Temperature Interlock

General Description

Description
The temperature interlock is designed to automatically
start kitchen hood exhaust fans and keep them
running while heat is being generated from the cooking
appliances. Hood systems should always be manually
started before equipment is turned on. If the operator
fails to turn the fans on, the interlock will turn the fans
on once enough heat is detected. The package consists
of a time delay relay, adjustable thermostat, junction
box, and a UL Listed, liquid-tight fitting. The relay can
be contained in a stand alone box or can be added to a
pre-engineered fan control center.
Purpose
To meet IMC, an interlock between exhaust fans and
cooking equipment must be present for all Type I hood
systems. This product will utilize a thermostat in the
exhaust duct collar or in the capture area of the hood
to detect heat generated from cooking operations and
automatically activate the exhaust fans if not already
turned on.
Product Application
The temperature interlock can be used with Type I and
Type II hoods. It is not to be used in conjunction with
exhaust fire dampers. Accurex recommends using one
interlock per hood system (activates all fans linked to
systems simultaneously).
Performance Goals
To meet IMC, the fans need to activate not more than
15 minutes after the first appliance served by that hood
has been turned on. Ambient kitchen temperatures are
not the same in all commercial kitchens. Therefore, set
point adjustments may be necessary on the thermostat
to make sure the system meets this 15 minute
requirement.
