This alarm will not operate until the long beep is heard immediately after removing the pull tab.
Press and release the test button. If the alarm sounds, it has been effectively activated.
If the alarm does not sound after pressing the test button, the alarm is not activated and will
not provide protection.
Repeat steps 1-11 above for installation of multiple interconnected alarms.
ELECTRICAL SHOCK HAZARD.
Do not restore power until all alarms are completely
installed. Restoring power before installation is complete may result in serious electrical shock,
injury or death.
If any alarm in the series does not sound during testing, turn off power, recheck connections
and wiring and confirm the battery pull tab has been removed. Restore power and re-test. If
there is still a problem, call customer service. Do not attempt to fix the alarm.
INTERCONNECTION & COMPATIBILITY
Interconnected alarms can provide earlier warning than stand-alone alarms, especially the
hazard occurs in a remote area of the dwelling. When alarms are interconnected, all alarms will
sound when one alarm first sounds.
To prevent damage, do not connect this alarm to any other type of alarm
or auxiliary device. Connecting incompatible devices or alarms may damage this alarm or
prevent it from operating properly.
This alarm may be interconnected with a total of not more than 24 interconnected devices, i.e.,
as many as 11 other USI Electric or Universal Security Instruments model smoke alarms or
combination smoke and carbon monoxide or smoke and carbon monoxide/natural gas alarms;
6 other initiating alarms which may be a combination of USI Electric or Universal carbon
monoxide alarms and heat alarms; and 6 other non-initiating devices such as USI Electric relay
modules.
This alarm can be interconnected with the following models and accessories: MDSCN111,
MICN109, MCN108, USI-1204, USI-1209, USI-1213, USI-3204, 5304, MI106, MDS107, MP117,
USI-2430, USI-960, MI106S, MIC1509S, MPC122S, MP116S, SLW127, AMI1061S,
AMIC1510S.
When any one of these interconnected models sounds, it will trigger the corresponding alarm
within the interconnected system with respect to their sensing capabilities. Natural gas
detection is only present in models MDSCN111, MICN109 and MCN108, therefore a natural
gas alarm will NOT trigger the alarm of non-natural gas sensing models within an
interconnected system.
The following alarms can trigger Quick Find
®
Alarm Origination, but will not indicate Alarm
Origination on an interconnected system: USI-1204, Part USI-1209, USI-1213, USI-3204,
USI-2430.
The following alarms cannot be reset through an interconnected system: USI-1204, USI-1209,
USI-1213, USI-2430.
11. Test the alarm. IMPORTANT: All interconnected alarms in the interconnected system
should sound. This test is only testing the interconnect signal between each alarm. It will
not test the operation of each alarm. To verify all alarms are operating correctly, press
the test button on each alarm individually.
