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.
The device is supplied in a rectangular, heat-resistant ABS box, to be mounted on surface or on DIN rail.
The module is certified according to EN 54-18 Standard, and CE mark according to the European Regulation of Construction Products (UE) N° 2024/3110.

Sirens SIRAY/SIRAYL/SIRAY+BSLC
Sirens SIRAY/SIRAYL/SIRAY+BSLC
The SIRAY / SIRAYL / SIRAY+BSLC references consist of the following elements:
- SIRAY = Siren + SIRAYC Circuit
- SIRAYL = Siren with light + SIRAYC Circuit
- SIRAY+BSLC = Siren + SIRAYC Circuit + Siren Base with light
The SIRAYC circuit is a microprocessed, addressable digital module (with short-circuit isolator) that is installed as a loop element. The siren is made of heat-resistant ABS in red color.
It is a module with a single programming function in terms of timing and combination of sensors that activate it. This siren is configured as a relay acting as a siren.
Key features
The SIRAYL and SIRAY+BSLC variants additionally emit light signals, whereby SIRAY+BSLC additionally does so in accordance with its EN 54-23 certification (visual alarm device). The fact that these sirens specifically emit light does not affect the programming of the control panel. For this reason, these devices are programmed in the control panel as if they were the SIRAY reference.
The standard siren sound configuration is shown in Figure 8A according to EN 54-3 (acoustic device). The same figure shows the standard configuration of the light signal at the base of the SIRAY+BSLC siren in accordance with EN 54-23 (visual alarm device).
It is possible to change the selection of the tone and the light signal, but this operation affects the power consumption of the siren, and therefore the power consumption of the device. Figure 8B shows an equivalence table for the tone (standard 95 dB-1m and maximum loudness 105 dB-1m) and visual signal (W-2.4-2.3/7.5) selections. Precise calculation can be performed with the loop element capacity calculation software.
The internal wiring and positions of other microswitches must not be modified from those selected by default by the manufacturer.

- Standby consumption: 1 mA
- Consumption in alarm: 5-50 mA
- Circuit isolator: Yes
