4.2 Mounting the Base in Place
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 knockouts.
Attach the base to the mounting surface with two long screws.
C.
Complete the wiring as described in Para. 4.3.

4.4 Customizing Your Receiver
After wiring, you must set the relay output operating mode in
accordance with the requirements of your specific application.
Note:
The relay output of the MCR-304 may be used for remote
control tasks such as opening / closing a garage door.
The PULSE / TOGGLE jumper determines the operating mode of
the MCR-304 output relay (Pulse or Toggle):
PULSE MODE
Upon reception of a valid transmission, the output
relay pulls in for as long as the transmission is
received, plus 3 seconds. The relay will drop out
when the “pulse timer” completes its countdown.
Note:
If another valid transmission is received during countdown,
the pulse timer will be automatically reset and a new countdown
will begin.
TOGGLE MODE
The output relay changes state each time it receives
a valid transmission. Upon entering a new state, the
toggle circuit is inhibited for 3 seconds, to impose a
3-second interval between states.
Note:
If another valid transmission is received during the 3-
second inhibit period, the inhibit timer will be automatically reset
and a new 3-second period will begin.
5. MISCELLANEOUS COMMENTS
5.1 The Effect of Transmitter Type on
Output Relay Function in the PULSE
Mode
U
pon receiving a signal from one or several restoral- reporting
transmitters, the MCR-304 will energize its output relay and will
keep it this way until all transmitters signals restore.
Note:
If the system includes
restoral reporting transmitters, it is
not recommended to set the MCR-304 to the toggle mode.
5.2 The Effect of Transmitter Type on
the TRB (Trouble) Output
The MCR-304 makes a distinction between supervised and non-
supervised transmitters.
Supervised transmitters transmit an “attendance message” at
regular intervals. If such a transmitter fails to send this message
on time, the MCR-304 will activate its TRB (trouble) output.
On the other hand, failure to receive an attendance message
from a transmitter identified as a non-supervised device will be
ignored by the MCR-304.
5.3 Product Limitations
Visonic Ltd. wireless systems are very reliable and are tested to
high standards. However, due to their low transmitting power and
limited range (required by FCC and other regulatory authorities),
there are some limitations to be considered:
A.
Receivers may be blocked by radio signals occurring on or
near their operating frequencies.
B.
A receiver can only receive one transmitted signal at a time.
C.
Wireless equipment should be tested regularly to determine
whether there are sources of interference and to protect
against faults.
