2
The MC35 function provides a sequence for Relay 1 and/or
Relay 2 and/or Relay 3 triggered by Input 1 or ‘WET’ Input.
Simply put this function is a MC25 with three relays instead of
two. Adjustable parameters include
H1
for activation hold time of
Relay 1,
H2
for activation hold time of Relay 2,
H3
for activation
hold time of Relay 3,
D1
for delay between activation of Relay 1 to
Relay 2 and
D2
for delay between activation of Relay 1 to Relay
3. A re-activation of Input 1 or ‘WET’ Input before the sequence
expires will re-start all hold timers and keep the relays active.
A maintained input will freeze all 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.
A typical application is a secure pair of doors with flush bolts in
which you have a push-plate to start the sequence to unlock
the security device, such as a Maglock or electric strike, then
activate the first door controller and then activate the second
door controller. For this scenario the push-plate would be wired
to Input 1, the security device would be wired to Relay 1, the first
door controller would be wired to Relay 2 and the second door
controller would be wired to Relay 3.
NOTE: While the ‘WET’ Input is not involved in our typical
application, it will still function as Input 1 does if used.
MC35 SETUP
1. Wire the Br3 accordingly.
2. Select the MC35 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
35
.
3. Set the MC35 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 MC35 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.

H1
Relay 1 hold time
‘

’ - Relay 1 hold time will not begin counting down until the release of Input 1 or
‘WET’ Input.
H2
Relay 2 hold time
‘

Relay 1 and Relay 2 expires.
H3
Relay 3 hold time
‘

counting down with the activation of the sequence.
4. Once programming is complete, test the Br3. Trigger the sequence via Input 1 or ‘WET’ Input. Ensure that the 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,
R3
when Relay 3 is energized,
R=
when Relay 1 and Relay 2 are energized at the same time,
R
when all three relays are energized or
R=
when
Relay 1 and Relay 3 are energized at the same time.
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).
