SD-32 Smoke Detector Series
SD-32 Series is a wireless smoke detector designed to protect you against potential fire hazards. The Smoke detector uses multi criteria sensor technology for detecting between fast burning flames and slow smoldering fires, while at the same time includes intelligent technology to differentiate between cooking smoke and actual life-threatening house-fire emergencies, virtually eliminating nuisance alarms.
In addition to the capability of smoke detection, the models with heat detection are capable of reporting temperature to users. The models built-in the PIR motion sensor are capable of detecting movements. The SC model can be interconnected with other smoke detectors in the alarm system and will raise alarm when any smoke detector in the system is triggered.

Features
Battery
Three CR123 3V Lithium batteries are used to supply power to the Smoke Detector.
The Smoke Detector has a foolproof mechanism which prohibits cover closure without first installing battery. Press down the tab and insert three new batteries into the compartment.
The Smoke Detector will automatically check battery voltage every 25 seconds. If low battery is detected 2 times in a row, the Smoke Detector will transmit a low battery signal and enter low battery status.
Under low battery status, low battery signal will be transmitted along with regular signal transmissions; the Orange LED will flash once every 45 seconds.
The Red and Orange LED will flash once every 4 seconds when the battery is exhausted.
<NOTE>
When changing the batteries, after removing the old batteries, press the Test Button twice to fully discharge before inserting new batteries.
Getting Started
Step 1. Insert three CR123 3V Lithium batteries to power on the Smoke Detector. Orient the battery according to the battery compartment polarity before insertion.
Step 2. The Smoke Detector will emit 2 short beeps and begin warm up for 1 minute. The Red LED will flash every 2 seconds. Step 3. When the Smoke Detector completes warm-up, it will emit a beep to indicate it has entered calibration mode. The calibration
mode lasts for 1 minute (If calibration fails, the smoke detector will retry calibration, calibration mode will last 9 minutes at most). The Red LED will continue to flash every two seconds during calibration.
Step 4. When calibration is completed, the Smoke Detector will emit 2 short beeps and turn off LED to return to normal mode.
<NOTE>
If calibration fails, the Smoke Detector will beep continuously. Please remove the battery, press the Test Button twice to fully discharge, and then reinsert the batteries to retry from step 1.
After warm up and calibration process are successfully completed, you can proceed to learning.
Step 5. Put Control Panel into learning mode. Refer to Control Panel manual for details.
Step 6. (For non-SC model) Press the Learn/Test button once to transmit learning code.
(For SC model) Press the Learn/Test button for 3 seconds to transmit all learning code(s).
Step 7. Immediately add the detected sensor(s) to Control Panel.
<NOTE>
For SC model, the Smoke Detector will emit a 2-tone beep upon receiving acknowledgement from the Control Panel for Smoke/Temperature sensor learn code.
Testing the Smoke Detector
By pressing the Test Button on the Smoke Detector, you can test if the Smoke Detector is functioning normally.
If the Smoke Detector functions normally, the Red LED will be on for 2 seconds followed by a 2-tone beep.
If the buzzer sounds 2-tone beeps 3 times, the “Optical Chamber” on the Smoke Detector is either dirty or out-of-order.
Test Mode for IR Function (SD-32-HM/-HM-SC only)
The device’s PIR Motion Sensor can be put into Test mode by pressing the Test Button. Every time the Test Button is pressed, the device will transmit a test signal to the Control Panel for radio range test and enter the test mode for 3 mins. It will exit Test Mode automatically after 3 minutes and return to normal mode. In Test mode, the sleep timer is disabled, and the LED indicator will flash every time a movement is detected.
Sleep Timer of IR Function (SD-32-HM/-HM-SC only)
The device’s PIR Motion Sensor has a “sleep time” of approximately 40 seconds to conserve power. After transmitting a detected movement, the PIR will not retransmit for 40 seconds. In this way continuous movement in front of a PIR will not unduly exhaust the battery.
Supervision
The Smoke Detector will transmit a supervision signal to report its condition regularly according to user setting. The factory default interval is 30~50 minutes.
Temperature Detection (SD-32-HM/-HM-SC only)
The Temperature Sensor measures temperature every 10 seconds, and transmits temperature reading to the Control Panel every 30~33 minutes.
Users can also press the Test Button once to transmit current temperature reading manually.
Alarm Activation
The Smoke Detector will activate fire alarm when smoke detection is triggered. The models with heat detection will also activate alarm when high heat is detected. When an alarm is activated, the Smoke Detector will transmit alarm signal and raise alarm with its built-in buzzer.
Smoke Detection:
The Smoke Detector checks smoke concentration every 8 seconds
The alarm is activated whenever the smoke concentration exceeds the detection threshold, and will continue until the smoke concentration drops below alarm threshold.
The Red LED will flash quickly during alarm.
Heat Detection: (SD-32-HM/-HM-SC only)
The Smoke Detector checks temperature every 10 seconds. The alarm will be activated in the following conditions:
When the temperature rises by 8.25°C per minute (Rate of Rise).
When the temperature exceeds 57.25°C (High Heat).
2
The Red LED will flash every second during alarm. The Smoke Detector will only stop alarming if the temperature drops below alarm threshold:
If the alarm was triggered by Rate of Rise condition (8.25°C per minute or more), the temperature must drop to 4°C below highest temperature detected for the detector to stop alarming.
If the alarm was triggered by High Heat condition (57.25°C), the temperature must drop below 49°C for the Smoke Detector to stop alarming.
The Smoke Detector will transmit a restore signal if no smoke or high heat is detected for 160 seconds.
If the alarm condition persists, the Smoke Detector will resend alarm signal every 2 minutes.
IR Detection: (SD-32-HM/-HM-SC only)
The Smoke Detector will transmit signal to the Control Panel if any movement is picked up within the IR detection coverage. The buzzer will not sound and the LED will not flash. Please refer to your Control Panel for details.
Interconnection (SD-32-HM-SC only)
The Smoke Detector is interconnected with other Smoke Detectors in the alarm system. When a Smoke Detector activates alarm, the Control Panel will notify other Smoke Detectors to also raise alarm even if they have not detected smoke yet. The alarm length will be in accordance with the Control Panel’s setting.
Disarming the system will stop alarm of other Smoke Detectors activated by the Control Panel. The alarm triggered by the Smoke Detector that detects smoke will only stop when the smoke concentration drops below alarm threshold.
Pressing the Test button of a smoke detector will only silence alarm of that specific smoke detector, but cannot silence alarm of all interconnected Smoke detectors.
Alarm Silence
When the Smoke Detector is alarming, pressing the Test button will put the Smoke Detector into Alarm Silence mode to silence the alarm for 9 minutes. The buzzer will only stop sounding after the alarm has been activated for at least 1-minute. If the button is pressed before alarm time reaches 1 minute, the Smoke Detector will wait until alarm time has reach 1 minute before silencing the alarm.
During the 9-minute Alarm Silence period, the Red LED will flash once per second. The Smoke Detector will continue to monitor smoke concentration during the alarm silence period:
After the 9-minute Alarm Silence period has expired, if the smoke concentration has dropped below alarm threshold, the Smoke Detector will emit a 2-tone beep and return to normal operation without sounding alarm.
If smoke concentration still exceeds alarm threshold, the Smoke Detector will start alarming again.
If smoke concentration continues to rise during Alarm Silence period and exceeds a second alarm threshold, the Smoke Detector will start alarming again. An alarm activated by exceeding the second alarm threshold could not be silenced by pressing the test button.
Recalibration
As the operation condition of the Smoke Detector may vary after being installed for some time, you may wish to recalibrate the Smoke Detector to take a new smoke detection threshold value and ensure optimal performance of the Smoke Detector. To do this:
Press and hold the Test Button for 10 seconds and release when the Smoke Detector emits 2 beeps. The device will sound another beep after 5 seconds and begin calibration. The Red LED will flash every 2 seconds to indicate.
Calibration process lasts for 1 minute (If calibration fails, the smoke detector will retry calibration, calibration mode will last 9 minutes at most).
When calibration is finished, the Smoke Detector will sound a two-tone beep. The Red LED will stop flashing to indicate it has returned to normal mode.
If calibration fails, the Smoke Detector will beep continuously, and the Orange LED will flash every second. Please remove the battery, press the Test Button twice to fully discharge, and then reinsert the batteries to restart Smoke Detector.
