Programming / test key of the COMTX transmitter
On each transmitter a key said “programming/test key” is pre
-
sent and a led. The pressure of the same key during the normal
functioning (so not in programming) produces a signal that is sent
N.B.: If one COMTX transmitter is in alarm but it necessary to open
or close the automation in any case, it’s necessary to press and
keep pressed the programming / test button of the indicted COMTX
transmitter of the indicated and in the same time to move the auto-
mation.
By the dip switch Low Power present on the transmitter device it
is possible to limit the frequency with which the transmitter device
transmits its state of functioning (period of interrogation): but in
this case it will be necessary to keep in consideration the condition
of dangerous that can be created if the power supply (battery) is
taken off to the transmitter during the interval of time before the
successive transmission of its state and successively the sensible
By the dip switch 1 of the receiver it is possible to select if the devi-
ce test must be carried out with a high logic signal (so the test will
activate itself if between the terminals TEST1 and TESTC will be
present a tension from 10V dc to 24 Vdc) or with a low logic signal
(so the test will activate itself if between the terminals TEST1 and
TESTC will be present a tension of 0Vdc). In this case, the test will
be for the device memorized to the relay 1. The same is for TEST2
and TESTC for the device memorized to the relay 2.
During this test, the receiver sends a signal to all the associated
transmitter with the request of their state. If all the devices answer
to the receiver which close the contact of the relay and answers to
this signal with:
WARNING: If the batteries are completely flat, it will be neces-
sary to change them.
edge goes on alarm: in this case the receiver will signal the alarm
only after the period of interrogation.
With the dip 2 of the transmitter on OFF: energy saving deacti-
vated, check the state of the transmitter each second (low power
deactivated) With the dip 2 of the transmitter on ON: energy saving
activated, check state of transmitter each 15 seconds (low power
activated).
positively, the test is passed and the correspondent relay (which
was previously open) re – closes itself.
With the dip 1 of the receiver on OFF: device test with high logic si-
gnal 10 - 24 Vdc (position to use if you don’t want to make the test)
With the dip 1 of the receiver on ON : device test with low logic
signal 0Vcc
Note : in case you want to use the test of the device, place the dip
1 on OFF position.

MEANING
WHAT TO DO
1
Regular functioning, no mistake found.
-
2
One or more sensitive edge on alarm or interrupted 8K2 rib
Check the sensitive edges connected
3
One or more 8K2 safety sensitive edges under short circuit
Check the sensitive edges connected
4
Battery tension under the level of attention
Substitute the batteries of the indicted device
5
Battery tension under the minimum level.
Substitute the batteries of the indicted device
6
One or more associated devices disconnected
Check each associated device
