photoelectric / heat sensor
Section 1 - INTRODUCTION
The
EV-DPH
is an attractively-styled, low profile photoelectric / heat
sensor for use with Nittan 'evolution' protocol
control panels.
The
EV-DPH
has a chemically etched, stainless steel insect
screen therefore reducing the ingress of insects and
airborne contaminants.
EV-DPH 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
* A2R or CS Grade heat detectors
* EEPROM addressable (hand held programmer)
* Low profile, stylish appearance
* Supplied with protective dust cover,
(remove during commissioning)
* Low monitoring current
* OMNIVIEW™ 360º LED fire alarm indicator
* Remote indicator output
* 'Base Control' auxilary ouput
* Non-polarised terminals
* Compatible with UB-4-EV and STB-4SE-EV bases
Section 2 - SENSOR MODELS
The
EV-DPH
dual wave length photoelectric / heat 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-DPH
sensors. It is
important to use the correct base for each application. The available
base models are:
i) UB-4-EV base:
For standard use with EV-DPH series
photoelectric sensor.
ii) STB-4SE-EV base:
Similar to UB-4-EV but deeper.
