Instuction Mannal of JTY-GD-S832 Point-type
Photoelectric Smoke Detector
Please read through these instructions carefully before installation and use!
I. General
JTY-GD-S832 point-type photoelectric smoke detector is a photoelectric
smoke detector. As a non-polar two-wire power input is adopted in the detector,
it can detect the smoke and send out alarm signal in time when fire taking
place. As microcontroller is adopted in the detector, it can identify the smoke
concentration intellectually. The detector monitors smoke concentration in the
workplace in real time. While monitoring, the red indicator blinks and the
working current is low. When the work site smoke concentration has exceeded
the preset alarm threshold, the detector is alarming and the red indicator
remains on, relay is driven. The detector has the function of relay contact
output, alarm signal is shown as the change of relay contact output, alarm
signal can be kept and the alarm can only be reset by the instant power
disconnection. The detector has an automatic compensation function against
dust accumulation and can reduce the effect of dust on the sensitivity of the
detector.
The smoke detector is applicable in places where fire might generate
volume smoke, i.e. in industrial and civil buildings such as in the restaurant,
hotel, teaching building, office building, computer cabinet, archives and stack
room.

III. Installation and commissioning
Determine the location, mounting distance and numbers for mounting the
smoke detectors in the protection area in accordance to the relevant
stipulations of GB50116-98.
A base shown in figure 3 is required for mounting the smoke detector; its
exterior size is 75mm

The smoke detector connects with power and other device via 4PIN
Pluggable Terminal Block. As Shown in figure 4, D1 & D2 pins are the power
input terminals; K1 & K2 pins are the output terminals of the relay.
Fig.3 Fig.4
Details of the installation and commissioning are as following
：
1.
Installed base can be used as follows
：
1)
Prepare the shop drawing and fix the auxiliary base onto the
defined location with two M4 bolts installed through the two fixing
holes (A
、
B shown in figure
3).
2)
According to the shop drawing, use a drill to bore two
Φ
6mm holes
onto defined location, then put two expandable plastic stoppers into
the holes separately, fix the auxiliary base onto the defined location
with two ST3.5
×
20mm tapping screws installed through the two
fixing holes (A & B shown in figure 3);
3)
Magnet install into designated A, B fixed hole as shown in figure 3 ,
after the base and the detector assembly, adsorbed detector on the
metal cabinet or rack through the magnet, this installation could be
selected.
2.
Disconnect the power, connect all bases correctly as per the shop
drawing, and then connect the controllers to the corresponding input
ports.
3.
Make sure that all smoke detectors types correspond with the ones
noted in the shop drawing.
4.
To be installed and disassembled the smoke detector, as shown in figure
5 and figure 6.
Fig.5 Fig.6
5.
Don
’
t power on the controller until all smoke detectors have been
mounted correctly; to confirm correct, connect detector power supply.
First, the red indicator blinks once ,and then enter the normal state to
monitor about every 6 seconds blinks once, indicating that detectors
have begun working;
6.
Alarm test of the detector is performed by special tool or puffing smoke
directly. The red indicator remains on after the detector alarms. After
testing reset the detector to monitoring state.
7.
After the base and the detector assembly,
Internal termination

)
will be connected between the
output terminals of the
relay(K1,K2)
through the sheet metal on the base. Installation and
removal of the sheet metal, as shown in figure 7 and figure 8.
