procedures.
• Detector/Transmitter Terminal Strips. Two detector/transmitter
terminal strip s are locate d near the bo ttom lef t corne r of the mai n circuit
board (see Figure 1). These two 9-point terminal strips facilitate wiring
connections to the detectors or transmitters. Although each terminal
strip can accommodate several different detector head models, only
one detector h ead at a time ma y be wi red per channel . The top term inal
strip is for channel 1 and the bottom terminal strip is for channel 2.
• Alarm Terminal Strip. The alarm terminal strip is located along the
bottom edge of the main circuit board (see Figure 1). This 21-point
terminal strips facilitates wiring connections to external alarm devices
(horn, strobe, etc.). Termin als are provided for individual channel as well
as common alarm relay contacts.
• Controller T e rminal Str ip. The 10-point controller terminal strip is near
the lower right edge of the main circuit board (see Figure 1). The

Relays
The Beacon 200 includes four channel relays (two per channel) and three
common relays. Both sets of relays are single-pole, double-thr ow (SPDT)
and are rated for 10 amps at 250 VAC (resistive).
NOTE: You can select normally energized (NE) or normally de-energized
(NDE) settings for ea ch channel in th e Channel Co ntrol and Setup
program. This section describes the default setting : normally deenergized.
The alarm 1 and alarm 2 common relays are factory-set as NDE
and the fail common relay is factory-set as NE. The alarm 1, alarm
2, and fail common relays’ NE/NDE settings are not useradjustable.
• Channel relays. The four channel relays are above the alarm terminal
strip (see Figure 1). These relays are dedicated to specific channels
and alarm levels.
For example, the channel 1, alarm 1 relay energizes if channel 1
recognizes an alarm 1 condition. Figure 3 below illustrates the
allocation of the channel relays

Chapter 5 for instructions.
For example, the al arm 1 common rela y energizes if either channel 1 or
channel 2 recognizes an alarm 1 condition.
Fuses
There are three fu ses that are used in t he Beacon 200 . T w o of them are AC
fuses and one of them is a DC fuse.
• AC Fuses. The two fuses located directly to the left of the controller
terminal strip are the AC fuses. They cut off the incoming AC power in
the event of a short circuit or other electric al fault which causes a high
current draw in the Beacon 200. They are housed in vertical fuse
holders and are held in the holder by a quarter turn cover. They are
labelled as F2 (top fuse) and F3 (bottom fuse) on the PCB silk-screen
and are rated at 3 A, 250 V.
• DC Fuse. The fuse located to the left of the power switch is the DC
fuse. It cuts off incoming DC power in the event of a short circuit or
other electrical fault which causes a high current draw in the Beacon
200. It is also housed in a vertical fuse holder and is held in the holder
by a quarter turn cover. It is labelled as F1 on the PCB silk-screen and
is rated at 6A, 250 V.
14 • Internal Description
Power Switch
The power switch is located above the relays and in between the AC and
DC fuses (see Figure 1). The power switch turns the incoming AC power
source on and off at the Beacon 200. When the switch is up, the power
switch is on.
NOTE: The DC power in put has no on/off switch and i s not af fected by the
position of this switch.
Power Supply
The power supply is mounted to the power supply mounting plate which is
located behind the display PCB. The p ower supply mounting plate is
mounted to the main PCB with fou r st a ndo ffs. The power supply receives
the AC input from the external power source and converts it to a DC
voltage that is usable by the Beacon 200 circuitry.
