Manual,PN 51309. <br /> Maximum current draw:6.4 mA(LED on). <br /> Architects'/Engineers' Specifications <br /> Average operating current:750 NA(LED flashing). <br /> Maximum IDC wiring resistance: 1,500 Ohms. Specifications of these devices and all FireLite products are <br /> available from FireLite. <br /> Maximum IDC Voltage: 11 Volts. <br /> Maximum IDC Current:240 NA <br /> EOL resistance:47K Ohms. <br /> Temperature range:32°to 120°F(0°to 49°C). <br /> Humidity range: 10%to 93%(non-condensing). <br /> Dimensions: 4.5" (11.43 cm) high x 4" (10.16 cm) wide x <br /> 1.25" (3.175 cm) deep. Mounts to a 4" (10.16 cm) square x <br /> 2.125"(5.398 cm)deep box. <br /> MDF-300(A)AUTOMATIC ADDRESSING <br /> The MDF-300(A) automatically assigns itself to two address- <br /> able points, starting with the original address. For example, if <br /> the MDF-300(A) is set to address "26", then it will automati- <br /> cally assign itself to addresses"26"and"27". <br /> NOTE: "Ones"addresses on the MDF-300(A) are 0, 2, 4, 6, or 8 <br /> only. Terminals 6 and 7 use the first address,and terminals 8 and <br /> 9 use the second address. <br /> CAUTION: <br /> Avoid duplicating addresses on the system. <br /> Installation <br /> MMF-300(A), MM'F-302(A), and MDF-300(A) modules mount <br /> directly to a standard 4"(10.16 cm)square,2.125"(5.398 cm) <br /> deep, electrical box. They may also be mounted to the <br /> SMB500 surface-mount box. Mounting hardware and installa- <br /> tion instructions are provided with each module. All wiring <br /> must conform to applicable local codes,ordinances,and regu- <br /> lations. These modules are intended for power-limited wiring <br /> only. <br /> The MMF-301(A)module is intended to be wired and mounted <br /> without rigid connections inside a standard electrical box. All <br /> wiring must conform to applicable local codes, ordinances, <br /> and regulations. <br /> Agency Listings and Approvals <br /> In some cases, certain modules may not be listed by certain <br /> approval agencies, or listing may be in process.
