Model MC-1 (MC-2) Manual Control Station For Deluge And Preaction Systems Manual Release Service Page 1 of 2 AUGUST 2018 TFP1382 Worldwide Contacts www.tyco-fire.com IMPORTANT Refer to Technical Data Sheet TFP2300 for warnings pertaining to regulatory and health information. General Description The TYCO Model MC-1 (MC-2) Manual Control Station provides a tamper resistant means for emergency release (that is, operation) of TYCO Automatic Water Control Valves. Interconnec- tion with the valves may be direct via hydraulic (wet) pilot line or indirect via pneumatic (dry) pilot line to a Model DP-1 Dry Pilot Actuator. The MC-2 Manual Control Station is a modified MC-1 designed for use as a trim component for the Model DV-5a Automatic Water Control Valve. NOTICE The Model MC-1 Manual Control Station described herein must be installed and maintained in compliance with this document, as well as with the applicable standards of the NATIONAL FIRE PROTECTION ASSOCIATION, in addition to the standards of any other authorities having jurisdiction. Failure to do so may impair the performance of these devices. The owner is responsible for maintain- ing their fire protection system and devices in proper operating condition. The installing contractor or sprinkler manufacturer should be contacted with any questions. Technical Data Approvals UL and UL Listed FM Approved Working Water Pressure 20 to 300 psi (1,4 to 20,7 bar) Minimum Ambient Temperature Dry Pilot Lines: −50°F (−46°C) Wet Pilot Lines: 40°F (4°C) Assembly The box and cover in Figure 1 are thermo- plastic. The elastomer water seal is TEFLON. Operation Operating instructions are imprinted on the Cover, and the Cover is hinged to the Box and is held up in its normally closed position by a polystyrene Break Rod. The Break Rod is inserted through corresponding holes in the top of the Cover and interior of the Box, and the Break Rod does not extend above the top of the Cover so as to prevent unno- ticed tampering (that is, the Cover can only be opened by breaking the Break Rod). After actuation of the MC-1, interfer- ence between a boss on the interior of the Cover and the Operating Lever prevents closing of the Cover, before the Operating Lever is raised. As an added precaution, the Cover has been weighted such that it will not remain closed unless a Break Rod has been placed in position. Opening of the Model MC-1 Manual Control Station relieves hydraulic or pneumatic pressure, as applicable, which permits the automatic water control valve to open and allow a flow of water into the system piping. Installation When the TYCO Model MC-1 (MC-2) Manual Control Station is provided as a trim component for TYCO Automatic Water Control Valves, MC-1 (MC-2) must be installed in accordance with the specific instructions provided with the TYCO Automatic Water Control Valve Technical Data Sheets. When the MC-1 is utilized for remote locations on either wet or dry pilot lines, the following instructions apply: Step 1. The piping to the MC-1 is to be securely mounted, and the MC-1 is to be located 4-1/2 ft to 6 ft above the floor/ground level. Step 2. The MC-1 is to be installed ver- tically (so that the Cover will fall open when the Break Rod is not in place), in plain view, and in a readily accessible location. Step 3. When used with a wet pilot line, piping from the outlet of the MC-1 is to be directed to a suitable drain such that there will be no accidental damage to property or danger to persons when the MC-1 is operated. When used on dry pilot lines, the outlet piping is to be directed towards the rear of the MC-1 and away from the operator. Design Criteria The TYCO Model MC-1 (MC-2) Manual Control Station located at the TYCO Automatic Water Control Valve is to be reset in accordance with the specific instructions provided with the TYCO Automatic Water Control Valve Techni- cal Data Sheets. When the MC-1 is utilized for remote locations on either wet or dry pilot lines, it is reset by raising the Operat- ing Lever, closing the Cover, and insert- ing a replacement Break Rod. NOTICE In order to ensure the proper maximum pull open force for the Cover, use only P/N 92-289-1-008 replacement Break Rods. It is recommended that a supply of spare Break Rods be maintained on hand.
