The LE22 function provides a sequence for Relay 1 and/or Relay
2 with an inhibitor of activation for 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. Adjustable parameters
include
H1
for activation hold time of Relay 1,
H2
for activation
hold time of Relay 2 and
D1
for delay between activation of
Relay 1 to Relay 2. A re-activation of the sequence before it
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 door position switch must have a closed
contact when the door is closed and an opened
contact when it is not.
A typical application is a ‘Low-Energy’ situation, which needs
security, in which you have only ‘Knowing-Act’ activation
devices such as push-plates and a re-activation device, such
as a SuperScan, on the door for safety and a door position
swtich. For this scenario the push-plates would be wired to
Inputs 2 and/or 3, the SuperScan would be wired to Input 1,
a door position switch on Input 4, a security device such as a
Maglock or electric strike on Relay 1 and the door controller on
Relay 2. When the door position switch on Input 4 is closed,
the SuperScan input is ignored (inhibited) and only becomes a re-activation device (uninhibited) after an activation on Input 2 or Input 3. The
SuperScan on Input 1 will remain uninhibited until the door is closed again closing Input 4. An example wiring diagram for this scenario is shown.
NOTE: While the ‘WET’ Input is not involved in our typical application, it will still function as Input 2 and Input 3 do if used.
LE22 SETUP
1. Wire the Br3 accordingly.
2. Select the LE22 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
22
.
3. Set the LE22 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 LE22 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.

’ seconds. The delay time will begin
counting down with activation of sequence.
4. Once programming is complete, test the Br3. Attempt to trigger the sequence via the re-activation device tied to Input 1. Ensure that
the sequence does NOT start as it should be inhibited. The display should still show
22
since Relay 1 is de-energized. Now trigger the
sequence via Input 2, Input 3 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 or
R=
when both Relay 1 and Relay 2 are energized at the
same time. Before the door closes attempt to re-activate the sequence via the device tied to Input 1. The door should re-open immediately
and the relay hold timers should restart. Once again observe the relay hold times and ensure that it is as programmed. Let the door close
and trigger Input 4 via the door position switch. Once again attempt to trigger the sequence via the re-activation device tied to Input 1.
Ensure that sequence does NOT start as it should be re-inhibited.
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).
