System Sensor 2251TMB EngSpec

Product Multi Criteria Acclimating Detectors and Engineering Specifications multi criteria acclimating detector shall be a System Sensor model number 2251TMB device shall be designed to monitor a space with a minimum of photoelectric and technologies in single sensing device The detector shall include the ability to adapt to its and choose appropriate sensing settings The detector shall allow a wide sensitivity with no less than 1 to 4 percent per foot obscuration device shall be capable of selecting appropriate sensitivity levels based on environment type as office manufacturing or kitchen and then have ability to automatically change setting as changes as when walls are moved or as occupancy changes The detector shall be of automatically adjusting its sensitivity by means of drift compensation and smoothing The device shall provide unique signals to indicate when 20 of the drift range is when 100 of drift range is used and when there is a chamber fault to indicate unit maintenance The device shall be able to indicate distinct smoke and heat alarms multi criteria detection device shall include the ability to combine the signals of thermal with the signal of a photoelectric sensor to react quickly in event of fire situation detectors shall provide address setting means on the detector head using rotary switches of the possibility of installation error systems that use binary jumpers or DIP switches to the detector address are not acceptable The detectors shall also store an internal identifying that the control panel shall use to identify the type of detector Systems that require a programmer to set the detector address including temporary connection at the panel are intensive and not acceptable Each detector occupies any one of at least 99 possible on the signaling line circuit SLC loop It responds to regular polls from the system reports its type and status detectors shall provide a test means whereby they will simulate an alarm condition and report condition to the control panel Such a test may be initiated at the detector itself by activating switch or initiated remotely on command from the control panel There are three test methods magnet smoke entry aerosol or direct heat method detectors shall provide two LEDs to provide 360 visibility The LEDs are placed into steady illumination by the control panel indicating that an alarm condition has been detected An connection shall also be provided in the base to connect an external remote alarm LED base and or relay base optional accessories The external remote alarm can be to other sounder or relay bases for activating all devices in a space via a single unit LEDs on the sensor are controlled by the panel to indicate sensor status Coded signals from the panel can cause the LEDs to blink latch on or latch off Refer to the control technical documentation for sensor LED status operation and expected delay to alarm detectors shall be low profile ceiling mount and shall be plug in mounted into a twist lock These detectors shall be constructed of off white UV resistant polymer and shall be from the mounting base to simplify installation service and maintenance Mounting wiring connections shall be made by means of SEMS screws The detector shall allow pre of the base and the head shall be a plug in type Mounting base shall be mounted on box which is at least 1.5 inches 3.81 cm deep Mounting base shall be available to to standard junction boxes Suitable boxes include 10.16 cm square box with and without plaster ring 10.16 cm octagonal box 2009 8.89 cm octagonal box box 268 Smoke Detectors for Fire Alarm Signaling Systems Agency Standards CAN ULC S529 Smoke Detectors for Fire Alarm Systems 3230 3250 Smoke Actuated Detectors for Automatic Fire Alarm Signaling 2009
