Use and settings of the UltraCOM 4G relays
Connection for gate/latch (
NO - NC - Com
)
The panel has two relays for the connection of remote opening (
gate, latch, etc.
)
that can be controlled by call and SMS. The most common examples on the market
operate either “normally closed” (
NC
) or “normally open” (
NO
). This is why each
relay is composed of an NO output and an NC output. These are outputs with
adjustable opening time (
see next section
).
During communication with the panel, pressing key 1 will send the opening signal
to relay 1 of the panel. Pressing key 2 will send the opening signal to relay 2 of the
panel.
•
Normally closed (
NC
)
Please connect your gate/latch to terminals NC-1 (
or NC-2
) and COM-1 (
or COM-
2
) of the panel's terminal block. The panel
opens
relay 1 (
or relay 2
) continuously
or momentarily (
between 1 and 99 seconds, see next section
) when key 1 (
or 2
) is
pressed during a call or by sending an SMS (
see page 15
).
Note: this NC terminal is used to wire a breakaway latch.
•
Normally open (
NO
)
Please connect your gate/latch to terminals NO-1 (
or NO-2
) and COM-1 (
or COM-
2
) of the panel's terminal block. The panel
opens
relay 1 (
or relay 2
) continuously
or momentarily (
between 1 and 99 seconds, see next section
) when key 1 (
or 2
) is
pressed during a call or by sending an SMS (
see page 15
).
Note: this NO terminal is used to wire a release latch.
In DC power supply, if you need a transient 9-36V output (
for example, for triggering
a latch
), you can loop (
shunter
) the V+ via your COM-1 (
or COM-2
) relay.
Relay opening time
The UltraCOM 4G has 2 relays that can be opened remotely by call or SMS. You
can set the opening time of these relays between 1 and 99 seconds. You can also
choose not to have automatic closure of the relay (
then choose a duration of 00
).
By default, the duration of each relay is set to 5 seconds. To modify this duration,
you need to send the following command to the UltraCOM 4G:
1234#RT#n#XX
Variable data
Meanings
1234
Default password, to be adapted if the password is changed.
n
Relay number between 1 and 2.
XX
Duration in seconds between 00 and 99 (
00 for a relay without automatic
closure
).
