Loop isolation module

MI-DISO

The Morley-IAS loop isolator module is used on the Morley-IAS intelligent fire alarm control panels to protect the system against wire-to-wire short circuits on the analogue addressable loop wiring. The fault isolator modules should be placed between groups of sensors on the loop wiring to protect the loop if a short circuit fault occurs.
