EN: Solid-state plug-in ultraviolet flame amplifier for compatible Honeywell 7800 SERIES and R7140 relay modules. It works with C7027A, C7035A and C7044A Minipeeper UV detectors, provides a 0.0–5.0 VDC flame signal and has a 2/3-second flame-failure response time depending on the relay module.
AR: مضخم لهب إلكتروني صلب قابل للتوصيل يعمل بالأشعة فوق البنفسجية مع وحدات المرحل المتوافقة من Honeywell 7800 SERIES وR7140. يتوافق مع كواشف Minipeeper طراز C7027A وC7035A وC7044A، ويوفر إشارة لهب من 0.0 إلى 5.0 فولت تيار مستمر وزمن استجابة لفشل اللهب قدره 2 أو 3 ثوانٍ حسب وحدة المرحل.
The Honeywell R7849A1023 is a solid-state plug-in ultraviolet flame amplifier for compatible Honeywell 7800 SERIES burner controls and R7140 relay modules. It processes the ultraviolet signal generated by C7027A, C7035A or C7044A Minipeeper flame detectors and provides a 0.0–5.0 VDC flame-signal indication, with 1.25 VDC specified as the minimum acceptable steady signal.
The R7849A is the standard non-self-checking version and is identified by its purple ultraviolet label. The R7849A1023 configuration provides a flame-failure response time of 2.0 seconds with applicable CE relay modules or 3.0 seconds with applicable US relay modules. Built-in test jacks allow technicians to measure the flame signal during commissioning and maintenance.
The module operates from –40°C to +60°C and is intended for gas- and oil-fired burners that perform a controlled shutdown at least once every 24 hours. Detector selection, relay-module compatibility and flame-failure response time must be verified before installation.
