CAUTION: These air duct detectors are designed for detection and con-
trol of products of combustion in a duct system. They are not
to be used for open area protection.
OPERATION
When the AD-3I/3ILP (AD-3I or AD-3ILP) is operating, a sample of air is
drawn from the duct and passed through the sampling chamber at low ve-
locity by means of the inlet sampling tube. The air sample passes through
the smoke detector mounted in the duct housing and is exhausted back
into the duct through the outlet sampling tube.
Alarm Indication
The System 3, System SXL-EX, System SXL, System XL3, MXL/MXL-IQ
Control Panel, and System PXL all have LEDs for alarm indication that are
used with the AD-3I/3ILP.
Alarm Condition
When used with the CP-2ER, MXL/MXL-IQ Control Panel, System PXL,
System SXL-EX, System SXL, System 3, or System XL3, the Model AD-3I/
3ILP operates directly from the control panel. An alarm condition on any of
these systems is indicated by visual and audible system devices. On XL3
Systems the alarm is also indicated on the DAX module and any optional
printers used. On MXL Systems the alarm is indicated on the Control Panel
display and on the optional printer. See system manuals for further infor-
mation.
After a fire is extinguished, and all products of combustion are cleared from
the duct system, each system can be reset at its respective control panel,
or remote annunciator, if available.
Trouble Condition
A trouble condition from an AD-3I/3ILP is indicated by visual and audible
devices on the control panel in the CP-2ER, System 3, System SXL-EX,
System SXL, System XL3, MXL/MXL-IQ Control Panel, or System PXL,
depending on the type of system in which it occurs. On System XL3 and
MXL/MXL-IQ Control Panels it also may be indicated by an optional printer.
