System Sensor Select Series Photo Thermal Eng Spec

Photoelectric Smoke Detector with Thermal and Engineering Specifications intelligent photoelectric smoke detector with thermal shall be a System Sensor model number 2351TB 2351TB IV The detector shall be an addressable intelligent photoelectric smoke detector and a fixed sensor in a single sensing device Detectors shall connect with two wires to the fire alarm control signaling line circuit SLC The detectors shall use the photoelectric light scattering principal to smoke density and shall on command from the control panel send data to the panel representing analog level of smoke density The fixed thermal sensors shall alarm at a fixed temperature of 135 The device shall be able to indicate distinct smoke and heat alarms The detectors shall provide means on the detector head using rotary switches Because of the possibility of installation systems that use binary jumpers or DIP switches to set the detector address are not acceptable detectors shall also store an internal identifying code that the control panel shall use to identify the type detector Systems that require a special programmer to set the detector address including temporary at the panel are labor intensive and not acceptable Each detector occupies any one of at least possible addresses on the SLC loop It responds to regular polls from the system and reports its type and detector can have its sensitivity tested required per NFPA 72 Chapter 7 on Inspection Testing and when installed connected to a compatible addressable fire alarm control panel The detectors provide a test means whereby they will simulate an alarm condition and report that condition to the panel Such a test may be initiated at the detector itself by activating a switch or initiated remotely command from the control panel There are three test methods functional magnet smoke entry aerosol direct heat method detectors shall provide two LEDs to provide 360 visibility The LEDs are placed into steady red by the control panel indicating that an alarm condition has been detected An output connection also be provided in the base to connect an external remote alarm LED sounder base and or relay optional accessories The external remote alarm can be interconnected to other sounder or relay for activating all devices in a space via a single alarming unit LEDs on the sensor are controlled by the panel to indicate sensor status Coded signals transmitted the panel can cause the LEDs to blink latch on or latch off Refer to the control panel technical for sensor LED status operation and expected delay to alarm detectors shall be low profile ceiling mount and wall mount capable and constructed of a UV resistant with multiple color options The detectors shall be plug in mounted into a twist lock base and from the mounting base to simplify installation service and maintenance Mounting base wiring shall be made by means of SEMS screws The detector shall allow prewiring of the base The base shall be mounted on a junction box which is at least 1.5 inches 3.81 cm deep The base shall be available to mount to standard junction boxes Suitable boxes include 4.0 10.16 cm square box with and without plaster ring 4.0 10.16 cm octagonal box 3.5 8.89 cm octagonal box Single gang box Agency Standards ANSI UL 268 Smoke Detectors for Fire Alarm Signaling Systems FM 3230 3250 Smoke Actuated Detectors for Automatic Fire Alarm Signaling ANSI UL 521 Heat Detectors for Fire Protective Signaling Systems FM 3210 Heat Detectors for Automatic Fire Alarm Signaling 2018
