Features
Battery and Low Battery Detection
The SDCO-1 uses three EL123AP Lithium Batteries as its power source. The batteries are included in the package.
The SDCO has a foolproof mechanism which prohibits cover closure without first installing battery.
When the SDCO is low on battery, a low battery signal will be transmitted along with regular signal transmissions. The Amber LED
will flash with a low-volume beep once every 45 seconds.
Both Red and Amber LED will flash once every 4 seconds when batteries are extremely low and needed to be replaced.
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:
Use a Phillips screwdriver to loosen the battery compartment fixing screw, and remove the battery compartment cover.
Step 2:
Insert 3 batteries into the battery compartment.
Step 3:
The SDCO Detector will emit 2 short beeps, and begin warm up process for
1
minute. LED will flash every 2 seconds.
Step 4.
During the 1 minute period, learn in the Smoke Detector.
a. Press the Learn/Test button once to transmit an IR sensor learn code.
b. Press and hold the Learn/Test button for 3 seconds to transmit a Smoke/Temperature sensor learn code
(step a. and step
b. are both required for serial connected models)
.
If the Control Panel receives the signal, the Smoke Detector will emit a 2-tone beep. Refer to Control Panel manual to
complete learning process.
Step 5:
When 1-minute warm up period expires, the SDCO Detector will emit a beep to indicate it now enters calibration process. The
calibration process takes 1~7 minutes; the LED will continue to flash during calibration.
Step 6:
When calibration is complete, the SDCO Detector will emit a 2-tone sound and LED will stop flashing to indicate it is now under
normal operation. If calibration fails, the SDCO Detector will sound continuous beeps.
Alarm Detection
The SDCO Detector will activate fire alarm when either of its smoke detection or high heat detection function is triggered. When an
alarm is activated, the SDCO Detector will transmit alarm signal and raise alarm with its built-in buzzer. The Red LED will flash rapidly.
Smoke Detection:
The SDCO Detector checks smoke concentration every 8 seconds
Whenever the smoke concentration exceeds the detection threshold, SDCO will send active signal to the Control Panel, and
activate the alarm.
If the smoke concentration persists, the SDCO Detector will continue to send the active signal every 2 minutes to the Control
Panel.
If no smoke is detected for 20 continuous detection times, the SDCO will transmit a restore signal and stop the alarm.
Heat Detection (For SDCO-1H-F1 and SDCO-1H-F1-2W models only):
The SDCO 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).
If no high heat is detected for 20 continuous detection times, the SDCO will transmit a restore signal and stop alarming.
If the alarm was triggered by High Heat condition (57.25°C), the temperature must drop below 49°C for the Detector to stop
alarming.
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.
Carbon Monoxide Detection:
The CO sensor checks the CO concentration level every 16 seconds. If the concentration level exceeds the detection threshold,
the SDCO Detector will transmit alarm signal and raise alarm with its built in buzzer.
The CO sensor features self-diagnosis function and will regularly check the health or status of the sensor every 12 hours.
The alarm will be activated after CO concentration is detected according to time length in the following table: (compliant with
EN-50291 standard)
CO concentration level
Time taken before alarming
30 +/- 10% ppm
N/A
50 +/- 10% ppm
60~90 minutes
100 +/- 10% ppm
10~40 minutes
300 +/- 10% ppm
Under 3 minutes
The alarm will be activated after CO concentration is detected according to time length in the following table: (compliant with
UL-2034 standard)
CO concentration level
Time taken before alarming
30 +/- 3% ppm
N/A
70 +/- 5% ppm
N/A
70 +/- 5% ppm
60~240 minutes
150 +/- 5% ppm
10~50 minutes
400 +/- 10% ppm
4~15 minutes
Once the CO concentration level exceeds the threshold and persists for the time length as listed in the above table, the SDCO
Detector will transmit the signal to the Control Panel and raise alarm with its built-in siren.
Testing the SDCO Detector
By pressing the Test Button on the SDCO Detector, you can test if the SDCO is functioning normally.
If the SDCO Detector functions normally, the Red LED will flash once followed by a 2-tone beep.
If three 2-tone beeps (DO-DI DO-DI DO-DI) are emitted, it means the Smoke Sensor is out-of-order.
