Longsin LS-858-11 Operating Manual

Product Overview
This product is the high stable Carbon monoxide detector
(below abbr as the detector), it use for detecting the
leakage of the carbon monoxide. It is made of the most
advanced electrochemistry carbon monoxide sensor, it
with high stability, sensitivity drift small such character.
This product use the backlit digital LCD to display the
alarm level. The detector can operates with the voltage
between AC110-230V, after installing with the standby
battery function. When the detector detects the carbon
monoxide leaks and the thickness reach the default
alarm level, the detector red LED ash and sounds. This
product suits for the all the places that might produce the
carbon monoxide.

Wiring installing instruction
All the wiring installing need to follow the national or the
local law and standard. The thickness of the wire stylet
need to be properly. the improperly connection may lead
the detector does not alarm when the carbon monoxide
leak.

Product Installing
1. This product suits for plug type mounting and wall
mounting, choose the properly place, generally on
the ceiling above where have the carbon monoxide,
the distance is about 2m.
detector
detector
gas stove
2. Static the installing support x on the ceiling, and
insert the detector on the installing support. Or choose
the place where there is the plug board, and plug the
detector on the plug board directly.
3. Home usage detector need to avoid installing near the
gas stove, to avoid the detector be heated by the re
from the stove; avoid install in the place where has
strong smoke, it might lead false alarm or effect the
detector sensor's sensitivity; avoid install near the
ventilating fans, windows and bathroom these high air
ow areas.
4. The wiring connects need to follow the installing
diagram, all the wiring need to follows the national and
local laws, standards. The wiring thickness should be
properly, the wiring connects the detector and the
other assisted device should be marked colors, to
avoid connect wrongly. The improperly wiring
connection might lead the detector don't alarm
correctly when it detect the leakage of the carbon
monoxide.
Operating instruction
1. Supply the detector with power. The detector enter
the auto-check status, the green LED, red LED, yellow
LED indicator ash 1 time at the same time, the buzzer
sounds 'di' 1 time. Then the detector enter the warm-up
status, LCD symbol display in turn, warm up need
about 60s, the LCD back light close, LCD display the
power supply and check the gas' chemical symbol, it
means the detector enter monitoring status. Warm-up
period prohibit use the gas to test. When the outside
AC power stop to supply, the detector will automatic
change the standby battery to supply. When the battery
volume is too low, LCD will display the low battery
volume mark, the green indicator will ash 1 time every
12s,and with the buzzer sounds 1 'di'.
