 INTRODUCTION 

1.1 

General description

 

The 

EVCA-P

 is an attractively-styled, low profile photoelectric smoke detector for use in conventional fire detection 

systems. This detector is also for use in analog fire alarm systems, the Nittan control panel NFU-7000 series, when the 

detector is connected to the analog addressable module EVA-ZMU-SCI Zone Module.
