tested for Life Safety Applications and are not to be used in Life Safety Applications
in jurisdictions that require this certification.
• Only qualified trade installers should install, program, maintain and test system
incorporated therein. Installer is responsible for compliance of all applicable codes.
• Read, understand, and follow instructions thoroughly.
• The unit and associated systems require routine test and maintenance as
prescribed in the TG Series User's Manual section 'Periodic Test and Maintenance'
• Do not install in hazardous or classified locations.
• De-energize power supply prior to installation.
• Gas sensors should not be used as a substitute for proper installation, use, or
maintenance of gas emitting equipment.
• This device is designed to detect conditions that could result in acute effects of
gas exposure. It will not fully safeguard individuals with specific medical conditions.
If in doubt, consult a medical practitioner.
• Conduit is prone to condensation if it passes from one temperature zone to
another, such as from indoors to outdoors or from one part of a building to another.
This condensation may actually drip into the sensor if mounted below, causing
damage and/or poor readings.
In order to prevent condensation and water egress, seal both the top and
bottom of the conduit with a suitable expanding foam product (such as Polywater
Zipseal
TM
Alternatively, fiberglass insulation may be inserted in the conduit between the
cold and warm sections using a rigid wire or other method if both ends cannot be
sealed. Sealing is the preferred method.
• Conduit air flow entering sensor may prevent sensor from reading ambient
air properly, resulting in under measurement of gases. Plug sensor conduit in all
installations with a foam plug or seal as noted above in order to prevent airflow
from the conduit.
