EXPERT4HOUSE WHS101 Wireless Photoelectronic Smoke Detector
PRODUCT INTRODUCTION
This product is a photoelectronic smoke and heat detector, hereafter called a detector. With a unique structure design and an intelligent MCU to process photoelectronic signals, it is provided with dust-proof, mothproof and anti- light interference etc. functions, ensuring the detector stability from a design basis. It reacts very quickly to visible smoke released by smouldering fire and flaming fire. It has a photoelectronic smoke sensor and heat sensor inside, the detector will alarm when the temperature is up to 57 C or the smoke reaches the alarm level. It’s suitable for fire alarms in houses, factories, shopping malls, hotels, restaurants, office buildings, teaching buildings, banks, libraries, warehouses, etc..
PRODUCT PROFILE
Note
If not equipped with the wire assembly, the detector is a DC TYPE.
OPERATING PRINCIPLE
This detector adopts the principle of smoke particles reflecting infrared lights. The main circuit includes an MCU processing part, an infrared emission part and an infrared reception part. The emission and reception diodes are placed in the optical maze chamber which can shield the interference of outside stray lights, but will not influence smoke entering into the detector. In smokeless conditions, the received infrared lights are very weak. When smoke enters, due to scattering effects, the received light signals increase. When smoke density accumulates and reaches the alarm threshold of the MCU, the detector will blink its alarm indicator, give out a strident alarm sound and send out an alarm signal to the networking alarm system.

INSTALLATION
- Avoid installations in places with stagnating smoke, heavy dust, heavy water mist, heavy oil mist, great humidity (>95%) and high wind speed (>5m/s).
- Insert the ready battery into the battery cabinet. The AC power wire connects with AC power, the white wire connects with the AC L wire, black wire connects with the AC N wire. (AC TYPE).
- The yellow wire is a wired interconnected wire. Choose a proper position. Normally, the centre of the detection area ceiling is recommended.
- Fix the detector base into the chosen position and connect the wires if the detector is an AC TYPE. Then put the detector into the base and twist it to fasten it. Be sure it is fastened tightly.
OPERATING INSTRUCTION
Function Setup
Jumper Setting: use jumpers to set the address code and defence zone code
between the detector and the networking alarm system. AO~A7 are address codes
that should be the same as those of the networking alarm system. DO~D3 is the
data code, used to set defence zones.
Usage
- Inserting the ready battery into the battery cabinet and keeping the battery power supply,
- Connecting the AC power wires (for AC TYPE), the detector will enter into normal working status. The indicator flashes once per 40 seconds.
- Sensitivity Test The detector should be tested periodically to ensure normal operation. Once per month is recommended. Press and hold the TEST & HUSH BUTTON for more than Is to make the detector enter into testing status. If the alarm indicator flashes rapidly and the buzzer gives out an alarm sound, then the detector works properly.
- Alarm & Hush Function When the smoke density in the surroundings reaches the alarm threshold of the detector, the buzzer gives out an alarm sound and the alarm indicator flashes rapidly. At this time, pressing the TEST & HUSH BUTTON will make the detector enter into mute status that lasts for 10 minutes. During this period, the indicator flashes once per 10s and if the density is still higher than the threshold, the TEST & HUSH BUTTON is nonfunctional. When the smoke density goes below the threshold, pressing the TEST & HUSH BUTTON will activate the detector to perform testing operations. After 10 minutes, the detector recovers automatically to normal working status.
- Networking to Alarm System Press the TEST & HUSH BUTTON and the detector will send out an alarm signal. If using learning code alarm systems, under learning mode, users can program the detector into the alarm system by pressing the TEST & HUSH BUTTON. When an alarm occurs, users can see the alarm information from the system and take corresponding countermeasures to reduce losses.
- Malfunction Check When the detector buzzer gives out a Di sound every 40 seconds along with the alarm indicator flashing once, the battery voltage should become lower than the detector’s normal operating voltage. At this time, replace the battery with a new one. Otherwise, it will influence the detector’s normal operation.
- If the buzzer gives out 2 Di sounds every 40 seconds along with the alarm indicator flashing twice, the infrared photoelectronic sensor should malfunction. Pls, contact the dealer in time. Do not attempt to remove and repair the detector personally to prevent incidents.
JUMPER SETTING SKETCH
NOTE
- Perform the SENSITIVITY TEST as requested.
- Clean the detector surface with a soft-bristled brush every 6 months to ensure the detecting sensitivity. Remember to cut off the power source before cleaning.
- If the detector is not used for a long time, remove the detector, take out the battery from the cabinet and store it in a cool and dry place.
- The detector can reduce the happening rate of disasters. But it can not guarantee a hundred per cent safe.
- For safety considerations, pls use the detector properly and heighten vigilance and safety consciousness to take preventive measures.
