{"product_id":"simplex-4098-9602-truealarm-photoelectric-detector","title":"Simplex 4098-9602 TrueAlarm Photoelectric Detector","description":"The Simplex 4098‑9602 TrueAlarm Photoelectric Detector integrates a high-performance photoelectric smoke sensor with a fast-response thermistor-based heat module, providing comprehensive multi-mode fire detection. Utilizing patented TrueAlarm sensitivity drift compensation, it continuously adjusts to environmental changes—dust, dirt, and aging—to maintain reliable smoke monitoring. The onboard heat sensor includes both fixed-temperature (135 °F\/57 °C) and rate-of-rise (\u0026gt;20 °F\/min when ambient ≥90 °F) detection. The TrueSense algorithm correlates smoke and thermal activity for intelligent, earlier fire response while minimizing false alarms. Mounting to a standard 4098 series base, the unit supports both 2-wire and 4-wire configurations, offers magnetic testing via LED indication, and is UL‑listed (UL 268), FM‑approved, CSFM‑listed, and NYC‑accepted. Its sleek, low-profile housing (4⅞″ diameter × 2″ height) features louvered intakes, ensuring efficient smoke entry and discreet aesthetics. Operating between 32 °F to 100 °F (0–38 °C), with 0–95% humidity, it’s engineered for diverse indoor commercial applications.","brand":"Simplex","offers":[{"title":"Default Title","offer_id":50804396884288,"sku":"4098-9602","price":80.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0707\/2274\/8736\/files\/4098_9602_0.jpg?v=1776336980","url":"https:\/\/store.greenwaveelectronics.com\/products\/simplex-4098-9602-truealarm-photoelectric-detector","provider":"Green Wave Electronics","version":"1.0","type":"link"}
