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
unit has the same specifications as the Model 2400, but in ad-
dition it features a built-in fixed temperature (135
o
F) thermal
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.
