It detects rising heat—135°F and above—providing a dedicated warning in spaces where smoke detectors may not be ideal, such as kitchens, garages, or attics. This differential sensing helps you notice dangerous temperatures before they become visible smoke.\u003c\/p\u003e\n\u003ch3\u003eWhy this heat detector can fit your home safety plan\u003c\/h3\u003e\n\u003cp\u003eHeat alarms like the HD135F complement traditional smoke detectors by focusing on rapid temperature changes rather than smoke. When used in tandem, you may experience fewer nuisance alerts while still receiving an early warning in high-heat scenarios. The unit connects quickly to your existing system and can be part of a broader, monitored setup.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e135°F temperature threshold with an 85 dB alarm to alert occupants promptly\u003c\/li\u003e\n  \u003cli\u003e120V powered with a 9-volt alkaline battery backup for operation during power outages\u003c\/li\u003e\n  \u003cli\u003eQuick-connect power harness for fast, tool-light installation\u003c\/li\u003e\n  \u003cli\u003eTwo LEDs show status: green for AC power; red for normal operation and alarm indication\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eKey features at a glance\u003c\/h3\u003e\n\u003cp\u003eThe heat detector can function as a single unit or interconnect with up to 24 Kidde devices in a multi-station arrangement, while staying within NFPA limits. Up to 18 initiation devices (smoke, heat, CO) can be interconnected in one system, with the option to add up to 6 strobe lights or relay modules. A tamper-resist pin adds an extra layer of security against tampering.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eInterconnection capability: connect up to 18 initiating devices and 24 total Kidde devices\u003c\/li\u003e\n  \u003cli\u003eNFPA-compliant interconnect limits help you plan a safe, compliant network\u003c\/li\u003e\n  \u003cli\u003eTamper-resist pin helps deter tampering or theft\u003c\/li\u003e\n  \u003cli\u003eUL certified with a 5-year limited warranty for peace of mind\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eOperational indicators and usage tips\u003c\/h3\u003e\n\u003cp\u003eTwo LEDs provide clear status signals. A green LED remains on when AC power is present. A red LED flashes every 30–40 seconds to indicate normal operation, and it flashes rapidly when the detector is sounding. The built‑in Test-Hush button makes testing straightforward and can help silence false alarms caused by cooking steam, dust, or humidity.\u003c\/p\u003e\n\u003cp\u003eDesigned for places where heat is the primary concern, this detector complements smoke alarms in a home safety plan. It’s ideal for garages and other areas where high temperatures might occur without smoke, offering a practical layer of early warning while keeping nuisance alerts to a minimum. UL certified, Kidde backs the unit with confidence through a 5-year limited warranty.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What spaces is the Kidde HD135F heat detector best suited for?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Ideal for garages and other areas where smoke detectors may false alarm, offering temperature-based warning.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Can the HD135F be interconnected with other alarms?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Yes.
