Systems provided with solenoid only, without this mechanical latching device shall not be accepted. Every valve shall be clearly identified as to its operation with arrows indicating all positions to facilitate system operation.
-Pressure gauges to indicate water supply and priming water pressure of the system. Each pressure gauge must be provided with its own shut-off valve and shall be clearly identified on the outside of the cabinet front door.
-Schedule 40 galvanized steel release trim with solenoid valve and each supervisory and alarm device required. Black pipe will not be accepted.
-Schedule 40 steel pipe header painted fire red, with grooved ends to be connected to supply water from either side.
-Schedule 40 steel pipe drain manifold of 2" diameter painted fire red, with grooved ends for drain connections from either side.
-Properly identified contractor test ports factory mounted into the trim piping to facilitate system testing and commissioning.
-Field wiring terminal strips integrated with the cabinet for connection of field wiring for remote detection system and audible devices.
.2 The cabinet assembly must be pre-assembled, pre-wired and factory tested under ISO-9001 conditions, as a Viking TotalPac2 by FireFlex Systems Inc. It shall also be c-UL-us Listed and FM Approved as an assembled unit.
2.2 Cabinet Options
Choose applicable options:
Yes No.1Tee connection inside the cabinet with opening on the right side of cabinet enclosure for connection to the Fire Department Connection.
Yes No Seismic Option The TotalPac2 cabinet shall include a seismically-rated cabinet construction that meets the highest max earthquake found, locationPortageville, Missouri, Site Class "D" Occupancy CATEGORY IV, Importance factor I = 1.50, SDC "D". The cabinet assembly shall have been subjected to seismic testing (ie – shake table test) and be OSHPD pre-approved under OSP-0104-10
The anchors shall be calculated by a structural engineer or utilize anchoring detail as per installation details found in TotalPac2 Seismic Option datapage # FM-076D-0-7.
2.3 Detection & Signalling
Devices
WARNING: Use only Viking Firecycle® heat detectors. No other type of detector is compatible with Multicycle systems.
.1Supply and install a complete electrical detection system including:
-System tubing, wiring, Firecycle® heat detectors and signaling devices.
.2Firecycle® detectors shall be wired to allow automatic discharge control.
Choose applicable options:
Yes NoLight & Ordinary Hazard: Only model C Viking Firecycle®-OH detectors shall be used on this zone. The detectors shall be connected with FPL plenum type cable in series from and to the Multicycle preactioncabinet.
OR
Yes NoExtra Hazard: Only model B Viking Firecycle® detectors shall be used on this zone. The detectors shall be connected with fire resistant detector cable (Viking Firecycle® detector cable) in series from and to the Multicycle preactioncabinet.
.3The Firecycle® detectors and the audible devices (bell & horn 24 VDC) must be compatible with the release control panel.
.4A bell and horn should be installed near the TotalPac2 cabinet.
2.4 System Operation
Contractor should make sure the remote release control panel sequence of operation is programmed to perform the following:
.1The activation of a Firecycle® detector will initiate the sounding of a warning device and the activation of alarm contact for remote transmission.
.2Once a sprinkler head has fused, discharge is immediate and shall continue for as long as any Firecycle® detector remains in alarm. When ambient temperature is lowered below all the Firecycle® detectors trip point, detectors reset themselves automatically. At this moment, a soaking timer is activated, allowing water to flow for an additional period of time. At the end of the Soak Timer delay, the flow of water is automatically stopped.
Soak-timer value shall be adjusted to: ___ minutes, ___ seconds.
At the end of the Soak timer delay, waterflow is automatically stopped. If any Firecycle® detector is reactivated by heat, water discharge is immediately reactivated, and the same soaking timer delay will be applied once all detectors have cooled down and reset. Stopping the flow of water should be maintained only when the detection zone is not activated and the timer cycle is ended.
.3Operation of the electric manual release pull station shall activate the same functions as a thermal detector except that the Multicycle function will be by-passed and system will discharge until Main Control Valve is manuallyshut-off.
2.5 Failsafe Mode
.1The Normally Closed Firecycle® Detectors should form asingle-line
closed loop. When the heat detectors are exposed to the heat of the fire, their contacts shall open. When the detectors cool off below their set point, the contacts shall close.
If exposed to excessive temperatures for extended periods, the detectors shall normally fail with an open contact. If the detectors wiring is broken due to physical damage, the system's control panel shall detect an open in the loop, as if a detector had operated.
.2The activation of a Firecycle® detector will initiate the sounding of a warning device and the activation of alarm contact for remote transmission and will cause the system to flow water.
.3Damage to system piping in the absence of an alarm, will flow water for approximatively 10 seconds (retard), initiate the control panel to energize the solenoid valves, closing the flow control valve and automatically stopping the flow of water, limiting water damage. Control panel will sound a warning device or activate an alarm contact.
2.6 Automatic Sprinklers
.1Supply and install all required automatic sprinklers. They will be glass bulb type, UL/ULC listed and FM approved.
.2Applicable specifications of automatic sprinklers shall be determined as per the manufacturer recommendations, based on the project conditions.
2.7 Piping
.1System piping and fittings shall be as recommended by NFPA 13.
2.8 System Drain
.1The single drain collector of the TotalPac2 system shall be connected to an open drain (open end pipe with an air gap around the drain pipe or equivalent). The drain piping shall not be restricted or reducedand shall be of the same diameter as the drain collector. It shall also be arranged to avoid back-pressurizing the drain trim. Multiple drain collectors and open drain cups inside the cabinet will not be accepted.
.2Manifolding of multiple units is permited provided the manufacturer's recommendations are carefully followed and complied with.
Part 3 - EXECUTION
3.1 Installation
