The Br3 is a programmable 3 relay logic module that may be used for 

multiple applications, including simple timing, door mounted sensor 

inhibiting and advanced relay sequencing. The Br3 contains 12 

different programmable functions which allow the technician to carry 

one and only one module.

In addition to the ability to provide up to 3 Amps through the first 

two relays and 1 Amp through the third relay used in ‘‘DRY’’ mode, 

the Br3 provides the ability to select a ‘WET’ voltage output of 

up to 1 Amp on Relay 1 to power electric strikes and magnetic 

locks without the need for an external power supply. This feature 

can greatly simplify the installation (as long as the power supply 

powering the Br3 is rated for 1 Amp).

The ‘WET’ output can also be set using jumpers to output DC if the Br3 is supplied with AC, otherwise it will just pass the AC voltage that is 

supplied. Similarly if powered by DC, the ‘WET’ output will only output DC.

The module provides removable screw terminal connectors which help to reduce extra wiring.

Another feature of the Br3 is that it also provides an easy 2-button digital programming with a user-friendly display, hold times being adjustable 

from 0 to 60 seconds, and delay times being adjustable from 0 to 60 seconds with ¼, ½ and ¾ also available to the applicable functions.

FUNCTION SUBJECT

DESCRIPTION

PAGE

1 0

(MC10)

Simple Timer

Provides an activation of Relay 1 triggered by Input  1. The function also provides an option for 

reverse-logic on the activation of Input 1.

4

1 1

(MC11)

Ratchet/Latching

Provides a ratcheting/latching of Relay 1 triggered by Input 1.  Each trigger of Input 1 will change the 

state of Relay 1.

4

2 1

(LE21)

Inhibitor w/Door 

Position Input

Provides an activation of Relay 1 with an inhibitor of activation of  Input 1 until Input 2, Input 3 or 

‘WET’ Input is triggered, which all activate Relay 1. Additionally Input 4 provides a door position switch 

input for which closing it will re-inhibit Input 1.

5

2 2

(LE22)

2 Relay Sequence 

Inhibitor w/Door 

Position Input

Provides a sequence for Relay 1 and/or Relay 2 with an inhibitor of activation of Input 1 until Input 

2, Input 3 or ‘WET’ Input is triggered, which all activate the sequence.  Additionally Input 4 provides 

a door position switch input for which closing it will re-inhibit Input 1.  Simply put this function is a 

combination between a LE21 and MC25.

6

2 5

(MC25)

2 Relay Sequence Provides a sequence for Relay 1 and/or Relay 2 triggered by Input 1 or ‘WET’ Input. 

7

2 8

(MC28)

2 Relay Sequence 

w/Door Position 

Input

Provides a sequence for Relay 1 and/or Relay 2 triggered by Input 1 or ‘WET’ Input.  Additionally Input 

2 provides a door position switch input which allows the delay to run when Input 2 is opened, but not 

run when closed.  Simply put, this function is an MC25 with a normally opened door position switch 

input to determine if the delay should run.

8

2 9

(MC29)

Relay 1 

Deactivation 

Timer

Provides a sequence for Relay 1 and/or Relay 2 triggered by Input 1 or ‘WET’ Input.  Additionally Input 

2 provides a door position switch input which allows Relay 1 to deactivate once Input 2 is opened after 

the sequence has run.  Input 2 also allows the delay to run when Input 2 is opened, but not run when 

closed, as in the MC28.  Input 3 provides an input to disable the sequence whose input logic is also 

selectable.  Simply put Relay 1 will be active the entire time until the normally opened door position 

switch signifies that the door has come closed again.

9

3 5

(MC35)

3 Relay Sequence 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.

10

5 0

(MC50)

Interlock Timer 

w/Door Position 

Inputs

Provides an interlock of Relay 1 and Relay 2 triggered by Inputs 1 and 2, with door position switch 

inputs on Input 3 for Input 1and Input 4 for Input 2.  Only one relay will be allowed to operate at a 

time thus making the two relays interlocked or mutually exclusive.  In order to activate a relay, its 

corresponding position switch input must be closed.

11

5 5

(MC55)

Interlock Ratchet 

w/Door Position 

Inputs

Provides an interlock ratchet of Relay 1 and Relay 2 triggered by Inputs 1 and 2, with door position 

switch inputs on Input 3 for Input 1 and Input 4 for Input 2. Only one Relay will be allowed to operate 

at a time thus making the two relays interlocked or mutually exclusive.  In order to activate a relay, its 

corresponding position switch input must be closed. Each trigger of an input will change the state of its 

respective relay. 

12

6 5

(MC65)

2-Way, 2 Relay 

Sequence

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.  

13

7 5

(MC75)

2 Relay Sequence Provides a sequence for Relay 1 and/or Relay 2 triggered by Input 1 or ‘WET’ Input.
