JTWB-BCD-5151EIS 型点型感温火灾探测器（防爆型）
安装、维护及使用说明书
安装探测器之前，请仔细阅读本说明书，以便正确地使用和维护探测器。
概述
JTWB-BCD-5151EIS 型感温（防爆型）火灾探测器是一种传统型两线本质安全型感温探测器。设计这类探测器是为了对开放式区
域提供保护，且需与兼容的控制器(接口模块)配套使用。探测器采用现代工艺技术的热敏元件快速反应电路。可适用于各种恶劣环境，
维护简便，故障率低。探测器的2个红色的LED灯正常状态每5秒闪烁一次，故障状态不闪烁；报警状态时锁定恒亮，报警的复位可由瞬
间的断电来实现。探测器设计有门灯输出及供报警测试用的内置磁干簧管测试开关。
此型探测器为本质安全型防爆产品，符合GB3836.1-2000《爆炸性气体环境用电气设备第1部分：通用要求》和GB3836.4-2000
《爆炸性气体环境用电气设备第4部分：本质安全型“i”》的有关规定。它可用于有可燃性气体存在的危险环境。

在探测器安装后或定期维护后必须进行测试。本型号探测器可按以下步骤测试：
A. 测试磁铁
1. 将磁铁置于外壳上与测试标识相对边的位置处( 见图 1 )。
2. LED 应在 10 秒钟内锁定恒亮。如果 LED 未亮，检查探测器电源及底座接线。
3. 在系统控制器上复位。
B．直接加热法（1000－1500W 电吹风）
将热风直对探测器侧边（见图 1），热源距探测器保持 15cm 左右距离，以免损坏外壳。
注意：
1、如果探测器报警。只有等到其冷却下来并使其电源瞬间中断方可复位。检查所使用的控制器确定复位开关（或其它辅助设备）
是否将探测器回路的电源短暂切断。
2、如果用非本质安全方法进行测试，操作必须在危险环境以外进行。
以上测试不合格的探测器应按本文“维护保养”一节所述进行清洁处理，而后再进行测试，如果探测器还不能通过这些测试，则应
返回维修。
维护保养
本探测器从设计上是按尽可能免维护进行的，然而，一般空气中的浮尘会日积月累附着在探测器的敏感元件上并导致其灵敏度下
降。每年应对所有探测器至少进行一次的测试和清理，而在灰尘较大场合使用的探测器应更频繁测试和清理。发生火灾后必须立即清
洁并测试探测器。清洁之前，通知有关管理部门系统将进行维护，因而要临时停止工作。切断将进行维护的区域或系统的逻辑控制功
能，以免无谓的报警联动。
注意：维修时不能随意更换或改动影响防爆性能的元器件和结构。可按以下步骤进行清洁处理：
1、 从底座上卸下探测器。
2、 用吸尘器清理探测器室内的浮尘、杂物。
3、 重新安装探测器。
4、 按“测试”一节所述对探测器进行测试。

Sensor.
GENERAL DESCRIPTION
JTWB-BCD-5151EIS/HT is a conventional 2-wire intrinsically safe thermal detector. This detector is designed to provide open area
protection and to be used with compatible panels (or interface module) only. This sensor utilizes a state-of-the-art thermistor sensing
circuit for fast response. It can be used in every environmental condition and also has the simple maintenance and lower fault rate
advantages. Two red LEDs blink in standby each 5S and latch on in alarm, and do not blink in trouble. A remote output option is also
available. A built in test switch is used in the detector for test alarm. The detector is commpliance with the GB3836.1-2000
&GB3836.4-2000 standards requiremets.
INSTALLATION
NOTE: All wiring must comply with all applicable national codes of practice and regulations.
WARNING: Disconnect the power to the initiating device before installing the detectors.
1. Install detectors:
a. Place the detector into the detector base.
b. Turn the detector clockwise until the detector drops into
place.
c. Continue turning detector clockwise to lock it in place.
Tamper Resistance: T he d etector b ases can be made tamper
resistant. Whe n capabilit y is enabled, de tectors cannot be removed
from the base without t he u se o f a tool. See the detector base
installation ma nual of the de tector base for details in us ing this
capability
2. After all detectors have been installed, apply power to the control
unit.
3. Test the detector using the magnet as described under TESTING.
4. Reset the detector at the system control panel.
5. Notify the proper authorities that the system is back on line
.
TESTING
A. Test Magnet
1. Place the magnet against the cover in the location designated by
the raised mark to activate the test feature (see Figure 1).
2. The LEDs should latch ON within 5 seconds indicating alarm and
an-nunciating the panel.

3. Reset the detector at the system control panel.
B. Direct Heat Method (Hair dryer of 1000 - 1500 watts)
From the side of the d etector, direct the heat t oward the sensor. Hold the h eat source ab out 15 cm away to prevent da mage to th e
cover during testing
NOTE: If a detector goes into alarm, it will reset only if the detector has cooled and if its power is momentarily interrupted. Check the
control panel being used to determine whether the RESET switch (or some other auxiliary device or control) momentarily cuts off power
to the detector loop.
Detectors that fail these tests should be cleaned as desc ribed under M AINTENANCE and retested. If the detectors still fail thes e test s
they should be returned for repair.
MAINTENANCE
The JTWB-BCD-1151EIS/HT det ector has been designed to b e as m aintenance free as possible . Normal ai r-borne d ust, however, can
accumulate on the detector’s sensing elements and cause them to become less sensitive. All detectors should be tested and cleaned at least
once a year, and those in dustier areas should be tested and cleaned more often. Detectors must also be cleaned and tested immediately
after a f ire. Before c leaning, notif y the proper authorities that the system is und ergoing maintenance, and therefore the system w ill
temporarily be out of service. Disable the loop or system undergoing maintenance to prevent unwanted alarms.
1. Remove detector from mounting base.
2. Use a vacuum cleaner to remove dust from the sensing chamber.
3. Reinstall the detector.
4. Test detector as described under TESTING.
