System Sensor i3 Series Photoelectric Smoke Detectors

Photoelectric Detectors Sensor i3 series smoke detectors represent advancement in conventional detection i3 family is founded on three principles installation intelligence and instant inspection detector line mounting base included wire entry port terminals with SEMS screws to octagonal and single gang back boxes 4 square back or direct to ceiling Lock attachment to base detector cover and chamber remote maintenance signaling compensation and smoothing algorithms sensitivity measurement dual color LED indication testing via EZ Walk feature test switch Listings ease The i3 line redefines installation ease with its design This allows an installer to pre wire bases included heads The large wire entry port and in line terminals provide room for neatly routing the wiring inside the base The base a variety of back box mounting methods as well as mounting with drywall anchors To complete the installation i3 plug into the base with a simple Stop Drop Lock action i3 detectors offer a number of intelligent features simplify testing and maintenance Drift compensation and algorithms are standard with the i3 line to minimize alarms 2 wire i3 detectors can generate a remote LED maintenance signal when connected to the 2W MOD2 test maintenance module or a panel equipped with the i3 The SENS RDR a wireless device displays the sensitivityof i3 in terms of percent per foot obscuration inspection The i3 series provides wide angle red and LED indicators for instant inspection of the detector normal standby out of sensitivity alarm or freeze trouble connected to the 2W MOD2 loop test maintenance module a panel with the i3 protocol the EZ Walk loop test feature is on 2 wire i3 detectors This feature verifies the initiating loop by providing LED status indication at each detector Smoke Detector Specifications Specifications detector shall be a System Sensor i3 or direct mount to the ceiling using drywall anchors Wiring connections shall be made by means of SEMS screws The detector shall allow pre wiring of the and the head shall be a plug in type The detector shall have a nominal sensitivity of 2.5 percent per foot nominal as measured in the UL smoke box The shall be capable of automatically adjusting its sensitivity by means of drift compensation and smoothing algorithms The detector shall provide dual LED indication that blinks to indicate power up normal standby out of sensitivity alarm and freeze trouble Model 2WT B 4WT B conditions When used conjunction with the 2W MOD2 module 2 wire models shall include a maintenance signal to indicate the need for maintenance at the alarm control panel shall provide a loop testing capability to verify the circuit without testing each detector individually Specifications Voltage Ripple Voltage Current Alarm Current Standby Current Contact Ratings Specifications including base Temperature Range Humidity Range Sensor Trouble Terminals 12 24 V non polarized 8.5 V 35 V peak to peak of applied voltage 50 maximum average 4 wire 50 maximum average 130 mA limited by control panel 4 wire 20 mA 12 V 23 mA 24 V 100 4 wire n a inches 127 mm diameter 2.0 inches 51 mm height oz 178 g to 95 RH non condensing nominal to 22 AWG octagonal back box back box square back box with a plaster ring mount to ceiling Modes Mode up standby of sensitivity LED every 10 seconds every 5 seconds LED every 10 seconds every 5 seconds every 10 seconds Sequence for LED Indication LED status indication seconds Information Current mA max limited by control panel mA max limited by control panel mA 12 V 23 mA 24 V mA 12 V 23 mA 24 V loop test maintenance module reader replacement tool adapter bracket 6.6 inch 16.76 cm diameter System Sensor specifications subject to change without notice Visit systemsensor com for product information including the latest version of this data sheet
