D1000 Installation and Service Manual 20
Home LAB-110073 Rev. 3
Do not allow slack wire rope cable to collect above the hood. (See Figure 14.5 MPK
Front Plate)
MANUAL PULL STATION (MPK) INSTALLATION
CABLE TRAVELING/DISCHARGE MECHANICS
Positioning the Hood
Lowering the hood form its Normal Operating Position (NOP) to 45⁰ Maintenance Position (MP)
The stainless-steel rope travels 3.5 inches when lowering the hood from NOP to 45⁰ MP
In order to ease the force required to manually activate the MPK, a momentum of force is suggested
when pulling the cable at the MPK station.
Manual Activation
Per NFPA 96 Code:
o Force
Shall not require more than 178N (40lbs.) of force to activate
Our system is tested at 15.6 lbs.
o Travel Distance
Movement not to exceed 356 MM (14 inches)
Since the minimum traveling distance of the SS cable is 3.5 inches and the maximum per code is
14 inches, we recommend 7-10 inches of extra cable slack
o Cable Slack Location
The extra cable needs to be located at the MPK Station coiled inside of the junction box.
NFPA 96 SECTION 10.5
NOTE: The D1000 hood systems only ship with 25’ of cable; longer sections are not sold;
DFP recommends following installation requirements found in NFPA96 Section 10.5

10.5 Manual Activation
10.5.1 A readily accessible means for manual activation shall be located between 1067 mm. and 1219
mm (42 in. and 48 in.) above the floor, be accessible in the event of a fire, be located in a path of
egress, and clearly identify the hazard protected.
10.5.1.1 At least one manual actuation device shall be located a minimum of 3m (10ft.) and a
maximum of 6 m (20 ft.) from the protected hood exhaust system(s) within a path of egress or at an
alternative location acceptable to the AHJ.
10.5.1.2 Manual activation using a cable-operating pull station shall not require more than 178 N (40
lb.) of force, with a pull movement not to exceed 356 mm. (14 in.) to activate the automatic fire-
extinguishing equipment.
10.5.2 The automatic and manual means of system activation external to the control head or releasing
device shall be separate and independent of each other so that failure of one will not impair the
operation of the other except as permitted by 10.5.3.
