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.

1451A Same as above, Canadian model

5451 Fixed heat detector with rate-of-rise. Alarm point at 57.2°C (135°F). Must be mounted to one of the 400

Series Bases listed in Mounting Base Guide.

Accessories Description

RA400Z Remote annunciator for 2- or 4-wire systems, 3–32V. Use with ion and photo plug-in detectors.

Fits standard U.S. single gang electrical box.

B401BH Sounder base with B401. Requires an external 24 VDC power supply.

The MOD400R Field Sensitivity Test Module can be used with

any standard DC voltmeter or multimeter to check the sensitivity

range of System Sensor’s detectors (satisfies NFPA 72 require-

ment for sensitivity testing).

a simple installation solution where applications demand a

lower profile smoke detector and reduces the depth of any

400 Series plug-in detector by almost an inch. A special

metal mounting bracket secures the kit and the base to

the junction box and ceiling panel. (For use with B401 and

B401R bases only.)
