System Sensor’s ił™ Series photoelectric and photoelectric/ thermal smoke detectors represent a significant advancement in conventional detection, incorporating three key features: installation ease, intelligence, and instant inspection.

Installation ease. The ił Series redefines installation ease with its plug-in design. This allows an installer to pre-wire the bases included with the heads. The large wire-entry port and in-line terminals provide ample room for neatly routing the wiring inside the base. The base accommodates a variety of backbox mounting methods, as well as direct mounting with drywall anchors. To complete the installation, ił Series heads plug into the base with a simple Stop-Drop ’N Lock™ action.

Intelligence. ił Series detectors offer a number of intelligent features to simplify testing and maintenance. Drift compensation and smoothing algorithms, to minimize nuisance alarms, are standard in the ił Series. When connected to the 2W-MOD loop test/maintenance module, an SFP-2402/-2404 panel, SFP-5UD/10UD, or RP-2001/2002 two-wire ił detectors are capable of generating a remote maintenance signal when they need cleaning. This signal is indicated by LEDs located at the module and at the panel. To read the sensitivity of ił detectors, the SENS-RDR is a wireless device that displays sensitivity in terms of percent-per-foot obscuration.

Instant inspection. The ił Series provides wide-angle red and green LED indicators for instant inspection of detector condition. The LEDs indicate: normal standby, out-of-sensitivity, alarm, or freeze trouble conditions. The “EZ Walk” loop test feature is available on two-wire ił Series detectors when con- nected to the 2W-MOD loop test/maintenance module. The “EZ Walk” feature verifies the initiating loop wiring by providing LED status indication at each detector.

  • Plug-in detector line — mounting base included.
  • Large wire-entry port.
  • In-line terminals with SEMS screws.
  • Mounts to octagonal and single-gang backboxes, 4" (101.6mm) square backboxes, or directly to ceiling.
  • Stop-Drop ’N Lock attachment to base.
  • Removable detector cover and chamber for easy cleaning.
  • Built-in remote maintenance signaling.
  • Drift compensation and smoothing algorithms.
  • Simplified sensitivity measurement.
  • Wide-angle, dual-color LED indication.
  • Loop testing via “EZ Walk” feature.
  • Built-in test switch.

This ability to reject certain nuisance alarm triggers, such as theater smoke, supports the use of the detector in applications where mod- erate to heavy nuisance conditions exist that might cause single sensing detectors to trigger a false alarm.

The PTIR detector meets both UL 268 7th edition and UL 521 listing requirements and can indicate distinct smoke and heat alarms. This dual nature supports a local alarm setting for photoelectric detection and a general evacuation setting based on thermal detection. This can minimize work interruptions in multi-level buildings. Canadian models meet listing requirements of CAN/ULC S529 and CAN/ULC S530.

Architectural/Engineering Specifications

Smoke detector shall be a System Sensor ił Series model number ________, Listed to Underwriters Laboratories UL 268 Fire Protection Signaling Systems. The detector shall be a photoelectric type (models 2W-B, 4W-B) or a combination photoelectric/thermal (models 2WT-B, 4WT-B) with thermal sensor rated at 135°F (57.2°C). The detector shall include a mounting base for mounting to 3.5" (88.9 mm) and 4" (101.6 mm) octagonal, single-gang, and 4" (101.6 mm) square backboxes with a plaster ring, or directly 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 base and the head shall be a plug-in type. The detector shall have a nominal sensitivity of 2.5%/foot (0.762%/meter) as measured in the UL smoke box. The detector shall be capable of automatically adjusting its sensitivity by means of drift compensation and smoothing algorithms. The detector shall provide dual-color LED indication which blinks to indicate power-up, normal standby, out-of-sensitivity, alarm, and freeze trouble (models 2WT-B, 4WT-B) conditions. When used in conjunction with the 2W-MOD module, two-wire models shall include a maintenance signal to indicate the need for maintenance at the alarm control panel, and shall provide a loop testing capability to verify the circuit without testing each detector individually.
