System Sensor’s 400 Series plug-in smoke detectors are designed to meet the
performance criteria designated by UL/ULC. The ion units have a sensing chamber
sealed from back pressure air flow, dirt, and insects. This chamber is protected
by a fine mesh screen which can be cleaned or replaced. Additional key features
include a recessed mounting option, interchangeable ion, thermal detectors, a vari-
ety of mounting bases, and a full line of optional accessories.
Ionization.
All 400 Series ionization smoke detectors include a specially designed dual
source, dual unipolar detector chamber design which will sense the presence of smoke
particles produced by fast combustion as well as slow smoldering fires. This chamber
exhibits increased stability, significantly reduces nuisance alarms, and provides better
performance at higher air velocities.
Thermal.
The 400 Series thermal rate-of-rise with fixed heat detector contains a
unique dual thermistor heat sensing circuit to provide maximum performance and
solid state reliability. The Model 5451 is designed to initiate an alarm at 135°F and
to respond to a temperature increase in excess of 15° per minute. This enables the
heat detector to communicate an alarm to the central control panel prior to reaching
the static set point for these high rates of rise, providing a timely response to both
rapid and slow temperature increases. This model should be used in applications
where rapid response is desired and where rapid temperature increases would only be
caused by a fire emergency.
