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 variety 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. Mounting Base Selection Guide Base Model Number B401B B401BR B402B B404B Version UL/ULC UL/ULC UL/ULC UL/ULC Loop Type 2-wire* 2-wire* 4-wire 4-wire Current Limit Resistor No Yes Yes Yes Alarm Contact Type — — Form A&C Form A&C+A Supervisory B406B B401† B401R† UL/ULC/EN-54 UL/EN-54 EN-54 2-wire* 2-wire* 2-wire* No No Yes Form C — — 24VDC 12/24VDC†† 24VDC 12–100** 10–100** 10–62 Nominal Voltage 12/24VDC†† 24VDC 24VDC 120VAC Current Draw on Alarm (mA) 10–100** 10–62 14–39 75 mA AC Max *Functionality contingent on panel compatibility. **Must be limited by control panel.
