The MC65 function provides a two-way sequencer to sequence
Relay 1 and/or Relay 2 triggered by Input 1. Similarly, it also
provides a sequence in the opposite direction to sequence
Relay 2 and/or Relay 1 triggered by Input 2. Inputs 3 and 4 also
trigger Relays 1 and 2 individually (non-sequenced). Adjustable
parameters include
H1
for activation hold time of Relay 1,
H2
for
activation hold time of Relay 2,
D1
for delay between activation
of Relay 1 to Relay 2 and
D2
for delay between activation of
Relay 2 to Relay 1. A re-activation of Input 1 or Input 2 before
the sequence expires will re-start both hold timers and keep the
relays active. A maintained input will freeze both hold timers,
thus keeping their relays active until the input is released, which
will allow the hold timers to expire and deactivate the relays
normally.
NOTE
: The delay timer will only fire one time during initial
activation or maintained input.
NOTE: The functionality for MC65 has changed slightly in this
version as you no longer have to wait for a sequence to
complete before running another sequence.
A typical application is an unsecured two door sequence vestibule
that allows two-way traffic in which you have a push-plate on the
entrance of each door to start the sequence and two push-plates
between the doors to activate the doors individually in case of
entrapment. For this scenario the push-plate for in-bound traffic
would be wired to Input 1, the push-plate for out-bound traffic
would be wired to Input 2, a push-plate for entrapment release
of door 1 would be wired to Input 3, a push-plate for entrapment
release of door 2 would be wired to Input 4, Relay 1 would be
wired to door controller 1 and Relay 2 would be wired to door
controller 2. An example wiring diagram for this scenario is shown.
MC65 SETUP
1. Wire the Br3 accordingly.
2. Select the MC65 as the function according to the steps outlined in Section 5 – Selecting the Function.
• Press and hold both push buttons (INCR & PARAM) for three (3) seconds to activate the display.
• Press the INCR button to toggle through each function and select
65
.
3. Set the MC65 parameters according to the steps outlined in Section 5 – Selecting the Function.
• Press PARAM button to cycle through and set the parameters.
• Press the INCR button to increment the parameter’s value.
Parameters for the MC65 function are shown in the chart. Set the parameters as needed for the application, and wait for the display to
become inactive to save the configuration.

for inbound or until the delay between Relay 2 and Relay 1 expires for outbound or until
the release of Input 3.
H2
Relay 2 hold time
‘
00
’ through ‘

for outbound or until the delay between Relay 1 and Relay 2 expires for
inbound or until the release of Input 4.

4. Once programming is complete, test the Br3. Trigger the sequence via Input 1. Ensure that the in-bound sequence runs and the relays
activate and the timers are as programmed. The display will show
R1
when Relay 1 is energized,
R2
when Relay 2 is energized and
R=
when
both Relay 1 and Relay 2 are energized at the same time. Trigger the sequence via Input 2. Ensure that the out-bound sequence runs and
the relays activate and the timers are as programmed. Trigger only door 1 via Input 3. Trigger only door 2 via Input 4.
5. Upon completion of the above steps, walk test the door to ensure all functions, timers, sensors, etc. are working as intended and that the
system is in compliance with all applicable standards (i.e. ANSI A156.10, A156.19).
