1.5.3.2- Master relays module (MDA1Y)
Microprocessed analogue and addressable devices (with short-circuit
isolator) installed as another element inside the loop.
The Modules take the power supply from the loop, but they require an
auxiliary 30V supply to give the necessary energy to the devices controled by
the relays. They monitor the presence of Voltage in the auxiliary supply line of
30V and in the output of the monitored relays. The Module is protected by 0.9
A resettable fuse and each monitored output by 0,5 A. The flashing of the
transparent red LED indicates communication with the Lyon system.
Illumination of the green LED indicates the actuation of a relay.
The device is placed in a rectangular, heat-resistant ABS box.
This is a module with two relay outputs of simultaneous activation
(with a single function), not only in its type of application (sounder, switches
or crossed relay), but also in their timing and in the combination of sensors
that activate them. The R1 output relay is monitored with a line termination
resistance of 33K
Ω
, indicating the state of opened line or crossed line. The R2
output relay acts as a dry contact NO and NC, not monitored, which typical
application is the energising of the electromagnets of fire-resistant doors.
Considering the consumption produced across the system, it is recommended
installation of an External Power Supply when connecting more than 10 electromagnets altogether per
detection system.
The
MDA1Y
is conformant with EN 54-18 with the conformity mark awarded by AENOR.
Connection will be made according to figure 4.
Note: To determine the number of MDA1Y it can be installed, consult the devices limit per
control panel table (Chapter 1.5)
1.5.3.3- Master relay module (MDA2Y)
Microprocessed analogue and addressable devices (with short-circuit
isolator) installed as another element inside the loop.
The Modules take the power supply from the loop, but they require
an auxiliary 30V supply to give the necessary energy to the devices controled
by the relays. They monitor the presence of Voltage in the auxiliary supply
line of 30V and in the output of the monitored relays. The Module is
protected by 0.9 A resettable fuse and each monitored output by 0,5 A. The
flashing of the transparent red LED indicates communication with the Lyon
system. Illumination of the green LED indicates the actuation of a relay.
The device is placed in a rectangular, heat-resistant ABS box.
It is a module with two relay outputs of independent activation (two
functions), not only in their type of application (sounder, switches or crossed
relay), but also in their timing and in the combination of sensors that activate
them. In the standby state, the MDA2Y monitors both external line by means
of a 33 K
Ω
resistance, indicating the state of open line or crossed line.
The
MDA2Y
is conformant with EN 54-18 with the conformity
mark awarded by AENOR.
Connection will be made according to figure 5.
Note: To determine the number of MDA2Y it can be installed, consult the devices limit per
control panel table (Chapter 1.5)
