8-Relay Output Adapter for the MCR-308

,1752'8&7,21

The RL-8 is an ”open collector t o dry contact” adapt er, designed
as an interface unit between t he output s of t he MCR-308 wi r eles s
receiver and alarm c ontrol panels or remote c ontrolled devices.
Similarly, the RL-8 can serve as a suitable output interface for
other electroni c security devices that have open-col lector outputs.

The benefit offered by the RL-8 is the ability to overcome feat ures
imposed by open collector outputs - the current limit and the
“pull-to-gr ound” action - both of which ar e undesirable in certain
applications.

The 8 on-board relays of the RL-8, with normally open (N.O.)
contacts, c an control up t o 8 zones of an alarm cont rol panel, or 8
different electronic devices, or a combination of both.

When activat ed by PowerCode mess ages, open coll ect or output s
of the MCR-308 energize the associated relays on the RL-8
board. The relay contacts close, thus closing the circuit int o which
they are wired (see Fi gure 1).

Operating power for the RL-8 is obtai ned from the same source
that supplies input vol tage to t he MCR-308. The RL-8 is sold as a
”bare” module, but can be housed in the MCR-308 cas ing, next to
the MCR-308 printed circuit board (see Section 3).

The RL-8 module may be mounted in any host c abinet, provided
that 6 mm (1/4”) cl earance is left bet ween the bottom sur face of
the printed circuit board and the cabinet wall. This is easily
achieved by using cyli ndric al plas tic bushi ngs as spacer s t hrough
which mounting screws are inserted.

It is sometimes preferable to mount the RL-8 in the MCR-308
case (see Figure 2). I f this is done, t he RL-8 will be protect ed by
the same tamper switc h used to protect the MCR-308. Open the
MCR-308 case as shown in t he MCR-308 installation instructions,
and clip off the 2 plastic standoffs indicated in Figure 2.

After that, place the RL- 8 as shown in Figure 3 and attach it t o
the upper standoffs with two screws.

Each relay operating c oil in t he RL-8 i s per manent ly c onnec ted t o
the 12V terminal of the unit. Applying 12 VDC (+) to the 12V
terminal therefore maintains one end of each coil at 12 V (+)
potential. Each relay will be energized if the other end of it s c oil is
grounded through the appropri ate input. If wiring i s complet ed as
in Figure 4, and provided that the MCR-308 out puts are defined
as normally open (N.O.), the other end of the c oil will be pulled to
ground by the respective open-collector output of the MCR-308.

terminal and any one of

input terminal of the RL-8.

Note: To prevent confusion, it is recommended to connect
each output to the cor respondingly numbered input: Output 1
to Input 1, Output 2 t o Input 2, and so on.

IMPORTANT! If the open collector outputs of the MCR-308
have been defined as normally closed (N.C.), each relay
controlled by such an output will be permanently energized
(fail safe). This means that the relay contacts will be
permanently closed, and will open only upon de-activation of
the respective open-c ollect or output by wireless signali ng or
by power loss.

Connect the output terminals of each relay to the corres-

C.

ponding zone input of the alarm c ontr ol panel. Figure 4 shows
just one output connected as an example. All other 7 outputs
may be similarly wired. Remember to connect an E.O.L.
resistor of the correct value, as required for the particular
control panel (see Figure 5).

Note: The output relay contacts may also be wired to switch

auxiliary electronic devices on and off. This application does
not require E.O.L. resistors.
