C o n v e n t i o n a l D e t e c t i o n 400 Series™ Direct-Wire Ionization Smoke Detector Models Available 1400, 2-Wire 1412B, 4-Wire 1424, 4-Wire 1400 2-Wire Ionization Smoke Detector Accessories A77-716B RA400Z MOD400R CRT400 RS14 End of line relay module, 12/24 VDC Remote LED annunciator Sensitivity test module Ionization cover removal tool Replacement screen Product Overview 12 or 24 volt operation Removable cover and insect screen for easy cleaning Visible LED blinks in standby, latches on in alarm All 400 Series ionization smoke detectors include a unique dual source, dual unipolar chamber detection 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. Dual unipolar chamber design The 400 Series meets the performance criteria required by UL/ULC. Additional key features include an LED which blinks in standby and latches on to indicate an alarm. Detectors feature convenient field testing and sensitivity metering. The model 1400 includes remote LED annunciator capabilities using the RA400Z. Field sensitivity metering of detector to meet NFPA 72 requirements Engineering Specifications Twist-on mounting bracket with tamper option SEMS screws for easy wiring 3-year warranty Sealed against dirt, insects, and back pressure S911 427-91-E VOL II CS308 OQ7-A3.AY 7271-1209:102 Smoke detector shall be an ionization type (model 1400, 1412B, or 1424) as manufactured by System Sensor. Wiring connections shall be made by means of SEMS screws. Detector will have a visible LED which will blink in standby and latch on in alarm. The detector shall have a sensitivity of 1.9 ± 0.6%/ft. as measured in the UL smoke box. The detector screen and cover should be easily removable for cleaning. It shall be possible to perform a sensitivity and functional test on the detector without the need of generating smoke. The detector shall have a mounting bracket that allows for mounting to a 3 1/2 ″ or 4″ octagon box or 4″ square electrical box.
