VI-6631 Intelligent
Fixed Temperature Heat Detector
Installation and Operation Manual (Ver1.03，August 2014)
1. Description
VI-6631 Intelligent Fixed Temperature Heat Detector (called the detector for short) using
excellent MCU technology can accurately chase with the variation of environment temperature,
detect fire in-time, and generate fire alarm.
The detector has pleasing appearance and is easy to install and maintain. It is suitable for the
environment without smoke but a lot of dust or the places where smoke and vapor stay such as
indoor parking, kitchen, boiler room, tea stove room, generator room and drying workshop.
2. Features
(1) Built-in ID address of the detector.
(2) Filter designed in both software and hardware, enhance anti-interference ability of the
detector.
(3) Two-wire loop, non-polarized.
(4) Utilizing electronic addressing, makes programming more flexible, simple and user-friendly.
(5) PCB board is sealed totally.
(6) Use thermal components with high sensitivity, enhancing response speed to variation of the
temperature.
(7) Talented design of structure without a single screw.
3. Technical Specifications
(1) Operating Voltage：15V-28V impulse voltage
(2) Operating Current:
1）Loop static current ≤0.5mA
2）Loop alarm current ≤1.0mA
(3) Sensitivity: A2
(4) Wiring: two-wire（non-polarized ）
(5) Programming: Electronic addressing
(6) Status Incitation of the detector.
1）Standby: LED flashes periodically.
2）Fire: LED illuminates steadily.
3）Fault warning: LED is off until cleared.
(7) Operating Environment
a) Temperature:-10℃～54℃
b) Humidity: ≤93±2%RH（25℃-40℃），non-condensing
(8) Color: Gloss-White
(9) Weight: 120g
(10) Standard: GB 4716-2005
4. Structure and Operation Principle
(1) Dimension of the detector is shown in Fig. 1 and Fig. 2 separately.

Fig. 1
Fig. 2
(2) Operation Principles
This product uses the thermistance of negative temperature index. When the temperature rises,
the resistance of thermistor is decreasing, which lead to the change of voltage. When the voltage
value is bigger than threshold, it reports alarm signal, and the code-returning circuit transmits the
signal to the fire alarm control panel and generates the fire alarm.
5. Installation and Cabling
Warning: Please disconnect the loop power and verify all the detectors are fixed securely
before installing the detector.
(1) Mounting
Mounting of the detector is shown in Fig. 3.
Fig.3

Back box is standard 86H50 box. The detector can be installed onto the base as align the
Z-shaped piece to the base and rotate clockwise when installing.
(2) Wiring Requirement
RVS-2*1.0 mm2or1.5 mm2wire for LOOP, laid through metal tube (cable sink) or PVC tube.
(3) Connection Description
Connection is shown in Fig.4.
Fig. 4
6. Operation
Address Programming: Using VI-6631 Hand Held Programmer can program address of the
device in field. When programming, first connect two alligator clips of the hand held programmer
to the loop-ports of the detector; second, switch on power of the programmer and enter
addressable code (code should be from 0 to 255. The device connected to the same loop has
unique address. Third, press Program. Programming is successful if the address which you wrote
appears on the left of the display. Otherwise, the programming is failed.
Please refer to V6531 Handheld Programmer Installation and Operation Manual for specific steps
and description.
7. Handling and Storage
The device should be packed totally when it is transported, handled and stocked. Handle is
gently impact and avoid when loading and unloading. Storage environment for the devices
should be dry and ventilate. Don’t place them in an open environment.
The equipment should be packed well when it is transported, handled and stocked. Loading and
Unloading gently to avoid any collision. The environment of storage should be dry and ventilate.
Do not explose it in an open area.
8. Cautions
(1) After installation, please keep the dust-cover on, until complete of commissioning test or
project inspection, so as to avoid any contamination occurred.
(2) If the detector gives fault warning after a long operation, first check if the detector are

damaged, or the position is changed.Afterwards, other faults should be considered.
(3) The duty person should be trained to properly operate the device, and disoperation is not
allowed.
(4) The detector is fire protection product, so the duty and shift rules should be carried out and
made the record carefully.
(5) A routine functional test should be conducted every 6 months when the detector is operating
on.
(6) Please put on the dust cover if the room is under decoration or wall-painted to avoid
contamination.
