Section 1 - INTRODUCTION
The
EVC-PY-IS
is an attractively-styled, low profile photoelectric smoke
detector for use in conventional fire detection systems.
The
EVC-PY-IS
has a chemically etched, stainless steel insect screen therefore
reducing the ingress of insects and airborne contaminants.
EVC-PY-IS features:
* Optical detector, detecting visible particles of combustion
* Low profile, stylish appearance
* Supplied with protective dust cover (remove during commissioning)
* Non-polarised terminals
* Unauthorised head removal signal facility
* Low monitoring current
* OMNIVIEW™ 360° LED fire alarm indicator
* Remote indicator output* Compatible with STB-4-IS and
UB-4-IS bases
Section 2 - EVC-PY-IS
The smoke chamber of the
EVC-PY-IS
is constructed so that light cannot enter
from outside, but smoke can pass through the chamber slots. The EVC-PY-IS
utilizes the light scatter sensing principle. An alarm condition is verified before
an alarm is given.
The detector design provides strong immunity to air velocities, contamination
and RF interference.
The geometry of the smoke chamber and optics support assembly is designed
to give the best possible signal to noise ratio, resulting in excellent response
characteristics.
Section 3 - DETECTOR MODELS
The
EVC-PY-IS
photoelectric smoke detector is supplied, as standard, with
four terminals.
The
EVC-PY-IS
has the facility to activate a remote LED indicator or auxiliary
function, as standard.
The terminals on the
EVC-PY-IS
detector head are configured as follows:-
Terminal 2 = zone positive in/out
Terminal 1 = zone negative in
Terminal 6 = zone negative out
Terminal 5 = 2mA @ 24V d.c. switched output
