1.3 QUALITY ASSURANCE
A.
The manufacturer shall submit a written statement indicating that a factory authorized
representative inspected the installation. The installing contractor shall submit a checkout
memorandum to the manufacturer indicating the date the equipment was placed into
service and the actual method of installation. Submit three copies of each to the A/E.

1.4 WARRANTY
A.
The SPD and supporting components shall be guaranteed by the manufacturer to be free
of defects in material and workmanship for a period of 5 years from the date of substantial
completion of service and activation of the system to which the SPD is attached.
B.
An SPD that shows evidence of failure or incorrect operation during the warranty period
shall be repaired or replaced, including labor and materials, at no expense to M-DCPS.
Since "Acts of Nature" or similar statements typically include the threat of lightning to
which the SPD shall be exposed, any such clause limiting warranty responsibility in the
general conditions of this specification shall not apply to this warranty. The warranty shall
cover the entire device, not just the modules.
C. The installation of SPDs in or on electrical distribution equipment shall in no way
compromise or violate equipment listing, labeling, or warranty of the distribution
equipment.
1.5 SUBMITTALS
A.
Submittals shall include, but not be limited to, the following information:
1.

6.
Data for each SPD type indicating conductor sizes, conductor types, connection
configuration and lead lengths.
Manufacturer’s certified test data indicating the ability of each SPD to meet or exceed
requirements of this specification.
Drawings, with dimensions, indicating SPD mounting arrangement and lead length
configuration, and mounting arrangement of any optional remote diagnostic
equipment and assemblies.
List and detail protection systems such as fuses, disconnecting means and protective
materials.
SPD wiring, bonding and grounding connections shall be indicated on the wiring
diagrams for each system. Include installation details demonstrating mechanical and
electrical connections to equipment to be protected.
If requested, a sample of each SPD type shall be submitted for use in testing and
evaluation.

SPDs shall be listed according to UL – Third Edition 1449 Standard for Safety,
Transient Voltage Surge Suppressors, and UL 1283, Electromagnetic Interference
Filters.
Services entrance equipment SPD’s shall be labeled as Type 1 with 10 modes of
protection: 3-modes (Line-to-line) 3-modes (Line-to-Ground), 3-modes (Line-toNeutral), and 1-mode (Neutral-to-Ground) for a 3-phase, 4-Wire plus ground voltage
system. (Line-to-Neutral-to-Ground is not an acceptable substitute for Line-toGround).
Distribution and panelboard SPD’s shall be labeled Type 1 with 7 modes of
protection: 3 modes (line-to-ground), 3 modes (line-to-neutral), and 1 mode (neutralto-ground) for a 3-phase, 4 wire plus ground voltage system. (Line-to-Neutral-toGround is not an acceptable substitute for Line-to-Ground).
Provide an SPD at the panelboard powering the security camera head-end
equipment.
The UL 1449 Clamping Voltage for the following configurations shall not exceed the
following:

The unit shall be UL 1283 listed as an electromagnetic interference filter.
Standardized insertion loss data shall be obtained using MIL-STD E220A 50W
insertion loss methodology. Minimum insertion loss shall be as follows:
FREQUENCY[MHz]
0.1
1.0
10.0
100.0
INSERTION LOSS[dB]

7.
SPDs shall use a separate path to building ground, the equipment safety ground is
not to be used as a transient ground path.
8. SPDs shall be constructed using metal oxide varistors (MOV) based modules. Each
SPD shall have a response time of less than one nanosecond with 6 inches or less of
connected lead length for any individual protection mode.
9. Each MOV contained within a current diversion module shall be individually fused
(component level safety fusing). For the assurance of safety purposes, this feature
shall be a standard design feature and not an optional feature of the product. The
individual component level fusing shall allow a reduction of protection rather than an
automatic complete loss of protection.
10. The maximum continuous operating voltage (MCOV) of all components shall not be
less than 125 percent for a 120/208 volt system with MCOV of 150 volts and 115
percent for 277/480 volt, systems with MCOR of 320 volts.
11. The minimum surge current capacity (single pulse rated) per phase shall be:
