mortise which prevents the heat transfer by cables and holes connecting
the inner and outer devices.
EPIC Security also and connects the inner and outer bodies with harness cables but makes no 32mm holes on the fire door, and prevents the heat transfer by installing no bracket. As a result, the product can be easily and conveniently installed without additional installation of brackets.
