Product Overview
NEC Hazardous-Location Classifications
The Siemens ─ Fire Safety Intrinsically-Safe Zone
Module (Model ZS-30) is designed for use with
devices that are located in hazardous areas, as part
of a System 3 fire-alarm control panel (FACP).
Class I: Class I locations are those in which flammable
gases or vapors either are or may be present in the air in
quantities sufficient to produce explosive or ignitable
mixtures.
Class II: Class II locations are those that are hazardous
because of the presence of combustible dust.
Class III: Class III locations are those that are hazardous
because of the presence of easily ignitable fibers or
flyings, but in which such fibers or flyings are not likely to
be suspended in the air in quantities sufficient to produce
ignitable mixtures.
Division 1: A Division 1 location is where either:
Model ZS-30 is Factory Mutual (FM) Approved for
use in:
9 Class I, Division I ─ Groups A, B, C and D hazards
[when used with the Model DI-3IS ionization
smoke detector]
9 Class I, II, III, Division I ─ Groups A, B, C, D, E, F,
and G hazards [when used with the Model S121 or
Model S122 flame detectors]
Model ZS-30 utilizes a diode shunt barrier, located
outside of the hazard area to limit the energy within
the hazard area, in the event of equipment failures.
Model ZS-30 is located outside of the hazardous
area.
a.) hazardous concentrations of flammable gases or vapors exist
continuously, intermittently, or periodically under normal
operating conditions
b.) hazardous concentrations of such gases or vapors may exist
frequently because of repair or maintenance operations or
because of leakage
c.) breakdown or faulty operation of equipment or process that
might release hazardous concentrations of flammable gases or
vapors occurs and might also cause simultaneous failure of
electric equipment

Specifications
─ (continued)
Group A: Group A atmospheres contain acetylene.
Group B: Group B atmospheres contain chemicals such
as: butadiene, hydrogen ethylene oxide (or gases /
vapors of equivalent hazard to hydrogen such as:
manufactured gas), or propylene oxide.
Group C: Group C atmospheres contain chemicals such
as: acetaldehyde, cyclopropane, diethyl ether, ethylene,
isoprene, or unsymmetrical dimethyl hydrazine (UDMH).
Group D: Group D atmospheres contain chemicals such
as: acetone, acrylonitrile, alcohols, ammonia, benzene,
benzol, butane, ethylene dichloride, gasoline, hexane,
lacquer-solvent vapors, naphtha, natural gas, propane,
propylene, styrene, vinyl acetate, vinyl chloride, or
xylenes.
Group E: Atmospheres containing combustible metal
dusts, regardless of resistivity or other combustible dusts
of similarly hazardous characteristics, having resistivity of
less than 105 ohm / centimeter.
Group F: Atmospheres containing carbon-black,
charcoal, coal, or coke dusts that have more than eight
(8) percent total.
Group G: Atmospheres containing combustible dusts
having resistivity of 105 ohm / centimeter or greater.
Used as a functioning component with a System 3
FACP, The Siemens ─ Fire Safety Intrinsically-Safe Zone
Module (Model ZS-30) shall be used with devices that
are located in hazardous areas, categorized by the
following:
The heat and smoke detectors located in the Class I,
Division 1 areas are connected via a (2) two-wire, Style B
(Class B) circuit to the diode shunt barrier located in a
non-hazardous area. Model ZS-30 is then wired to the
diode shunt barrier. Under normal operating conditions,
the voltage and current used in the hazardous area are at
levels known to be safe for intrinsically safe equipment.
The diode shunt barrier prevents excessive voltage and
current from reaching the hazardous area, due to any
combination of two independent faults and field wiring
failures.
Each detection circuit will either accommodate 10 Model
DI-31S ionization detectors, or five (5) Model S121 or
Model S122 infrared flame detectors ─ as well as any
number of non-energy storing contact devices, such as
thermal detectors or manual stations.
Each device located in the hazardous areas must have a
FM intrinsically safe label on it or it must be a direct
shorting-type device not containing any other
components. Examples of detection devices which may
be located in hazardous areas are Models:

detector]
9 Class I, II, III, Division I ─ Groups A, B, C, D, E, F, and

Model ZS-30 shall use a diode shunt barrier, located
outside of the hazard area to limit the energy within the
hazard area, in the event of equipment failures.
The module shall be system interconnected with a 10pin plug-and-harness assembly, and shall be approved
by Factory Mutual (FM) for this use.
The Detection Circuit shall provide Style B (Class B)
supervision ─ capable of operating ionization detectors
and any number of non-energy storing contact devices.
Upon operation of any single detector, the system shall
lock into alarm mode and the red LED on the face of the
module shall illuminate. A yellow trouble-event LED
shall illuminate should a break occur in the detection
circuit. Both LEDs shall be lamp tested from the System
3 FACP. The module shall be placement supervised.
