Notifier Combustible Gas Monitor - Manual (Page 3)

Flexible Applications
E 3 Point integrates easily with your building’s analog or digital
infrastructure as a standalone unit or network addressable
device. Here are five installation examples to make E
3 Point
work for you.
E 3 Point Standalone Dual-Gas Sensor Operation
Economical application adds
option of a second (remote) sensor
for dual gas monitoring. Two
on-board relays can activate
ventilation or strobes.
E 3 Point/BACnet (MS-TP) Configuration
E 3 Point outputs directly to BACnet or other BAS. Alarms, strobes and
horns are activated through BAS with link to DCV/HVAC controls. This
system design supports new and retrofit installations for large buildings,
and can couple with a controller to effectively integrate wired and wireless
system components. A relay output is provided as an option for activating
ventilation directly (e.g. when fan is located in close proximity to detector).
E 3 Point/Modbus Configuration
Supports Modbus protocol to daisy-chain E 3 Point detectors, providing up
to 96 points of monitoring on a serial bus. Excellent option for controller-
based (VA301C) installations common in larger applications. A relay output
is provided as an option for activating ventilation directly (e.g. when fan is
located in close proximity to detector).
E 3 Point/Wired-Wireless Hybrid Configuration
E 3 Point offers a perfect solution for applications that require a
hybrid wireless/wired system. In this configuration, E 3 Point outputs signals
to a controller (301CW) that also accepts signals from a wireless gas
detector (301W). This scheme offers great flexibility and installation cost
savings for retrofit projects. It easily handles difficult installation challenges,
such as those posed by obstructions. A relay output is provided when it
is desirable to activate fan/ventilation directly (e.g. when fan is located in
close proximity to detector).
E 3 Point Standalone Single-Sensor Operation
A low-cost application for buildings with
minimal gas monitoring requirements typical
of a small facility. Offers easy installation,
commissioning and operaton. Two on-board
relays can activate fan or strobe.
