100-1W STANDARD DETECTOR
 | The detector is contained in an
outdoor NEMA 4 rated aluminum enclosure. It is equipped with a quick-release
mounting bracket for mounting onto the surface of a duct. The quick-release
mounting bracket allows for easy periodic cleaning of the lens
surface. Each
detector is equipped with an infrared LED located behind the protective lens.
This LED is used to test the opposing detector when more than one detector is
used in a duct. In this way each detector can test the sensitivity of the
opposing detector in actual operating conditions. |
100-2 VISIBLE LIGHT
 |
Each detector is equipped with a Visible Light Filter. If it is
found that the application requires the detector to be in conditions where
there is some ambient light present, the detector equipped with an optical
filter should be used. The sensitivity of the detector is the same but the spectral range
of the detector is limited to a narrower bandwidth. The filter used is a black
glass filter which only passes light wave lengths above 780nm. In other words,
all visible light is absorbed by the filter (hence the name black
glass). |
120-1 HIGH SENSITIVITY
| This highly sensitive detector is suitable for most applications
– even very large ducts. The flush surface inside the duct promotes self cleaning
and the small weather proof enclosure makes service a breeze.
The 120-1 features a
comprehensive through-the-lens sensitivity test, and the highest sensitivity
available. |
121-2, 121-3 HIGH TEMPERATURE,
HIGH PRESSURE
|
For high temperature applications, the detector must be kept remote
from the surface of the duct to protect the electronics. This is accomplished
by stainless steel clad fiber optic probes to “look” into the
duct. The 121
detectors feature a very tough and very smooth sapphire lens which promotes
self cleaning and resists abrasion and corrosion. The small size of the fiber optic probes
also makes them ideal for mounting to small ducts. The 121 detector is available with either 2
or 3 fiber optic probes. |
122-2X, 122-3X EXPLOSION PROOF
|
The 122-2X and 122-3X detectors are designed to meet the requirements of Class II
environments. Since cable entry must be via rigid conduit, flexible fiber optic
probes are used to facilitate cleaning of the lens.
The 122-2X has two fiber optic probes and the 122-3X has three.
|
220-1
| The 220-1 is similar to the 120-1 but is
designed to interface with fire alarm control panels, PLC’s, etc. The
220-1 requires 24 VDC and provides an open collector control for powering
various devices. The 220-1 offers a standard 4 wire interface with normally
open, dry contacts. Through the lens sensitivity is provided for pairs of detectors
giving a pass / fail response. |
221-2/3 HIGH TEMPERATURE
| The 221-2 and 221-3 are similar to
the 121-2 and 121-3 but are designed to interface with fire alarm control panels,
PLC’s, etc. The 221 requires 24 VDC and provides an open collector control
for powering various devices. The 221 offers a standard 4 wire interface with
normally open, dry contacts. The 221-2 has two fiber optic probes and the 221-3 has three.
|
222-2X/3X EXPLOSION PROOF
| The 222-2X and 222-3X are similar to
the 122-2X and 122-3X but are designed to interface with fire alarm control panels,
PLC’s, etc. The 222 requires 24 VDC and provides an open collector control
for powering various devices. The 222 offers a standard 4 wire interface with
normally open, dry contacts. The 222-2X has two fiber optic probes and the 222-3X has three.

4600
 | The ODTI
4600 Infra Red Ember Detector is an ultra sensitive optical sensor designed to
detect the radiant energy emitted by burning or glowing embers being
transmitted on conveyer belts. The detector is designed to detect a 1 sq. inch
ember at a distance of 3 feet traveling at up to 20 fps. The 4600 is sensitive only to the
radiation emitted by the formation of CO2 produced by a smoldering ember and is
insensitive to ambient light - even solar.

SharpEye 20/20SI
|
The patented triple IR circuit design scans for oscillating IR
radiation (1 to 10 Hz) in the spectral bands ranging from 4.0 to 5.0 microns.
This highly advanced detector uses programmed algorithms which check the ratio
and correlation of data received by the three sensors. Only detection of
radiation emissions matching the spectral fingerprint of fire will produce an
alarm, making the 20/20SI highly immune to false alarms.
