CX-29
Besam Switching Network &
Bi-Directional Door Sequencer
Installation Instructions
MADE IN CANADA PAGE 1 OF 8
Section 1__________________
General Description
The CX-29 is a special version of our CX-12
designed to work on doors with Besam Swingmaster
operators and equipped with Magnetic locks.
When set in mode 2 or 3, the relay will unlock the
door(s), then activate the Besam operator(s). The
locks will stay deactivated until the door position
switch tells the CX-29 that the doors have closed.
Then after a delay, the doors are relocked. An
optional connection to a fire alarm panel will unlock
the doors and disable the operators when a signal is
received. The signal can be Normally Open, or
Normally Closed.
SEE DIAGRAM 02
.
There are
4 Modes of operation:
1. Standard make/break relay mode
2. Besam Swingmaster with N.O. Fire alarm input
3. Besam Swingmaster with N.C. Fire alarm input
4. Bi-directional door sequencing.
In the standard
make/break relay
mode, even a
stuck switch input will allow the door to time out and
close, thereby providing security to occupants. The
CX-29 will however, still operate normally if one of
the other inputs is activated. Essentially, it ignores
the faulty activation source, as all inputs are isolated.
The inputs to the CX-29 may be either dry or wet
(powered), meaning that 3-terminal radio receivers
may be connected directly to the CX-29 without fear
of malfunction.
SEE DIAGRAM 01
.
Additionally, we provide a direct connection from an
apartment interphone panel. Only Relay #1 (strike)
will operate when a voltage is applied to this input. A
vestibule courtesy switch will be energized for the
time set by Pot. 1.
SEE DIAGRAM 03 a or b.
Select
Bi-directional Sequencer
mode when you
wish to sequence two doors in both directions using
just one relay. The CX-29 allows for either wet or dry
inputs for both directions.
SEE DIAGRAM 04.
IMPORTANT
: Do not apply power to the unit until
you have read the instructions fully and made the
required adjustments.

Installation
Mounting
The LED’s are visible through the wrap-around
sleeve, which also has cutouts for adjusting the
potentiometers, and setting the dip-switch. Once the
unit has been adjusted, it may be tucked up into the
operator header or affixed using the supplied Velcro.
Wiring
Wiring of this unit is dependant on the mode desired,
however
the
following
commonalities
apply.
Note:
Do not wire
Safety devices
to the CX-29.
If installed, wire your safety device directly to the
operator control box as per usual.
CAUTION:
Do not apply power to the unit until all
secondary wiring is complete, and dip-switches have
been set.
Both relay outputs are Form C and are rated at 3
amps maximum. Use relay # 1 for the strike or
electromagnet. Generally the
N.O. & COM.
terminals
(3 & 4) are used for a strike, and
COM & N.C.
(4 & 5)
are used with an electromagnet.
The door operator will be wired to relay #2
N.O. &
COM
terminals (6 & 7). In a door sequencing
application, door 1 is relay #1, and door 2 is relay #2.
The unit will operate on 12 or 24 volts, AC or DC.
Connect to Terminals 1 & 2, which are non-polarity
sensitive.
