D-302894 SMD-426 PG2, SMD-427 PG2 Installation Instructions 5
3. SMOKE DETECTOR TEST
Notes:
i) Insert the battery and then mount the detector on the bracket before conducting the smoke detector test.
ii) After the battery is inserted, the detector enters the Local Diagnostic Test Mode for 15 minutes.
iii) It is recommended to test the detector when conducting the Periodic Test using the User Code (User Diagnostic Mode) or when conducting
the Periodic Test using the Installer Code (Installer Diagnostic Mode).
Caution! The diagnostics test cannot be performed while tamper is in "open" state.
Enter the test mode by pressing the test button for 2 seconds and release it. In this mode, the detector will test smoke, heat and battery functions.
If all functions are good, the red LED lights 0.5s, off 0.5s, the yellow LED lights 0.5s, off 0.5s followed by a loud 3-beep alarm and the red LED
flashes simultaneously. Otherwise, the detector produces the warning signals as detailed in Table 1.
If the detector is in any diagnostics mode (see Notes above), the detector performs the diagnostics test as described below.
Diagnostics Test
A. The detector performs a communication quality test and visual indication by LED (lights orange).
B. When the LED lights orange (red and green), this indicates correct operation of the LEDs.
C. The detector now performs the link quality test.
Note: If the detector is not in local diagnostics or installer diagnostics mode, the detector will not perform the link quality test.
D. At the end of the diagnostics test the LED blinks 3 times.
The following table indicates received signal strength indication.
LED response Reception
Green LED blinks Strong
Orange LED blinks Good
Red LED blinks Poor
No blinks No communication
IMPORTANT! Reliable reception must be assured. Therefore, "poor" signal strength is not acceptable. If you receive a "poor" signal from the
detector, re-locate it and re-test until a "good" or "strong" signal strength is received.
1. For detailed Diagnostics Test instructions refer to the control panel Installer Guide.
2. For UL/CUL installations, the test result must be “Strong”.
4. MOUNTING
1. Mark and drill 2 holes in the mounting surface. Fasten the bracket to
the mounting surface with 2 screws.
2. Align bracket tabs with the detector slots and rotate the detector as
shown. Pull the detector outward to verify that it is securely
attached.

Notes
1. A battery must be inserted into the detector before the detector can
be mounted onto the bracket.
2. Unauthorized removal of the unit from the bracket will initiate a
tamper alert!
5. SMOKE DETECTOR LIMITATIONS
A. This smoke detector is designed for use in a single residential unit or offices, which means that it should be used inside a single family home or
apartment or office.
B. Please refer to NFPA 101, the Life Safety Code, NFPA72 for smoke detector requirements for fire protection in buildings not defined as
"households".
C. The smoke detector will not sense a fire if the smoke does not reach the sensor. In order for a smoke detector to sense smoke, it must be
installed in the immediate vicinity of the fire.
In addition, smoke from fires in chimneys, in walls, on roofs, in remote parts of the building, or on another level from where the smoke detector
is located, may not reach the smoke detector quickly enough for occupants to escape unharmed. For this reason, installer shall install
smoke detectors on every level, in every sleeping area and in every bedroom of the household.
D. Smoke detector may not be heard. The alarm horn in this smoke detector meets or exceeds current Underwriter’s Laboratories standards.
However, if the smoke detector is not located in the same room as the occupant or if it is blocked by a closed door or normal noise, the alarm
horn may not be heard. In addition, sound sleepers, or persons who are under the influence of drugs or alcohol may not hear the alarm or be
able to react to it. Therefore, locate this smoke detector, which has a sounder rated at 85 dB at 10 feet, on every level, in every
sleeping area and in every bedroom of the household.
