Specifications
Description
Addressable microprocessor module (with short-circuit isolator) installed as an additional loop element.
This module has a relay with an external 30V power supply and a technical signal input for detecting whether a volt-free contact is open or closed. The module is protected by a 0.9A self-resetting fuse, and the relay output by a 0.5A fuse.
The module is powered via the loop connection, but requires a 30V auxiliary power supply to provide the energy needed by the devices controlled by the relay marked "R1". The relay is programmed with a single function (sounder, operations or cross-relay), along with its timing and the combination of sensors that activate it. The presence of voltage on the 30V auxiliary power supply line and at the relay output is also monitored. The voltage supplied by the relay output is 30V.
A 10kk? resistor is connected in series with the volt-free contact on the technical signal input. In the idle state, the contact must be open; in the event of a fault, it must be closed. The input (marked IN2) detects the closed contact as an ALARM condition.
The MYOA monitors each external line (relay output and technical signal input) using a 33kk? resistor on each, indicating an open-line or crossed-line condition.
The flashing transparent red LED indicates communication with the control panel. A steady red LED indicates an alarm state at its input, while the green LED indicates relay activation.
Supplied in rectangular modules made of heat-resistant ABS.
The MYOA module is certified to EN 54-18 by AENOR and bears the CE marking in accordance with the European Construction Products Regulation (EU) No. 305/2011.
