Kidde 120V AC Wire-In Smoke Alarm with Battery Backup and Smart Hushi 12040
Kidde Hardwire With Battery Backup Photoelectric Smoke Alarm P12040
The Kidde P12040 is a photoelectric smoke alarm powered by 120VAC and comes equipped with 9V battery backup. This advanced smoke alarm functions as a stand-alone unit or in an interconnected system. The Kidde P12040 uses a photoelectric sensing technology that detects visible particles associated with smoldering fires sooner than ionization alarms. Ionization alarms detect invisible fire particles associated with flaming fires sooner than photoelectric alarms. Kidde recommends that both types of alarms be installed inside the home to protect against both types of fires. The smoke alarm can be installed on any standard single gang electrical box, up to a 4 octagon junction box. The electrical connection (to the alarm) shall be made with a plug-in connector. A maximum of 24 Kidde devices can be interconnected in a multiple station arrangement. The interconnect system must not exceed the NFPA (National Fire Protection Association) limit of 18 initiating devices, of which 12 can be smoke alarms. With 18 initiation devices (smoke, heat, CO, etc.), interconnected, it is still possible to interconnect 6 strobe lights and or relay modules. The unit shall provide optional tamper resistance that deters removal of the unit from the wall or ceiling. The alarm shall include a test button that will electronically simulate the presence of smoke and cause the unit to go into alarm. This sequence tests the units electronics, battery and horn to ensure proper operation. There is one red LED to indicate the alarm's current status and mode of operation. During the standby condition, the red LED will flash every 30-40 seconds to indicate the smoke alarm is operating properly. During the alarm condition, the red LED will flash rapidly (one flash per second). The rapid flashing and pulsating alarm will continue until the air is cleared from the products of combustion. The unit will also have one green LED to indicate the presence of power.
