Shenzhen real Shenzhen zhenjingzhun technology co, LTD Tel: 0755-33168009 Fax: 0755-33168010 QQ: 1361688948 E-mail: saleszjz@163.com official website: http: / /www.china-zjz.com Address: Shenzhen Bao'an District, the town of San Tin Junda Industrial Park, Building A, third floor Spec Installation: Ceiling Application: temperature detection Applications: Household Type: temperature probe sensor operating voltage : 9-28V Brand: True Precision Model: ZJZ105 Specifications: Multi-line packaging: blister / carton Yield: 10000 Product details noncoding Heat Detector 2-wire current-traditional multi-line temperature probe can be connected with a sense of alarm Maintenance Replacing all multi-line control panel, and more for export or the old traditional fire protection system (NLE 2 bus), bus manufacturers by domestic fire input module (current type, after the alarm, low voltage, increasing the current) access to fire protection system. Multi-linear heat detectors (hereinafter referred to as detectors) suitable for shopping malls, hotels, shops, warehouses, motor housing and other civil and industrial sites pre-alarm fire. Detector with high sensitivity, stable and reliable, low power consumption, beautiful and durable, easy to use features. Note: The detector alarm when it is clamped at both ends of the voltage between 5V ~ 11V. As for the size of the current depends on the limiting case the controller does not allow the direct use of 24VDC power supply, otherwise the detector will cause an infinite flow resistance and burn. And multi-line control panel or control box shutter doors and other equipment for use during normal use. After the detector alarms to be reset by the way off. 2-wire connection, regardless of polarity, a plurality of detectors share a line, and another from a probe into a terminal from another out, N + 1 connection with anti-theft feature. One. Performance: Power supply: DC9V ~ DC28V Current: Static current ≤40uA Alarm current ≤30mA Operating temperature: -10 ℃ ~ + 50 ℃ Relative humidity: ≤95% RH (40 ℃ ± 2 ℃) temperature alarm level: A1R (limit 54 ℃ The upper limit of 65 ℃, constant temperature 57 ℃) standard: GB4716-2005 Weight: 155g II. Installation: The ceiling apart play two 5mm in diameter 60mm mounting hole position, with up plug and screw the detector base in the ceiling. III. Wiring: The detector has an external door light function, when the detector alarm, in addition to its own indicator light outside, but the door lights connection, especially for hotel use. Fourth, the wiring instructions: detector terminals 4,3 is the power input (not case polarity wiring), where terminals 2 and 3 short even inside the detector. Terminal 5 for shielding the connecting cable shield. Door lights can be used directly ordinary LED, located inside the detector current limiting resistor. Termination resistor size, based on multi-line controller mating may be. Detector test required 24VDC directly added, you must add a current limiting resistor 1KΩ. Base wiring is completed, the probe in the correct direction button on the base, after pressing tighten clockwise. Power can work. Other notes alarm temperature level: A1R (limit 54 ℃, the upper limit of 65 ℃, constant temperature 57 ℃) standard: GB4716-2005 Weight: 155g Shenzhen real Precision Technology Co., Ltd. is a high-tech company specializing in the research and production of smoke, separate smoke , networking smoke, smoke detectors, smoke alarms, smoke detection alarm system, smoke alarm, temperature alarm, gas alarm, fire alarm controller, smoke detectors, fire detection and fire alarms, and other fire alarm products.
