产品详情资料
当使用多个检测器时,它们应为在低电压(7至10V)下禁用的类型,以防止多次跳闸导致回路电流超过故障限值。c.当回路电源关闭5秒时,探测器应完全复位。4-17第4章安装说明MAN0546.PM6第01期,1999年3月5704F控制系统05704-M-5002 d。如果适当的报警限流电阻器与报警触点串联,则可连接具有无电压触点输出的检测器。应注意:a.大多数烟雾和热量探测器都内置有报警限流电阻器。然而,具有较高输出电流的检测器可能需要在环路电源线中的附加限制电阻器。b.现代手动呼叫点(MAC)通常内置报警电流设置电阻器,否则必须将620欧姆的典型报警电阻器与开关串联。c.功率较高的探测器,如许多火焰装置,需要通过3或4线连接单独供电。When multiple detectors are used they should be of a type that disable at low voltage (7 to 10V) to prevent multiple trips causing the loop current to exceed the fault limit. c. The detector should be completely reset when the loop power is switched off for five seconds. 4-17 CHAPTER 4 INSTALLATION INSTRUCTIONS MAN0546.PM6 Issue 01, March 99 5704F Control System 05704-M-5002 d. Detectors with voltage free contact outputs may be connected provided suitable alarm current limiting resistors are fitted in series with the alarm contact. It should be noted that: a. Most smoke and heat detectors have alarm current limiting resistors built-in. Detectors with higher output current may however require additional limiting resistors in the loop supply line. b. Modern manual call points (MAC) usually have alarm current setting resistors built-in, otherwise a typical alarm resistor of 620 ohms must be fitted in series with the switch. c. Higher powered detectors such as many flame units require a separate supply via a 3 or 4 wire connection.
