Global clearing provides you with a quick fresh start if your
MCR-308 has been used in another system, or has been “played
with” as part of an experiment.
IMPORTANT! You must be prepared to perform the second
step of the following procedure within 10 seconds from the
first step, while the buzzer is still beeping.
A. Remove the cover from the MCR-308. Disconnect the power,
wait a few seconds and reconnect the power. This will cause
the buzzer to beep 10 times - 1 beep per second.
B . Within the limit of the above-mentioned 10 seconds, mount a
jumper across the two CLEAR pins, remove it immediately
and then mount and remove quickly again. When done, the
buzzer will start a series of rapid beeps, at the end of which
the “victory melody” (
) will sound. All transmitter and
expander IDs will thus be cleared from the memory.

If the transmitted ID has not been accepted (the buzzer remains
silent) although the memory location is free, try transmitting
again. If the second attempt is unsuccessful, the transmitter in
question may be faulty. Try enrolling another transmitter.

A . The location selected for the MCR-308 must constitute a
compromise between maximum reception ability and
minimum distance from the control panel.
B . The expanders may be located within the control panel’s
cabinet (if there is enough room) or near it.
C . It is very important to maintain the antenna vertical - the
receiver should be installed with the antenna on top, as
shown in Figure 2.
D . Avoid installing the MCR-308 on or near large metallic objects
such as closets, circuit breaker cabinets, air conditioner ducts
and fine-mesh window screens.
E . Do not locate the unit in close proximity to dense electrical
wiring.

To install the cabinet, proceed as follows:
A. Hold the base against the mounting surface and mark the
points for drilling (see mounting holes in Figure 2).
B. Drill the mounting holes and insert wall anchors if necessary.
Enter the wires into the base through the wiring holes or wiring
knockouts. Attach the base to the mounting surface with two
long screws.
C. Complete the wiring as described in Para. 4.3.

(Figures 5 and 6)
A. Connect the 4 zone outputs (1, 2, 3, and 4) of the MCR-308 to
the desired zone inputs of the control panel in use.
Figure 5. Wiring Diagram
B. Connect the four status outputs of the MCR-308 (TAMP,
INACT, L. BAT and JAM) to the desired zone inputs of the
control panel in use.
Note: If the control panel zone inputs are defined as E.O.L.,
you must use appropriate E.O.L. resistors (see Figure 6).
C. Connect the control panel’s 12 VDC (+) and (–) terminals to
their counterparts on the left edge of the MCR-308 module.
D. If an expander is mounted within the MCR-308 case, connect
it to the MCR-308 using the flat cable (supplied with the
expander) between the flat cable receptacles on both units. If
an expander is mounted away from the MCR-308 in a
separate enclosure, use the four bus terminals on both units,
connecting each terminal to its counterpart in the other unit

E. Make sure the antenna is firmly held in place near the top
edge of the PCB.

After wiring, it is necessary to set DIP switches 6, 7 and 8 as
required for the specific application (see Figure 7).
A. Make sure that SW-8 is OFF - the regular operation mode is
selected.
B. DIP switch SW-6 determines the zone output polarity (N.O. or
N.C.):
SW-6 Setting
Result
ON
The MCR-308 zone outputs are N.O.
OFF
The MCR-308 zone outputs are N.C.
Set the switch as required for your particular application.
C. DIP switch SW-7 determines the operating mode of zone
output No. 1 (Momentary or Toggle):
SW-7 Setting
Result
ON
Zone output 1 operates in the toggle mode
OFF
Zone 1 operates in the momentary mode
Note: Zone No. 1 can be used for Arming/Disarming purposes
or for other remote control tasks such as switching lights ON
and OFF.
Figure 7 can serve as a quick reference to DIP switch tasks.
