Energetic Safety Systems
Ignition Safety Devices
Excelitas has developed a MIL-STD-1901A-compliant initiator that
has the same form-factor as existing older-style, non-compliant low
voltage initiators. Excelitas’ initiators can be directly inserted into
existing systems.
Designed for Safety with
Command-to-Launch and
Launch Environment Sensing
Excelitas specializes in the design and manufacture of MIL-STD-1901A-
compliant rocket motor ignition safety devices (ISDs). ISDs are devices that light
both launch and flight motor initiators, whose purpose is to prevent unintended
functioning of the rocket or missile motor through interruption of the
pyrotechnic train or control of the energy required to arm the ISD and function
the initiator. Our designs include Through-Bulkhead Initiators that work in-line
with the detonator to provide highly-reliable transfer of pyrotechnic energy,
while isolating the ISD from the rocket motor heat and combustion effects.
Excelitas also design ISDs utilizing either a single igniter or multiple igniters
in one package, as necessary to meet customer requirements.
Applications
• Tactical missiles
• Strategic missiles
• Missile defense systems
• Surface-to-surface rockets
• Air-to-surface rockets

Energetic Safety Systems
Ignition Safety Devices (ISDs)
Excelitas manufactures ISDs for
both first- and later-stage rocket
motors. When used in a first-stage
rocket motor, the ISD is armed and
fired by robust command-to-launch
signals. In a second or later-stage
rocket motor, the ISD is aimed
and fired by robust launch
environment sensing.
Excelitas is the only ISD
supplier with in-house
energetic component design
and manufacturing capabilities
offered through our Blue Chip ®
Detonators. Excelitas’ Blue Chip ®
Detonator is the only detonator
qualified for high-shock
environments.

Product Performance and Reliability
MIL-STD-1901A-Compliant Design
MIL-STD-1901A requires the use of an ISD device for all new rocket motor designs.
Excelitas ISDs comply with MIL-STD-1901A and all other pertinent safety standards
through the use of redundant safety circuitry. This includes two independent and
redundant detection circuits for launch environment sensing. For command-to-launch
systems, Excelitas ISDs are designed to ensure that a robust sequence of events occurs
prior to the ISD’s arming and firing of the initiator.
Our broad portfolio of Fuze Board-approved circuitry streamlines new product
development and Fuze Board approval while minimizing the cost and time associated
with technology development and qualification.
Excelitas ISDs employ MIL-STD-1901A compliant arming delay timers constructed of
dissimilar technologies, reducing the probability of common mode failures, shortening
development schedule, and substantially reducing the risk of Fuze Board approval for
new designs. Our arming delay timer designs are set specifically to allow the weapon
system to reach a safe distance from the launch platform, ensuring “safe separation
distance” prior to arming the device.
Excelitas manufactures ISDs using both complex logic devices (microcontrollers
and FPGAs) and discrete implementations. Complex logic devices provide ease of
configurability while discrete implementations maximize reliability and can shorten
the duration of the development schedule by eliminating software development and
approval by the Fuze Board. Excelitas’ use of complex logic devices is in compliance
with the Fuze Engineering Standardization Working Group (FESWG) requirements
for the use of logic devices.
Mechanical Packaging and Reliability
Excelitas designs ISD packaging to address a variety of ruggedization requirements such
as miniaturized devices to enhance reliability of the ISD during high-g gun launches.
Through years of ISD design and testing, Excelitas has developed proprietary methods
of protecting electronics from potentially degrading exposure to heat, humidity,
vibration, etc. Application-specific potting materials or conformal coatings are used
to seal the electronics from the external environment and also provide mitigation
against tin whisker growth. These techniques ensure that our ISDs are reliable for
use after long-term storage of the weapon system.
MIL-DTL-23659 Qualified Blue Chip ® Detonators
Excelitas manufactures many different types of detonators, allowing us to select the
right device for varying environmental conditions. Options range from low-energy Blue
Chip ® detonators to dual-load and shock-hardened detonators. Excelitas recrystallizes,
processes, and presses our own explosive powders, resulting in improved reliability and
consistent performance for each energetic device.

Ignition Safety Devices (ISDs)
Electrical Interface
Excelitas ISDs utilize a wide range of electrical interfaces. Basic designs include
connectors mounted on the surface of the package or external cables routed
to the next subassembly.
Available with Shock-hardened Data Recorder
Excelitas ISDs can be made with or without a tiny, on-board 22-channel
shock-hardened data recorder, or Informant Nano Recorder.
Extensive In-House Test Capabilities
Excelitas has extensive in-house capabilities for testing vibration, drop shock,
thermal shock, humidity, extreme temperatures, and long-term aging. Our
comprehensive environmental test facility ensures compliance to customer
specifications and military standards. Most of our products also have a dedicated
factory test connector, which brings all significant signals out to our Excelitas
Gen4 test system, allowing every feature of the ISD to be rigorously tested.
All of our products employ Excelitas’ patented removable detonator feature,
which allows an inert detonator to be installed during factory testing, allowing
the ISD to be fully functioned during factory testing, including arming and firing.
Threshold testing is performed for each Excelitas ISD design to determine the
precise voltage, capacitance and inductance required to provide reliable
detonation. Excelitas has comprehensive explosive testing facilities and industry
recognized subject matter experts who ensure that each ISD design reliably
initiates the explosive train, including margin and over worst-case conditions.
Lot and Serialization Control
Many Excelitas safety devices contain an EEPROM that holds information
about the serial number, manufacturing date, customer part number, etc.
The ISD can be queried at any time to retrieve this data.
About The Informant
The Informant can help reduce
the duration and cost of failure
investigations when a test does
not go according to plan.
What is the “Gen4” Electronics
Test System?
Excelitas has developed and implemented
a fourth generation electronics test
system for ESAFs and ISDs. It can be
used for product development, factory
testing, and field testing.
Key benefits of Excelitas’ “Gen4”
Test System include: real-time tactical
operation of the unit under test; a
common hardware and software
architecture that can be applied to a
wide variety of ESAFs and ISDs to
dramatically reduce development time
and costs; scalability to fit program
volume requirements; and data storage
via an SQL database for quick retrieval
and analysis.
