They are typically used during active firefighting conditions, during a fire alarm investigation, or during fire alarm system inspection and test. Operation requires a dedicated two-wire circuit, typically using twisted, shielded pair wiring (TSP) to minimize electrical noise pickup from adjacent wiring. Depending on the master control, up to 6 remote phones and the master can be in simultaneous use. Additional information can be found in Installation Instructions 579-226 and on data sheet S4100-0034 which describes 4100ES Master phone control operation.\u003c\/div\u003e\n\u003cp\u003e \u003c\/p\u003e","brand":"FIRE ALARM SYS","offers":[{"title":"Default Title","offer_id":51571376226624,"sku":"204105022962","price":151.38,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0831\/6466\/0032\/files\/2975-9053.webp?v=1772468510","url":"https:\/\/firealarmsys.com\/products\/simplex-2975-9053","provider":"FIRE ALARM SYS","version":"1.0","type":"link"}
