7 INSTALLATION TIPS AND TRICKS
CABLING

Cabling – use 2-3 conductor cable, depending if BAS and/or VFD output is utilized.
Generally, 18 gauge conductors are used (not true in all cases). Shielded wires are
used to connect all gas sensors.

Route cabling in conduit to avoid damage to cabling.

Sensor cable sheath must be grounded at the monitor end only; the cable sheath at the
sensor must be clipped short and wrapped with electrical tape to avoid electrical contact
with any components in the housing.

Route cabling away from AC power cabling and any source of electro-magnetic
interference (EMI) or radio frequency interference (RFI) such as power transformers,
electric motors, etc.

EMT (Electrical Metal Tube) conduit also adds an added degree of electrical shielding
against EMI (Electro-Magnetic Interference) from devices such as RF (i.e. radio)
sources.

All cabling must enter the sensors and monitors from the bottom to ensure protection
against water damage due to water inside the conduit from condensation or leaks.

Ensure that there are no short or open circuits in the sensor cabling.

Verify that there is no AC or DC voltage present on the sensor cabling prior to
connecting the cabling to either the sensor or the monitor.
EQUIPMENT LOCATION

Mount all equipment away from any source of electro-magnetic interference (EMI) or
radio frequency interference (RFI) such as power transformers, electric motors, etc.

Mount sensors in accordance with the installation guidelines for the specific species of
gas to be detected; i.e. CO sensors should be mounted at breathing height etc.

Equipment must be positioned such that the chance of water damage is minimized; i.e.
away from fire suppression sprinkler heads, away from wet or damp locations where
there would be a risk of water damage.

Ensure a balanced layout of sensors to cover the intended area.

Ensure that sensors are not in close proximity to clean air sources.

Ensure proper procedures are followed If equipment is to be installed in a confined
space within a hazardous location.
POWER AND GROUNDING

All power and grounding connections to equipment must be made in accordance with
applicable electrical and building codes.

A separate, dedicated, noise free, 15 amp power circuit, with an appropriately labeled
circuit breaker.
