Supervised Input - Honeywell SEC-H-600 Installation Instructions Manual

SEC-H-600 SECURITY CONTROLLER

Supervised Input

The SEC-H-600 controller has six (6) supervised inputs, located on three 3-position connectors next to the DB-9 connector (see
Figure 9 below). Under each connector, terminals are labeled SIn, GND, SIn, for example: SI3, GND, SI4. This means when
wiring, two conductors are typically landed to each GND terminal.
NOTE: Supervised inputs SI1 through SI4 are reserved for Door 1 and 2 usage. Supervised inputs SI5 and SI6 are available for
general usage. For more details, see "Door Terminal Associations," page 15.
Each supervised input can monitor dry contacts, either normally-open (N.O.) or normally-closed (N.C.). One End-of-Line Resistor
Pack is required at the monitored contacts for each input, for proper operation. Figure 9 shows wiring of supervised inputs S1 and
SI2, which are reserved for Door 1 usage.

End-of-Line Resistor Pack
You must install an end-of-line (EOL) resistor pack at the monitored device for proper operation of each input. Six (6) EOL resistor
packs are shipped with each SEC-H-600 controller. Each resistor pack has four leads:
• New style (shipping soon): One red, one white, two black leads. Wire as shown in Figure 9 above.
• Old style: Two white, two black leads. Wire black leads across contacts, and wire the white lead shown internally connected to
the black lead (common) to the "GND" input, and the other white lead to the "SIn" input. See the detail in lower right of
Figure 9.
Install each EOL resistor pack as close as possible to the actual monitored switch/contacts.
