Remote alarm contacts
All MATOS Aria Medical Pharmacy Refrigerators include remote alarm contacts and these terminal
contacts enable the user to connect to a remote control station; these contacts can be found on the rear
of the cabinet.
WARNING
: These contacts must only be accessed by a competent electrician.
In order to use these contacts the following must be carried out:
1.
The refrigerator MUST be disconnected from the power supply before removing the terminal
cover.
2.
Unscrew the cover (figure 1) on the right hand side of the rear of the cabinet to expose the
connectors (figure 2).

3.
Use the right hand outer positions that correspond to the left hand cable positions for your
connections using 0.75mm cable stripped to 0.6mm.
4.
Depress the larger slot above the cable entrance on the right hand side with a small electrical
screwdriver. This allows the cable to be inserted into the slot directly below.
In the event of a door open alarm, high or low temperature alarm or power failure a remote relay will
switch within the controller to make an electrical circuit.
Please note that the contacts supplied are voltage free. A voltage of between 12V DC and 230V AC can
be connected at the contacts. The maximum load must not exceed 2A. The minimum power rating is
500mA / 12V AC.
In a normal condition (i.e. no alarm) the relay OPENS the contact for the remote alarm facility.
In an alarm condition the relay CLOSES the contact for the remote alarm facility.
