External Description This section describes the housing and all external components of the 12 VDC Beacon 200. For the purposes of this description, the housing door is considered the front of the monitor. Housing The 12 VDC Beacon 200’s fiberglass housing is weather- and corrosionresistant. It is suitable for installation where general purpose equipment is in use. The housing door is hinged on the left side and is secured by two latches on the right side.
Internal Description This section describes the internal components of the 12 VDC Beacon 200. Display Printed Circuit Board (PCB) The display PCB is mounted to the power supply mounting plate which is in turn mounted to the main PCB. The power supply mounting plate and main PCB are described below. The display PCB includes the display, the status lights, and the program buttons.
Status Lights The 12 VDC Beacon 200 includes four status lights that indicate the current status of the monitor. The status lights are to the left and right of the display (see Figure 2). • Pilot Light. The pilot light is on when the 12 VDC Beacon 200 is receiving incoming power. • Fail Light. The fail light turns on when the 12 VDC Beacon 200 is experiencing a fail condition. A fail condition can be caused by a failure within the 12 VDC Beacon 200 or detector head(s) wired to the 12 VDC Beacon 200.
Main PCB The main PCB is mounted inside the housing. The power supply mounting plate is mounted to the main PCB with four standoffs and the display PCB is mounted to the power supply mounting plate with four standoffs. The main PCB includes the terminal strips, relays, fuses, and power switch. Terminal Strips The 12 VDC Beacon 200 includes four terminal strips for external wiring connections. See “Wiring the 12 VDC Beacon 200” on page 13 for detailed wiring procedures.
• DC In Terminal Strip. The DC in terminal strip is a 3-point terminal strip located above the controller terminal strip (see Figure 1). It facilitates wiring from a 12 VDC power source. Table 4 lists the function of each terminal.
NOTE: The alarm 2 channel relays may be set to operate as individual channel fail relays. See “Configure Channel Settings Menu” on page 30 for instructions. • Common relays. The three common relays, alarm 1, alarm 2, and fail, are to the left of the controller terminal strip (see Figure 1). These relays are common for both channels. For example, the alarm 1 common relay energizes if either channel 1 or channel 2 recognizes an alarm 1 condition.
