Dry Contact Alarm Outputs

Dry contact alarm outputs, located on

PCB1, are available regardless of any

additional monitoring method used. The

available dry contact alarm outputs are

listed in Table 1-4 and shown in Figure

1-5. Each contact can be wired as

normally open or normally closed.

NOTE: The alarm relay contacts are

labeled to represent their state with the

unit powered on and with no alarms

present.

To ensure proper alarm monitoring,

Flash Technology recommends

monitoring contacts that are open in an

alarm condition.

Flashhead Cable

Flash Technology cable (PN 4370000)

provides optimal system performance

while minimizing vulnerability to

Lightning and EMI (Electromagnetic

Interference). The cable is comprised of

two 8 AWG conductors with an overall

aluminized Mylar shield and drain. The

flashhead cable connects to TB2 in the

lower left of the SC 370 as shown in

Figure 2-4.

Wiring Procedure

1. Prepare the flashhead cable:

a. Remove 6 inches of the outer

jacket.

b. Remove the exposed aluminized

Mylar shield and any filler material

between conductors.

2. Loosen the dome nut of the ¾” cable

strain relief located in the bottom of

the enclosure near TB2 and insert the

cable.

3. Connect the three conductor flashhead

cable to terminal strip TB2 using a

non-flared flat tip screwdriver:

a. Connect the red wire to the

terminal labeled DC+.

b. Connect the black wire to the

terminal labeled DC-.

c. Connect the bare drain wire to the

terminal labeled GND.

4. Leaving slack in the flashhead cable,

tighten the dome nut so that the cable

is held securely in place.

NOTE: Install a 5’ service loop in the

cable near the controller.
