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. When capability is enabled, detectors 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 toward the sensor. Hold the h eat source about 15 cm away to prevent damage 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 MAINTENANCE and retested. If the detectors still fail these tests
they should be returned for repair.
MAINTENANCE
The JTWB-BCD-1151EIS/HT detector has been designed to b e as maintenance free as possible. Normal ai r-borne dust, 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 cleaning, notify 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.
