Thermal Rate-of-Rise

Product Overview

Low standby current

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.

Two visible LEDs “blink” in standby and

provide a 360° ﬁeld viewing angle

Wide variety of mounting bases with

built-in shorting spring

Detector head plugs easily into base

Built-in test switch

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.

Field sensitivity metering of detector to

meet the requirements of NFPA 72

Built-in tamper-resistant feature

SEMS screws for easy wiring

Optional recessed mounting

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.

Removable cover and insect screen for

ﬁeld cleaning
