.7 STRIKE ECS Installation
This section describes installation of the STRIKE Electronic Control System (ECS). Prior to system
installation, a complete system design based on a PCU analysis must be established, and a
proposed system layout or schematic, including a bill of materials, shall be created per Chapter 3.
Always contact the local AHJ for fire codes and health inspectors for special requirements
associated with any proposed installation. All installations are to be in accordance with NFPA 17,
NFPA 72 (National Fire Alarm Code), NFPA 70 (National Electric Code), and all other state and local
codes.
4.7.1 Steps to System Installation
The appropriate quantity and selection of heat detection devices, actuators, manual pull, pressure
switches, relay modules and any other devices must be made after a system design has been
completed. Appropriate lengths and selection of Amerex supplied wiring cables must be made to
accommodate the particular devices installed and their locations. Materials such as EMT conduit
and fittings, fasteners, clamps, and mounting hardware are not provided by Amerex and shall be
installer supplied. Any field wiring for relay modules or auxiliary FACPs shall also be installer
supplied.
•
The STRIKE Control Unit must be properly located and installed (See Section 4.7.2).
•
The appropriate detection devices must be located and installed (See Section 4.7.3).
•
All Linear Actuators for suppression system actuation must be installed (See Section 4.5).
•
All Manual Pull Stations must be located and installed (See Section 4.7.8).
•
All Pressure Switches used in a suppression system must be located.
•
Any optional devices, including Relay Modules and the supported devices such as external
alarms, fans, motors, etc., must be located and installed (See Section 4.7.9).
•
Appropriate wiring paths must be established and wiring installed, including any required
protective conduit from each device to the STRIKE Control Unit (See Section 4.8).
•
Once all needed cables and wiring are installed and securely routed back to and into the
STRIKE Control Unit enclosure, each cable must be terminated to the provided terminal boards
(See Section 4.9).
•
Once all wiring connections are made, STRIKE Control Unit programming may be performed
as required (See Section 4.10).
•
Component testing and initial commissioning must be performed prior to placing the system
into service (See Section 4.11).
4.7.2 STRIKE
Control Unit Installation
The STRIKE Control Unit (P/N 23826) must be surface mounted in a convenient location, permitting
inspection and periodic maintenance and minimizing wiring and cable lengths. Proper routing of all
wiring and cables to each system component is required and should be considered when choosing
an appropriate location. Any obstacles, moving parts, hazard areas, or bulkheads that may inhibit
complete connection of all system components, or cause damage to components, must be avoided.
The STRIKE Control Unit must be mounted in a location where the audio and visual indicators on
the face of the unit may be seen and heard easily. The STRIKE Control Unit must be mounted in a
dry location safe from any potential moisture or damage and must be
mounted to a surface capable
of supporting the weight of the unit and any additional mounting or wiring components.
