- Two locked access doors to reduce front area required for opening, easily removable without tools to allow easy installation & servicing.
- Individual access doors for the hydraulic electrical sections and the emergency release with a neoprene gasket to avoid vibrations.
- Viking Deluge Valve model E, complete with releasing trim rated at 250 psi and all the necessary accessories. Trim shall include a mechanical latching device to prevent system from resetting in case of loss of power to the release solenoids. 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, priming water and air pressures 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.

- Field wiring terminal strips integrated with the cabinet for connection of field wiring for auxiliary contacts and power supply for the optional air compressor (see art. 2.3.4 for details).
.2 The cabinet assembly must be pre-assembled, pre-wired and factory tested under ISO-9001 conditions, as a Viking TotalPac2 System, 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:
o Yes o No Provide a Listed and Approved isolation butterfly valve installed on the system riser inside the cabinet for full flow test purposes. The valve shall be supervised by the same supervisory circuit as the system main water supply valve tamper and wired at the factory. An integrated sight glass shall be part of this arrangement for visually confirming water flow through the main drain upon system actuation. A detailed instructions placard must be provided inside the cabinet door for easy reference.
o Yes o No Provide a tee connection inside the cabinet with an opening on the right side of the cabinet enclosure for connection to the Fire Department Connection.
o Yes o No Seismic Option The TotalPac2 cabinet shall include a seismically-rated cabinet construction that meets the highest max earthquake found, location Portageville, 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 Integrated Control Panel
.1 The release control panel must be fully integrated to the TotalPac2 cabinet and installed in his own enclosure, mounted at the factory on top of the trim enclosure. Standard wall enclosure normally provided with control panels shall not be used and this arrangement shall be fully Listed & Approved as part of the integrated unit. Panels provided with their regular wall mounted enclosure fitted in the front door of the cabinet will not be considered as fully integrated and shall not be acceptable.
.2 The control panel shall be FM Approved and cULus listed to the new UL 864-9 standard. Panel shall include four programmable Class B, Style B initiating zones, two class B supervisory zones, and four programmable output circuits. Onboard, menu-driven programming with twelve pre-installed programs for ease of set-up must also be provided. The panel must be compatible with many different initiating devices including linear heat detection, smoke and heat detectors, water flow indicators, low air pressure switches, and manual pull stations.
.3 The control panel should include both an LCD Annunciator describing all system conditions (16 characters on 2 lines) and a set of red & yellow LED lamps identifying each separate alarm and trouble conditions. Easy to operate control buttons shall also be included for the operation of the panel various functions.
.4 The control panel should be pre-wired at the factory to a set of industrial grade wiring terminals used for power feed, separate from the terminals used to power the optional air compressor. External wiring to field devices (outside the cabinet) should be wired directly to the control panel module by the installing contractor on-site.
.5 A set of emergency batteries should be provided with the control panel. Batteries should be calculated to provide emergency power for a specific duration after which they shall be able to provide 5 minutes of alarm and activation of the solenoid valve(s).
Choose required stand-by duration:
o 5 minutes of alarm after 24 hours stand-by (UL)
o 10 minutes of alarm after 90 hours stand-by (FM)
2.4 Control Panel Options
Choose applicable options:
o Class A, Style D initiating device circuits: When Class A, Style D wiring is mandated by the Authority Having Jurisdiction, the contractor shall provide CA2Z modules and install them on-site.
o Class A, Style Z indicating appliance circuit: When Class A, Style Z wiring is mandated by the Authority Having Jurisdiction, the contractor shall provide CAM modules and install them on-site.
o Remote Annunciator: When a remote annunciator is mandated by the Authority Having Jurisdiction or local codes, the contractor shall provide a model RA-4410RC remote annunciator module and install it on-site following the instructions provided by the manufacturer. Remote annunciator shall be mounted on a standard four gang wallbox provided by the contractor. Remote Annunciator should also include the following features:
a)33 red & yellow LED lamps to annunciate various system status;
b)Trouble and supervisory buzzer with combined silence/lamp test switch;
c)RS-485 interface with the release control panel allowing up to 4 remote annunciators to be connected to the control panel.
2.5 Detection & Signalling
Devices .1 Supply and install a complete electrical detection system including:
- system tubing, wiring, smoke detectors, signaling devices and connections to auxiliary functions.
.2 Heat and/or smoke detectors can be wired on either zones 1 or 2. Where more than the allowable quantity of detectors are required on a same detection zone, use the recommended 4-wire type detector base for that detector. Spacing and type of detectors shall meet the requirements of the applicable standards and the manufacturer's recommendations for the application protected.
.3 The detection and alarm indicating devices (24 Vdc bell, horn or strobe) must be compatible with the release control panel.
.4 A bell or a horn should be installed near the TotalPac2 cabinet.
.5 Supervisory tamper and pressure switches mounted inside the cabinet by the factory should be wired to two separate zones and provide separate indications for tamper and air supervisory.
Note: Refer to the applicable compatible device list provided in the panel Installation, Operation & Instruction Manual to determine which compatible initiating and signaling devices model number to use.
2.6 Signalling Options
Choose applicable options:
o The VFR-400 panel provides 4 sets of dry contacts. When additional dry contacts are required, use Viking p/n MR-101 (SPDT), MR-201 (DPDT) and / or MR-801 (SPDT with LED). These field devices shall be installed OUTSIDE the TotalPac2 enclosure and are provided by the installing contractor.
2.7 System Operation
System sequence of operation shall be pre-set at the factory (Factory Program #10) and perform the following:
.1 The activation of the detection condition AND the opening of an automatic sprinkler are BOTH necessary to cause the water discharge.
.2 Activation of a detection zone will energize the solenoid valves, open the deluge valve and cause the system to fill the piping network with water. This will sound an alarm, and activate alarm and water flow contacts for auxiliary functions. No water will flow until a sprinkler head fuses.
.3 The opening of an automatic sprinkler OR damage to system piping without electrical detection will initiate the sounding of a warning device and the activation of an alarm contact but will not cause the system to fill.
.4 Operation of the emergency manual release will depressurize the priming chamber of the deluge valve, causing the system to fill the piping network with water, and activate alarm and water flow contacts for auxiliary functions. No water will flow until a sprinkler head fuses.
.5 If the AC Power fails and the battery backup power expires before a fire is detected, the preaction system should “fail-safe” and function as a dry pipe system. The opening of an automatic sprinkler OR damage to system piping will cause the system to fill and flow water until it is manually shut-off.
