It is listed to ANSI/UL 217 and ANSI/UL 2034 and incorporates a 10-year end-of-life indicator.

Gentex PL1AS PLACE Any Space Smart Smoke and Carbon Monoxide Alarm

The Gentex PL1AS (918-0022-002) is a hardwired combination smoke and carbon monoxide alarm integrating five residential safety and monitoring functions in one device. Part of the Gentex PLACE Any Space smart alarm family, this white ceiling- or wall-mounted unit combines photoelectric smoke detection, electrochemical carbon monoxide sensing, radar-based motion detection, temperature monitoring, and humidity monitoring to provide comprehensive awareness of conditions inside the home. Its primary smoke and CO sensing functions provide local life safety notification, while integrated Wi-Fi connectivity enables additional monitoring through the PLACE mobile application. Designed for single-family homes, apartments, bedrooms, hallways, and other eligible residential spaces, the PL1AS provides a modern alternative to conventional combination smoke and CO alarms. The device uses 120 VAC, 60 Hz hardwired electrical power with replaceable 3V lithium battery backup, helping maintain essential alarm operation during interruptions in household electrical service.

The Gentex PL1AS incorporates photoelectric smoke sensing and carbon monoxide detection with a 520 Hz low-frequency audible warning system, designed to provide recognizable emergency notification while improving alarm effectiveness for occupants who may have difficulty responding to conventional higher-frequency alarms. The low-frequency sounder meets applicable ANSI/UL 217 audible output requirements, while localized voice announcements identify smoke and carbon monoxide alarm conditions to help residents understand the nature of an emergency. A multicolor illuminated ring provides visual status feedback for alarm, testing, pairing, and device configuration functions. The PL1AS also features interconnection capability with compatible Gentex PLACE alarms, allowing interconnected devices to provide coordinated notification when a participating alarm detects a hazardous condition. Manufacturer instructions permit interconnection of up to 18 compatible alarms, including a maximum of 12 smoke alarms, with additional wiring and branch-circuit restrictions. Its built-in Test/Silence button supports local operational testing and temporary alarm hushing when conditions permit.

The PLACE Any Space platform incorporates Wi-Fi connectivity and mobile application integration for remote monitoring, event notifications, and device management. Through the PLACE application for compatible iOS and Android devices, users can review smoke and CO alarm notifications, monitor ambient temperature and humidity, configure motion detection notifications, and initiate supported remote testing functions. The integrated radar-based motion sensor detects activity within the monitored space and provides app-based notifications with configurable sensitivity settings. A built-in motion-activated smart nightlight offers adjustable color and brightness, providing illumination in bedrooms, hallways, and other residential areas without requiring a separate nightlight fixture. The device also supports temperature and humidity monitoring with historical reporting through the PLACE application, enabling homeowners to identify changes in room conditions. Bluetooth pairing simplifies initial setup, while the wireless network connection supports cloud-enabled monitoring and smartphone notifications. These connected features supplement the alarm's primary smoke and carbon monoxide warning functions rather than replacing local audible notification.

The Gentex PL1AS operates from 120 VAC at 60 Hz with a maximum current draw of 0.1 amp and includes two replaceable Energizer Ultimate Lithium AA (L91) batteries for emergency backup. The manufacturer specifies an indoor operating temperature range of 40 F to 100 F (4.4 C to 37.8 C), making the alarm suitable for conditioned residential environments. Its supplied mounting bracket, quick-disconnect wiring harness, wire connectors, mounting screws, and protective dust cover support installation on compatible standard electrical junction boxes. The hardwired interconnection interface allows connection to approved Gentex PLACE alarms, while its battery backup continues providing essential protection during a power outage when the batteries are properly installed. The PL1AS features a 10-year end-of-life indicator that notifies occupants when the complete alarm must be replaced. The unit is listed to ANSI/UL 217, 9th Edition, for smoke alarms and ANSI/UL 2034, 4th Edition, for carbon monoxide alarms, with applicable FCC Part 15 compliance. Unlike the PLACE Kitchen PL1K, which adds natural gas detection, or the PLACE Nursery PL1N, which incorporates additional room monitoring capabilities, the PL1AS Any Space model provides the core smoke, CO, motion, temperature, humidity, and smart nightlight features for general residential installation. Combining low-frequency audible alerts, hardwired power, lithium battery backup, interconnected signaling, and mobile monitoring, the Gentex PL1AS delivers an integrated residential life safety and home awareness solution.
