Section 1 - INTRODUCTION
The EV-DP is an attractively-styled, low profile
photoelectric smoke sensor for use with Nittan
'
evolution
' protocol control panels.
The EV-DP has a chemically etched, stainless steel
insect screen therefore reducing the ingress of insects
and airborne contaminants.
EV-DP features:
* Optical detector, using dual wavelength LEDs and
supporting a uniform response in any EN-54 Test Fire
* Resistance to false alarms caused by steam
* Soft addressing
* Low profile, stylish appearance
* Supplied with protective dust cover,
(remove during commissioning)
* Low monitoring current
* Patented OMNIVIEW

o
LED fire alarm indicator
* Remote indicator output
* 'Base Control' auxilary ouput
* Non-polarised terminals
* Compatible with STB-4-EV and STB-4SE-EV bases
Section 2 - SENSOR MODELS
The EV-DP dual wavelenth photoelectric smoke sensor
has two terminals for connection onto the two wire loop.
The remaining terminals provide a switched current sink
function which operates when the detector goes into
alarm condition, suitable for the operation of an auxiliary
function such as a remote indicator. Terminal 3 (RIL) is
limited to 3mA. Terminal 2 (Base Control) is not current
limited.
Section 3 - BASE MODELS
A variety of bases are available for use with the EV-DP
sensors. It is important to use the correct base for each
application. The available base models are:
i) STB-4-EV base: For standard use with EV-DP series
photoelectric sensor when auxiliary output not used.
ii) STB-4SE-EV base: Similar to STB-4-EV base, except
deeper.
