Relay and technical signal module MYOA-MYOAF
Relay and technical signal module MYOA-MYOAF
Microprocessed and addressable module (with short-circuit isolator) to be installed as a loop element.
Key features
This module has a relay with external 30V power supply and a technical signal input to discern the open or closed state of a dry contact. The module is protected by a 0.9A self-rearming fuse and the relay output is protected by 0.5A.
The module is powered by the loop connection, but requires a 30V auxiliary power supply to provide the necessary power to the devices governed by the relay marked “R1”. The relay is programmed with a single function (siren, maneuvers or crossed relay) as well as in its timing and combination of sensors that activate them. Likewise, the presence of voltage on the 30V auxiliary power supply line and also on the relay output is monitored. The voltage supplied by the relay output is 30V.
The technical signal input has a 10kΩ resistor connected in series with the dry contact. The contact must be open in the idle state and closed in the event of a fault. At the input (marked as IN2) it detects the closed contact with ALARM category.
There is also the MYOAF version, whose operation is identical to the MYOA, except that the closed contact is detected as a FAULT.
The MYOA monitors each external line (relay output and technical signal input) with a 33kΩ resistor on each, indicating open line or crossed line status.
The blinking of the transparent red LED indicates communication with the control panel. The permanent lighting of the red LED indicates the alarm status at its input, while the lighting of the green LED indicates the tripping of the relay.
It is supplied in rectangular modules made of heat-resistant ABS.
The MYOA module is certified according to EN 54-18 by AENOR, and CE marked according to the European Construction Products Regulation (EU) No. 305/2011.

These inputs can be configured by means of a microswitch as follows:
- Supervised (pin 1 μswitch ON); in idle state it supervises the external line by means of a 33KΩ resistor, indicating open line or crossed line status. Connecting a 10kΩ resistor in parallel will activate the corresponding input.
- Active by closed contact (pin 1 μswitch to OFF and pin 3 μswitch to OFF); the input at rest must be with open contacts, in case of event the input contacts must be crossed. This will be the factory setting.
- Active by open contact (pin 1 μswitch to OFF and pin 3 μswitch to ON); the idle input must be with the contacts crossed, in case of an event the contacts must be opened.
Using pin 2 of the configuration μswitch, select the type of event that the module will send to the control panel; ON Fault and OFF Alarm.
The configuration of the inputs is common to all of them.
The blinking of the transparent red LED indicates communication with the control panel, and if it remains on steady it indicates the activation of one or more inputs. This module has an output for the activation of a remote pilot, which is activated when it is in alarm status. The Technical Signals Module is powered by the connection to the loop.
