The system requires a 10-minute warm-up
prior to operation. To ensure automatic
system operation when required, be sure
the set is operational and all caution and
indicator lights are out prior to entering
POWER control switch ON
Warm-up light ON, allow 10 minutes for
warm-up. At the end of warm-up period, the warm-up
light will be shut off.
Status switch Push for standby operation
or release to commence automatic protection.
CM JAM caution light Check OUT.
CM INOP caution light Check OUT. If cau-
tion light is on, the set has malfunctioned and the helicop-
ter is without countermeasure protection.
STATUS switch Push for standby operation
when countermeasures protection temporarily is not re-
quired and/or accidental flare launch is a danger (LZ/PZ
POWER switch OFF when countermea-
sures protection is no longer required (EOM).
If countermeasures set has been off for
less than 5 minutes and further operation
is required, the warmup indicator light
may go out immediately (or within some
interval less than the normal 10 minute
warmup period) after the power switch is
set to on. If this occurs, it is mandatory
that the system be operated in STBY for at
least 1 minute. Failure to observe this re-
quirement can result in a false alarm
(launch) and/or transmitting frequency in-
stability resulting in interference with oth-
er countermeasures sets.
4-1-8. Flare Dispenser M-130.
The Flare Dispenser M-130 (fig. 4-1-6) will dispense up
to 30 decoy flares as a countermeasure to infrared seek-
ing missiles. The externally mounted dispenser is con-
trolled by a DISP CONT control panel on the console and
six firing switches. Two cockpit firing switches are pro-
vided, one on each pilots control stick grip. Four hand-
held crewmember firing switches are installed in the cab-
in area. Flares can also be automatically fired by firing
commands from the countermeasure set (AN/ALQ-156)
if the set detects a missile approach. A timer in the cabin
provides a 2.5 second delay between firing pulses re-
gardless of firing switch position. A ground safety relay,
controlled by a landing gear proximity and a safety pin
manually installed into the dispenser, prevents firing
flares when the helicopter is on the ground. The system
is powered by the No. 1 DC bus through the CHAFF
circuit breaker on the No. 1 PDP.
Although the control panel, dispenser, and
circuit breaker are marked CHAFF or have
CHAFF (C) selector positions, chaff cannot
be dispensed at this installation.
4-1-9. Dispenser Control Panel.
The DISP CONT panel is installed in the center console. The
panel contains the ARM SAFE switch, ARM indicator light,
RIPPLE FIRE switch, FLARE counter, and counter setting
knob. The panel also includes a MAN-PGRM switch and
CHAFF counter, which are not used in this installation.
4-1-10. Dispenser Status Panel.
The dispenser status panel (fig. 4-1-6) provides an indication
of safety relay operation and system arming. It also allows
the landing gear safety switch to be bypassed for ground
testing of the dispenser system. The panel is on the left side
of the cabin at sta 534.
4-1-11. Controls and Function, Flare Dispenser Sys-
tem (M-130) (fig. 4-1-6)
At SAFE, the system is not
powered. At ARM, the sys-
tem is powered, provided
the safety pin is removed
from the electronic module
and the ground safety relay
is energized. (Helicopter air-
borne or remote bypass
switch on remote test panel
is at BYPASS.)
