Fixed temperature and rate of rise alarming modes.
Fire LED allows 360°viewing.
Remote indicator output available.
Reed switch testing.
Comply with EN54-5 standard.
Description
VG-6633 Conventional Heat Detector (the detector)is non-addressable, developed by our company. With built-in
microprocessor, it works stably by being fixed with highly reliable fire judging program.
When the detector checks fire signal, it can change its own current to transmit fire signal to control panel or interface
module. The detector keeps illuminating fire LED to indicate fire status until resetting.
NTC thermistor is adopted as sensing element for the detector.
Installation
The orientation base VG-6611 is shown in Fig. 3.
Fi
g. 1 Bottom Fig. 2 Base
There are four terminals with numbers on the base.
1: Detection zone positive IN
2: Detection zone positive OUT
3: Detection zone negative IN and OUT
2: Positive terminal of remote indicator
4: Negative terminal of remote indicator
Recommended Wiring:
1.0mm2 or above fire cable for all terminals, laid through
metal conduit or flame-proof conduit, subject to local
codes.
Note: It’s recommended to use cables of different
colors to avoid incorrect wiring.
First fix the orientation base with two tapping screws.
Then align A (Fig. 1) on the bottom of the detector to B
(Fig. 2) of the base, and rotate the detector clockwise to
mark C.
Mounting of the detector is shown in Fig. 3.

Application
Warning: The alarm current depends on the current limit of the FACP. 24VDC power cannot be applied to
the detector directly. Otherwise the detector may be damaged for lack of current- limit resistor.
The detector is applicable for many places such as
hotels, restaurants, office buildings, teaching buildings,
banks, warehouses, libraries, computer rooms and
switching rooms and so on.
When the detector is connected with VC-6831
conventional fire alarm control panel or the
addressable zone monitor unit, if a 4.7KΩ terminal
resistor is connected to the end of output loop, then
VG-6611 base is used. The system composition is
shown in Fig. 4.
