GENERAL
The System Sensor
1400
ionization smoke detector re-
sponds quickly to both fast flaming and slow smoldering
fires as required by
UL 268. The unipolar dual chamber
sensor has the sensitivity needed to quickly detect smoke,
and the stability needed to avoid false alarms.
FEATURES
Detects both visible and invisible smoke.
Used with UL listed control panels.
Unipolar ionization sensing chamber:
a) Provides exceptional stability.
b) Factory preset 1.9% nominal sensitivity.
c) Stable operation in air velocities up to 1,200 feet-per-
minute (7.6 meters per second).
Removable cover for field cleaning.
Visible LED blinks in standby.
Sealed against dirt, insects and back pressure.
Three-year limited warranty.
8.5 - 35 VDC operating range.
Field metering of detector sensitivity.
Built-in test switch.
Low standby current.
Built-in tamper-resistant feature.
Direct surface or electrical box mounting.
Remote LED option.
Insect-resistant screening (maximum to 0.020"/0.508
mm openings).
SEMS screws for easy wiring.
APPLICATIONS
Use to contribute to life safety, fire protection, and property
conservation. Superior to photoelectric detectors in de-
tecting fast-flaming fires. Superior to bipolar detectors in
avoiding false alarms.
CONSTRUCTION AND OPERATION
The 1400 Series ionization smoke detectors contain a
unique dual source, dual unipolar chamber detection de-
sign which will sense the presence of smoke particles
produced by fast combustion as well as slow smoldering
fires. Additional key features include a blinking LED
standby status indicator, an easily visible alarm indica-
tion and provision for convenient field test and metering.
The back of the detector is sealed to block back pressure
air flow. The chamber is protected by a fine mesh (0.020"/
0.508 mm) screen to minimize problems with dust, dirt,
and insects. If cleaning is required, the cover is easily
removed (with a special tool), providing access to the
screen and chamber to perform a thorough cleaning.
INSTALLATION
Model 1400 detectors are intended for use with FireLite
UL listed control panels. Maximum number of detectors
per zone depends on capacity of panel (see FireLite De-
vice Compatibility Document #15384). Easy to install and
maintain, this detector is designed for direct surface
mounting (mounting bracket included), or mounting to a
4" octagonal or smaller box.* Easy-to-wire screw termi-
nals allow fast and simple field wiring of in, out, and re-
mote annunciator connections. The wiring diagram
(page
2)
shows the correct method for wiring Model 1400 detec-
tors.
To prevent wiring mistakes, observe polarities and make
certain that each conductor is identified. A copy of the
installation and maintenance instructions is packaged with
each detector. For further information, refer to NFPA 72
Standard on Automatic Fire Detectors, and to local Au-
thority Having Jurisdiction.
*NOTE:
For Canadian applications, always use a mounting elec-
trical box.
