§ FAQ

What is the egress light feature on the P4010LDCS-W?

The egress light is a built-in LED safety light that automatically activates when the alarm sounds. It provides illumination in dark hallways and bedrooms to help occupants navigate to exits safely during an emergency, particularly at night.

How is the P4010LDCS-W different from the P4010DCS-W?

The P4010LDCS-W is identical to the P4010DCS-W but adds a built-in egress safety light. If you are installing in a hallway or bedroom where emergency lighting would be beneficial, the P4010LDCS-W is the better choice.

Does the P4010LDCS-W require hardwiring?

No. The P4010LDCS-W is fully battery-powered with a 10-year sealed lithium battery. Both the alarm operation and wireless RF interconnect run on the sealed battery with no electrical wiring required.

How many alarms can be networked with the P4010LDCS-W?

Up to 24 compatible Kidde Wire-Free devices can be interconnected in a single supervised RF network, ensuring all alarms sound when one detects smoke across multiple floors and rooms.

Is the sensor photoelectric or ionization?

The P4010LDCS-W uses a photoelectric sensor, which is effective for detecting slow-smoldering fires and produces fewer nuisance alarms from cooking and steam compared to ionization-only alarms.
