Master relay and technical signals module (MYOA)
Microprocessed addressable devices (with short-circuit isolator) installed as one
more element in the loop.
This module has one relay output fed by external 30 V and one technical signal
input to distinguish the open or closed state of a dry contact. The Module is
protected by 0.9 A resettable fuse and the relay by 0,5 A.
It is required auxiliary 30 V for feeding the equipments connected to the relay
output. The relay is configured with only one function (sounder, switched or
crossed relay), but also in its timing and in the combination of sensors that
activate it. The module monitors the presence of Voltage in the auxiliary supply
line of 30V and in the output of the monitored relay. The volatge ouput of the
realy is 30 V.
The technical signal input has a 10 K
resistor connected in series with the dry
contact. In quiescent condition, the contact has to be open, and in anomaly
condition, the contact has to be closed. In the input (marked with IN2), the
closed contact is detected as ALARM condition.
The
MYOA
supervises each external line (relay ouput and technical signal
input) through a 33 K
each one, which allows indication of open or closed
electrical connection status.
The flashing of the transparent red LED indicates communication with the Control Panel. The
illuminated green LED indicates the actuation of the relay an alarm status. Illumination of the green
LED indicates activation of the relay or closed dry contact. This module is electrical fed through the
loop connection.
The Realy and Technical signal Module is placed in a rectangular, heat-resistant ABS box.
The
MYOA
complies with EN 54-18 with the conformity mark awarded by AENOR.
There is a version with
MYOAF
reference that is identical to MYOA, except the closed contact is
detected as a fault.
Note: To determine the number of MYOA devices that can be installed in a loop refer to the
devices limit per control panel table (Chapter 1.5)
