This manual is available at www.systemsensor.com. (See link at bottom of page 4.) This manual shall be left with the owner/user of this equipment. This detector must be tested and maintained regularly following 72 requirements. At a minimum, cleaning should be performed annually. DESCRIPTION 2W-B and 2WT-B are 2-wire photoelectric smoke detectors; models and 4WT-B are 4-wire photoelectric smoke detectors. All models in- a state-of-the-art optical sensing chamber and an advanced micro- The microprocessor allows the detector to automatically adjust its back to the factory setting when it becomes more sensitive due to settling in its chamber. In order for this feature to work prop- the chamber must never be opened while power is applied to the smoke This includes cleaning, maintenance or screen replacement. Should become necessary, the screen/sensing chamber is field replaceable. Mod- 2WT-B and 4WT-B also feature a restorable, built-in, fixed temperature thermal detector and are also capable of sensing a freeze if the temperature is below 41 (5 i3 Series detectors are designed to provide open area protection. Two-wire must be used with compatible UL Listed panels only. The MOD2W manual is available on-line at www.systemsensor.com. used with an i3 Series compatible control panel or the i3 Series MOD2W (see installation manual I56-4001), the 2W-B and 2WT-B are capable generating a needed signal. The MOD2W can indicate a for cleaning, replacement, or a freeze condition (2WT-B only) at the panel or module. of the 2W-B, 2WT-B, 4W-B, and 4WT-B detectors is simplified by use of a mounting base that may be pre-wired to the system, allowing the to be easily installed or removed. The mounting base installation is simplified by the incorporation of features compatible with drywall LEDs on the detector provide a local visual indication of the detector status: 1.
