NB Smoke Multi detektor SD-29
Temperature Detection
(SD-29-H/SD-29-HM/SD-29-HME 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 either of its smoke detection or high heat detection function is triggered.
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:
•
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).
•
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-29-HM/SD-29-HME only)
•
The Smoke Detector will transmit signal to the Control Panel if any movement is picked up within the IR detection coverage.
The white LED will light up for 60 seconds upon movement detection.
Emergency Light (White LED)
(SD-29-HME only)
•
The Smoke Detector has a built-in emergency light that can provide visual alerts in case of emergency. When the Smoke
Detector is activated, the emergency light will begin to flash slowly to indicate the system is alarming.
•
When any movement is picked up within the IR detection coverage, the white LED will light up for 60 seconds.
Interconnection
(SD-29-HME-SC only)
•
The Smoke Detector is interconnected with other Smoke Detector 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.
•
You cannot press the function button to silence alarm activated by other Smoke Detectors.
•
Alarm will be restored only after 3 minutes timeout or until the other Smoke Detector which triggers alarm transmits a restore signal.
•
The interconnected Smoke Detectors can be controlled by the system panel to turn on their white LEDs according to the set
Home Automation Rules.
