General Description
The CX-22 is a dual function relay. Specifically, it is
a Washroom Door Controller, and a Bi-Directional
Door Sequencer. It is designed to be versatile yet
user friendly with easy to understand terminology and
adjustments.
The inputs to the CX-22 may be either dry or wet, (or both),
meaning that 3-terminal radio receivers may be connected
directly to the CX-22 without fear of malfunction.
The relays have adjustable delay-on-release times of
1 to 30 seconds. The delay between the two relays is
also adjustable from 1 to 30 seconds.
Washroom Door Controller
In this mode, complete control of a single occupant
barrier-free washroom is obtained. It allows the user
to lock and secure the door from the inside by
depressing a Push-to-Lock button. The exterior wall
switch is removed electronically from the circuit.
To exit the washroom, simply exit manually via the
lever-handle set (the Door Contact Switch resets the
relay), or, press the interior wall switch to unlock and
activate the door operator. The door remains
unlocked upon closure.
Another feature is the ability to use the CX-22 on
“Normally Secure” washrooms. In this mode, the
door is usually locked. To gain access, the user must
first swipe a card, or enter a code into the Access
System (ie - Keypad), which then signals the CX-22
to unlock and open the door. Once inside, the
occupant presses the Push-to-Lock button, which
removes the exterior wall switch from the circuit.
Exiting may be accomplished manually via the lever-handle
set (the Door Contact Switch resets the relay), or, by
pressing the interior switch to unlock and activate the
door operator. The door will re-lock upon closure.
NOTE: We highly recommend the use of a
regulated power supply when powering strikes
for barrier-free washroom applications where the
strike power may be maintained from a few
minutes to many hours. We offer a low-cost
board-only regulated power supply - CX-PS13
V2, which can be powered from a small 24VAC
transformer, (or the auxiliary power on the door
control) and will supply clean, filtered &
regulated 24VDC power for the strike.
Bi-Directional Door Sequencer
In this mode, the relay will sequence two Automatic
doors, in both directions.
Upon a switch closure from one side, a signal is sent
to the first door (relay 1), then after an adjustable
delay, the second door (relay 2) receives a signal.
When a switch closure is made from the opposite
side, the sequence is reversed – Relay 2 is activated,
then after the adjustable delay, relay 1 activates.
When used as a door sequencer the user can select
either momentary position for the inputs, or
maintained position. In the momentary position, even
a stuck switch input will allow the door to time out and
close, thereby providing security to the occupants.
The CX-22 will however, still operated normally if one
of the other inputs is activated. Essentially, it ignores
the faulty activation source, as all the inputs are
isolated. In the maintained position, a switch that is
held on will cause its respective relay (operator) to be
held on. So switch #1 would hold in relay #1, and
switch #2 would hold in relay #2.
If an emergency (or anti-entrapment) switch is
desired in the vestibule, then wire that switch directly
to one of the operator inputs. Usually the exterior
door is used in this case.
