DIP 4, DIP 5, DIP 6, and DIP 7:

Remote Mode Trigger Settings

DIP Switch position 4 is used to deﬁne how the CN-1800S will implement

its FORCE OFF feature. FORCE OFF is a safety feature that is designed to

cut AC power to all outlets instantaneously. Many municipalities require

this feature as a means of disabling equipment in the presence of ﬁre

or alarm. The FORCE OFF inputs are the two uppermost poles on Barrier

Strip 3. The FORCE OFF inputs can be used with a momentary or main-

tained dry contact in either a Normally Open or Normally Closed state.

The factory default position is DIP 4 ON or UP, or (NO) Normally Open.

In this conﬁguration, the FORCE OFF will be triggered when the FORCE

OFF pins are shorted. If DIP Switch position #4 is on (DIP 4 Off or DOWN)

the FORCE OFF pins must remain shorted for normal operation. In this

conﬁguration, the FORCE OFF will be triggered when the short between

the FORCE OFF pins is removed.

If a FORCE OFF occurs, the power to all outputs will be immediately dis-

abled and the DELAY LEDs will blink together. To recover from a FORCE

OFF condition, the CN-1800S or all units in the sequencing chain must

be sequenced off locally, via the Key Switch or Start Sequence pushbut-

ton. Once reset, operations will resume normally. DIP 4 has priority over

Maintained / Momentary

Sets contact closure preference for either Maintained or Momentary

switches. NOTE: Momentary mode overrides DIP 5 and 6.

DIP 5, DIP 6, and DIP 7 settings. Information found under the following

sections DIP 5, DIP 6, and DIP 7 explain typical remote switch operations.

The use of DIP 4 may or may not be a consideration at every install, yet it

may be vital with regards to safety compliance. The FORCE OFF feature is

always active, despite the fact sometimes it is in a forgotten state of op-

eration. And again, the DIP 4 factory-set position is Up, or (NO) Normally

Open; in order not to disrupt other sequencer functions when emergency

systems are not required.

DIP 5 (+12V, ON OFF) and DIP 6 (GND ON) are used in special situations,

where the standard Contractor Series factory-set remote options are not

preferred. For instance, where a newly remodeled location has an existing

remote key switch different from a Furman remote key switch design; the

mechanics of key switch are the reverse. Yet it would be advantageous

to use the existing key switch, since many personnel already have keys.

DIP 5 (+12V, ON OFF) and DIP 6 (GND ON) could possibly address such

situations. Please feel free to contact Furman, if further assistance is

necessary.

DIP 7 is used to set the remote switching preference. The CN-1800S

can be set to a Maintained Mode (DIP 7 OFF or DOWN) or a Momentary

Mode (DIP 7 ON or UP) dependent upon the chosen method of remote

switching. A Maintained switch method stays open until switched, and

then remains closed until switched again (such as toggle switches, e.g.

Furman RS-1 key lock switch).The Momentary switch method is normally

open and stays closed only as long as the button is depressed (such

as pushbutton switches, similar to the Furman RS-2 security switch).

Momentary Mode does offer an advantage over Maintained Mode when

multiple remote switching locations are desired. Due to technical ﬂexibil-

ity, Momentary switching easily adapts when implemented with more than

one remote switch. However, it is often thought Maintained switching is

more stable, truly shunting control voltages when actuated. DIP 5 and DIP

6 offer additional methods of applying Maintained switching. Regardless

of which switching method is chosen, when changing DIP 4, DIP 5, DIP 6,

or DIP 7, it is required to reset the AC power to the unit.

The CN-1800S has one Momentary Mode of operation (DIP 7 ON or UP),

which is also compatible with Furman Legacy products. As suggested,

when more than one remote switching location is required, momentary

switches offer an advantage. In addition to this beneﬁt, multiple Primary

units set to Momentary Mode can be interfaced together using the

Remote Pole contacts +12V, REM and GND, wired in parallel pole to

pole. No one unit is considered the Primary Unit, yet any unit can act as

one. The multiple units’ delay cycle would initiate at the same time, in

combination with each other; in other words, the units would all start at

once and all initiate a cycle down at once, once any Momentary switch

(button) is pushed (including Remote Momentary switches). As men-

tioned, multiple momentary remote contacts should be used if more than

one remote power up location is desired. If units by chance, drop out of

sync, simply press and hold down the Start Sequence button for several

seconds to re-sync. The wiring of multiple Primary Units in parallel via the

Remote Pole contacts is a Furman legacy operation.
