Hochiki ESP – Isolators

Product Code: Various

Addressable EN54 Various EEA
System  Approval Weight  Conformity

The Hochiki ESP Isolators are compatible with any of the ESP Sensors. The Base incorporates an amber LED to show when it is isolating a section of the loop, and if used under every analogue Sensor on the loop, none would be
lost if a single short circuit was to occur. 
F/CH/YBO and F/CH/YBN do not use an address and as such they are very simple to install.
