FCI 2400 Series Instruction manual

DESCRIPTION
The System Sensor 2400 Series photoelectronic smoke de-
tectors are specifically designed to meet the performance re-
quirements of fire detection/alarm systems. These detectors
use state-of-the-art optical sensing chambers. The detectors
are designed to provide open area detection and are compati-
ble with FCI fire alarm control panels. The detectors’opera-
tion and sensitivity can be tested in place. The Model 2400T

detection unit.
Each detector has an LED which flashes every ten seconds
indicating that power is being applied to the detector. The
LED lights steadily when the detector is in alarm. A remote
LED annunciator is available as an optional accessory.
The 2400 and 2400T detectors include a tamper-resistant
feature that, when used, prevents removal of the detector
without the use of a tool.
Sensitivity testing is performed either by inserting a tool
into the recessed test switch opening or inserting a calibrated
test card according to the test procedures.
Field metering of detector sensitivity may be performed
with the aid of a voltmeter and test kit MOD 400R.

NOTE: The number of two-wire smoke detectors
which can be accommodated per zone varies with dif-
ferentcontrol panels. Consult thecontrolpanel instruc-
tion manual to determine the capacity.
Refer to NFPA 72, Chapter 5-3 “Smoke Sensing Fire
Detectors”, for spacing, location of detectors and other
guidelines.
TESTING
Detectors may be tested locally in the following
ways:
·A. Insert a tool into the test opening in the unit.
For the complete procedure, refer to the Instal-
lation and Maintenance Instructions furnished
with each detector.
·B. A test card with one end marked “ALARM”
and the other end marked “NO ALARM” is
furnished with each unit. For the complete
procedure, refer to the Installation and
Maintenance Instructions furnished with each
detector.
·C. Field metering of detector sensitivity may be
performed with the aid of a voltmeter and test
kit MOD 400R. For the complete procedure,
refer to the Installation and Maintenance
Instructions furnished with each detector.
MAINTENANCE
Cleaning programs should be adapted to the individ-
ual environment. in conformance with NFPA Standard
72. We recommend, at the least, an annual cleaning of
theunit.Thedetectorscreenand coverassembly canbe
removed, revealing the sensing chamber. A vacuum
cleaner can be used to remove dust from the screen,
cover and sensing chamber. For the complete proce-
dure, refer to the Installation and Maintenance Instruc-
tions furnished with each detector.

WARNING: To prevent detector contamination
during construction, smoke detectors must be
protected from dust and contamination until area
is clean and dust free.See NFPA 72-5-3.7.1.3
