                                    Smoke Alarms
                                    Model 9120B

Single Button Test/Silence eliminates confusion. Depending on what mode the alarm is
in, pushing the button provides different functions such as testing the alarm, silencing the
alarm, re-testing the alarm when in silence and clearing the Latching feature.

Latching Alarm Indicator easily identifies initiating alarm even after the alarm condition
has subsided.

Question: How do I test the 9120 Series Alarm?
Answer: The Single Button Test/Silence feature makes it easy to test the
alarm individually and when interconnected. Single Station Alarms: Test
each smoke alarm. Press and hold the Test/Silence button until the unit
alarms.
Alarms in an Interconnected Series: Press and hold the Test/Silence
button until the unit alarms (about 3 seconds). All interconnected alarms
should sound.

 Important Note: Only the interconnect signal is tested on the other
alarms. It does not test each alarm’s chamber operation.

***You must test each alarm individually to check if the alarm is
functioning properly***

This is true of all UL listed smoke alarms.
Key Note: The 9120 series alarms will stop testing immediately upon
releasing the test button. This improvement was added to make it easier
for inspectors and homeowners to silence the unit quicker. No more
going through a complete horn pattern after the button is released.

Question: What visual indications do I get during testing of an alarm?
Answer: On tested alarm Red LED flashes rapidly
On all other alarms Green LED(s) on, Red LED is off

Question: How do I silence smoke alarms in an interconnected series:
Answer: The 9120 Series (BRK/First Alert smoke alarms) to silence
multiple alarms in an interconnected series, you must press the
Test/Silence button on the unit(s) that triggered the alarm.
Note: The red LED on the initiating alarm will flash rapidly. The red LED
will be off on all other non-initiating alarms. The unit will exit “silence
mode” in approximately 10 minutes. While the unit is in “silence mode”
pressing and holding the Test/Silence button for approximately 10
seconds will test the unit. After testing, the unit will reenter “silence
mode” and the 10-minute timer will start over.

Question: How does the “Latching Alarm Indicator” work on the 9120
Series alarms?
Answer: On the 9120 Series Smoke Alarms the “Latching Alarm Indicator”
is automatically set when an alarm is initiated. When the alarm condition
has subsided the “Latching Alarm Indicator” is set only on the alarm(s)
subjected to the nuisance issue. This feature improves homeowner
satisfaction by allowing for easy contractor troubleshooting of nuisance
alarms with minimal time in the home. No more wasted time and money
removing all alarms to resolve a homeowner’s concern. The green LED
indicator will be on for two seconds/off for two seconds, repeatedly until
pushing the Test/Silence button resets the “Latching Alarm Indicator”.
After an Alarm (Latching):
On initiating alarm(s) Green LED on for 2 seconds/off for 2 seconds
On all other alarms Green LED on, Red LED is off



Regular Maintenance:

Use only the replacement batteries listed below. The unit may not operate properly with other
batteries. Never use rechargeable batteries since they may not provide a constant charge.

If the Smoke Alarm becomes contaminated by excessive dirt, dust and/or grime, and cannot be
cleaned to avoid unwanted alarms, replace the unit immediately.

When the battery back-up becomes weak, the Smoke Alarm will “chirp” about onec a minute
(the low battery warning). This warning should last 7 days, but you should replace the battery
immediately to continue your protection.

This Smoke Alarm requires one standard 9V battery. The following batteries are acceptable as
replacements: Duracell #MN1604, (Ultra) #MX1604, Eveready (Energizer) #522, Eveready
(Energizer) #1222, You may also use a Lithium battery like the Ultralife U9VL-J for longer
service life between battery changes.
Battery Replacement

toward the outside of the Smoke Alarm.
