Before installing
Please thoroughly read the System Sensor manual A05-
1003, Applications Guide for System Smoke Detectors, which
provides detailed information on detector spacing, place-
ment, zoning, wiring, and special applications. Copies of
this manual are available at no charge from System Sensor.
(For installation in Canada refer to CAN/ULC-S524, Stan-
dard for the Installation of Fire Alarm Systems, and CEC
Part 1, Sec. 32.)
NOTICE: This manual should be left with the owner/user
of this equipment.
NOTICE: Model 1451 is a direct replacement for Honeywell
model TC805C1000
IMPORTANT: This sensor must be tested and maintained
regularly following NFPA 72 requirements. This sensor
should be cleaned at least once a year.
General Description
Model 1451 dual chamber ionization detectors utilize state-
of-the-art, unipolar sensing chambers. These detectors are
designed to provide open area protection, and to be used
with compatible UL-listed control panels only. The capa-
bility of plugging these detectors into a variety of special
bases makes them more versatile than equivalent direct-
wired models.
Two LEDs on each detector light to provide a local 360°
visible alarm indication. Remote LED annunciator capabil-
ity is available as an optional accessory. These detectors
also have the latching alarm feature. The alarm can be
reset only by a momentary power interruption. For test-
ing, these detectors have an internal magnetically activated
reed switch.
Model 1451 has been approved for marine use in dry loca-
tions by Underwriters Laboratory, Inc. The detector is to be
used in dry interior locations only.

Spacing
Spacing of 30 ft. on a smooth ceiling as per NFPA 72E.
Where conditions or response requirements vary, other
spacing may apply.
Base Selection And Wiring Guide
Refer to the installation instructions for the plug-in detector
bases for wiring instructions. System Sensor has available a
variety of detector bases for this smoke detector, including
2-wire applications with and without relays and/or current
limiting resistors, 4-wire and 120VAC applications. (Note:
the 120VAC detector base is not available in Canada.)
All bases are provided with screw terminals for power,
ground, remote annunciator connections, and relay contact
connections, if applicable. The electrical ratings for each
detector-base combination are also included in the base in-
stallation instructions.
Installation
NOTE: All wiring must conform to applicable local codes,
ordinances, and regulations.
NOTE: Verify that all detector bases are installed, that the
initiating-device circuits have been tested, and that the wir-
ing is correct.
Remove power from initiating-device circuits before install-
ing detectors.
