Figure 1. Typical Application of the MCR-308
A notable feature of the MCR-308 is its compatibility with both regular
PowerCode and Code-Secure™ transmitters. Code secure™
transmitters are mainly used to arm/disarm an alarm system or in
other control applications, to prevent “code grabbing” by people with
malicious intents.
Three operating modes are available:
Normal - the receiver stands by for regular reception
Learn - Enrolling transmitter and expander IDs to the MCR-308
memory (see Para. 1.4).
Test - allows the installer to test the system.
1.2 Expansion Option
Although the MCR-308 provides only 4 zone outputs, its span of
control can be increased by adding up to three MCX-8 expander
modules, connected via a 4-wire expansion bus (see Figure 2).
Full data on the MCX-8 is given in Publication DE4050-.
Figure 2. Expanded System Configuration
Each expander provides 8 additional outputs, and together with the 4
zone outputs of the MCR-308 the total number of zone outputs will
amount to 28. Twenty eight zone outputs multiplied by four wireless
devices per output produce a total of 112 differently coded wireless
devices that can be used in a single system.
1.3 Available Outputs
A. Zone Outputs
The MCR-308 features 4 open-collector zone outputs (expandable to 28
outputs - see Figure 2). Up to 4 transmitters/ detectors can be enrolled
to each zone output (see Para. 1.4).
DE3191 1
For MCR-308 T only, when the alarm system is disarmed the zone
output of the transmitted message is activated if a supervised
transmitter fails to send its attendance message within 8 min. In
addition, the zone output of the transmitter / detector with low battery
condition, will be activated within the first two minutes after the armed
system is disarmed.
B. Status Outputs
In addition to the 4 zone outputs, the MCR-308 provides 4 opencollector status outputs that function as follows:
Tamper: This output is activated once a TAMPER state is
detected in a transmitter, in an expander unit or in the MCR-308
receiver itself. In addition, (MCR-308 T only), when the alarm
system is armed this output is activated once a supervised
transmitter fails to send its attendance message within 4-8 hours.
Inactivity: This output is activated if a supervised transmitter fails to
send its attendance message within 4-8 hours, and also upon
sensing expander inactivity for 10 seconds.
Low Battery: This output is activated whenever a low battery
message is received from one of the transmitters/detectors. The
output is reset by replacing the battery in the transmitter that sent
the low battery message and transmitting once again.
Jamming: This output is activated if an interference (channel
jamming) is detected on the RF channel for more than 30
seconds. It is reset a few seconds after the jamming stops.
C. Optional Dry-Contact Interface
An 8-relay interface unit - the RL-8 - complements the MCR-308
where dry-contact outputs are required. For such applications we
recommend the MCR-308/RL, a combined product in which one
MCR-308 and one RL-8 are interconnected in the factory and
mounted within a common housing.
The RL-8 can also be used in conjunction with the MCX-8 expander
to convert the expander’s open-collector outputs into dry-contact
outputs. For such applications we recommend the MCX-8/RL, a
combined product in which one MCX-8 and one RL-8 are interconnected in the factory and mounted within a common housing.
Full data on the RL-8 interface unit is given in Publication DE5712-.
1.4 Enrolling Capability
For proper operation, the MCR-308 must recognize the ID code of
each wireless transmitter used in the system and of each MCX-8
expander added to the system. Each transmitter must be enrolled to
the actual zone output it is meant to trigger (up to 4 transmitters per
zone output), and each expander (if used) must be also be enrolled to
the MCR-308. Transmitter and expander enrolling procedures are
given in Paragraphs 3.5 and 3.6
.
1.5 Construction Details (Figure 3)
The MCR-308 is packaged in a two-part plastic cabinet, with vacant
space for an MCX-8 expander module (that adds 8 outputs to the
receiver) or the RL-8 dry contact interface unit (that converts the open
collector outputs into dry contact outputs).

3. PROGRAMMING
3.1 Helpful Hints
A learning session is required to let the MCR-308 learn the ID codes
of individual wireless transmitters and link each transmitter to a
specific output (up to 4 transmitters per output).
In addition, it is necessary to register in the receiver’s memory the ID
code of any MCX-8 expander used in the system. If these codes are
not “learned”, the expanders will not function.
The quickest way to conduct a learning session is on a work bench, with
every transmitter you need within reach, and where you may observe
the receiver’s indicator LEDs and listen to the buzzer.
3.2 Initial Steps
A. Remove the screw that secures the cover to the base and remove
the cover as shown in Figure 4.
Figure 4. Removing the Top Cover
Some variants use a semi-rigid vertical antenna that extends out of
the housing. Other variants use an internal wire antenna.
1.6 LED Tasks in Normal Operation
The MCR-308 has two LED indicators:
• SIGNAL indicator (red)
• TROUBLE indicator (yellow)
SIGNAL indicator: This LED lights steadily for 2 seconds upon
reception of a valid message. If noise or unrecognizable RF signal
are received, the LED flickers.
TROUBLE indicator: This LED is extinguished while all is well, but
lights steadily for as long as the TAMPER, LOW BATTERY and
INACTIVITY outputs are activated.
The trouble indicator will remain lighted until all trouble is cleared
(restore/attendance messages arrive from all trouble sources). To
find out which zone is “in trouble”, see Para. 4.6.
Note: Both indicators have other functions during a learning session
(see Paragraphs 3.5 and 3.6).

inner part of the cover. Detach the antenna from its storage position,
insert its straight tip into the antenna terminal and tighten the screw
well. See Figure 3 for antenna terminal location.
C. Gather up all transmitters used in the system and mark each one
according to the desired deployment plan.
D. Temporarily power up the MCR-308 by connecting a 12 V battery
or a 12 VDC power supply across its 12 V input terminals.
Observe polarity!
3.3 Selecting the Zone Output
In order to enroll a transmitter to a specific zone output, you must first
select the desired output number by setting DIP switches SW1
through SW-5 as shown in Table 1. A (–) sign indicates an off position
of the switch.
