what is the operation of Control Module(CM),MONITOR
Module(MM), MONITOR Module DUAL (MM2),Signal
Module(SM),Isolator Module(IM), please some one reply me..
the operation and application of these in FIRE ALARM SYSTEMS...
Answer Posted / asif.k64@hotmail.com
Modules work as a mediator between the fire alarm panels and
output devices like, smoke detector or MCP(manual call
point) actuators etc.
Control Module(CM)# Device Interface module
This Is an interface Module for automatic Switching or
Programmed outputs.
MONITOR Module(MM)# monitor module is an interface between a
control panel and normally open contact devices
MONITOR Module DUAL (MM2)# It is used for two wire
addressable devices, it can also monitor No contacts and
supervisory devices.
Signal Module(SM)#Signal modules (SM) to connect sensors and
actuators (Output devices) are the interfaces of the system
to the process. Digital signal modules acquire the binary
control signals to and from the process level.
Isolator Module(IM)# To protect the system against short
circuits, should be placed between each device on the
SLC (Signaling Line Circuit) loop to isolate a short-circuit
problem

What is the need of earthing transformer for delta side of a transformer. (Think of a line section between a star/delta transformer at a grid substation and delta/star transformer at a village. An earthing transformer is there at the delta side of the star/delta transformer at grid substation). As there are no ground reference there will not be fault current if a one phase is grounded. Further L-L phase will be sensed by the primary side of star/delta transformer as a L-G fault. So why an earthing transformer is required at delta side
