up to 3000 FPM.
The ionization type detector shall utilize a standard base so that it may
readily be interchanged, without any modifications, with photoelectric or
thermal type detectors. The detector head shall house an alarm LED that
pulsates while the detector is in the normal standby condition and lights
steadily upon sensing an alarm condition. The detector shall be equipped to
provide a remote annunciator which will duplicate LED indication. The
detector head shall be equipped with a means of securing the head to the
base in such a fashion that the head may not readily be tampered with or
removed.
The products of combustion detectors - photoelectric type, shall be Fike.
The detector shall utilize solid state circuitry, a pulsed, infrared LED light
source, and a silicon photo diode receiving element. The receiving element
will normally not sense any light from the LED source. When smoke
particles enter the sensing chamber, the light source shall be reflected to the
sensing element. Comparative circuitry shall be incorporated so as to
discriminate between a valid "fire" signal and an intermittent "non-fire"
source. The entrance to the sensing chamber shall be surrounded by a fine
stainless steel mesh so as to prevent ready entry by insects, lint or dust. Unit
shall be dew proof and uninfluenced by high air velocity. The photoelectric
type detector shall utilize a standard base so that it may readily be
interchanged, without any modifications, with ionization or thermal type
detectors. The detector head shall house an alarm LED that pulsates while
the detector is in the normal standby condition and lights steadily upon
sensing an alarm condition. The detector shall be equipped to provide a
remote annunciator which will duplicate LED indication. The detector head
shall be equipped with a means of securing the head to the base in such a
fashion that the head may not readily be tampered with or removed.
The detector head shall be removable from its base for cleaning, service, or
replacement. The detector shall be capable of having its calibration checked
or adjusted in the field via the standard detector sensitivity monitor. This
same monitor shall be capable of checking ionization and photoelectric type
detectors. A detector may have sensitivity tested either in place as it is
exposed to the environment or in a calibrated smoke chamber to give a
reading of sensitivity which can be referenced against other like detectors
under known conditions. The detectors shall be FM approved, ULC listed
and UL listed to UL Standard 268.
