Specifications of these devices and all FireLlte products are <br /> Maximum IDC wiring resistance:1,500 ohms. available from Firel-ite. <br /> Maximum IDC Voltage:11 Volts. <br /> Maximum IDC Current:240 pA <br /> EOL resistance:47K ohms. <br /> Maximum SLC Wiring resistance:40 Ohms. <br /> Temperature range:320 to 120°F(00 to 4WC). <br /> Humidity range:10%to 93%(non-condensing). <br /> Dimensions: 4.5" (11.43 cm) high x 4" (10.16 cm) wide x <br /> 2.125"(5.398 cm)deep. <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"2T'. <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 /> QCAUTION: <br /> Avoid duplicating addresses on the system. <br /> Installation <br /> MMF-300(A), MMF-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,and <br /> 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.
