This removed the need to change all the fittings as the alarm was exactly the same, and would suggest that it is a reliable and popular model. This particular alarm came as a 2 pack which also made it very economical. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.jp/products/137109105-2-x-st-622t-10-year-thermally-enhanced-optical-smoke](https://www.desertcart.jp/products/137109105-2-x-st-622t-10-year-thermally-enhanced-optical-smoke) --- *Product available on Desertcart Japan* *Store origin: JP* *Last updated: 2026-07-18*
