1.5.4.2- Technical signals module (MSTAY)
Microprocessed addressable devices (with short-circuit isolator) installed as
one more element in the loop.
It has two inputs to distinguish between the open or close state of a dry contact
connected in series with a 10 K
resistor. In quiescent condition, the contact
has to be open, and in anomaly condition, the contact has to be closed. In the
first input (marked with IN1), the closed contact is detected as an ALARM
condition. In the second input (marked with IN2), the closed contact is
detected as FAULT Warning condition. It is possible to associate both inputs
having an alarm and fault conditions information.
In the quiescent condition, the device monitors the electrical connection
through a 33 K
resistor, which allows indication of open or closed electrical
connection status.
It is typically used to signal the status of other detection systems that may
exist, as for example, connection of flow sensors in the case of sprinkler
installations, end of travel in the case of fire-resistant doors, elevators, level
of deposits, etc.
The flashing of the transparent red LED indicates communication with the
Control Panel, and if it remains lit, it indicates an alarm status.
The illumination of the green LED indicates activation of one or both inputs.
This device has an output for connection to a remote action indicator, which is activated when in alarm status.
This element is electrical fed through the loop connection.
The
MSTAY
complies with EN 54-18 with the conformity mark awarded by AENOR.
Note: To determine the number of MSTAY it can be installed, consult the devices limit per control panel
