Design Criteria
The TYCO Model WMA-1 Water Motor Alarm must be used in accordance with this section.
Item 1. The Y-strainer is to be located at the inlet to the Water Motor Alarm.
Item 2. The Water Motor Alarm must only be mounted to a rigid wall surface, which will not permit the Striker / Gong Mount to loosen and fall out of alignment.
Item 3. In order to obtain the highest possible sound level, the Water Motor Alarm should be located as close as possible to the waterflow detecting valve.
Item 4. The alarm line piping from the alarm outlet of the waterflow detection valve trim to the Water Motor Alarm must be DN20 inch size throughout and it must be galvanized steel, brass, or other suitable corrosion resistant material.
Item 5. The alarm line piping must be positioned such that it can be drained back to the waterflow detection valve trim.
Item 6. The Clean-out Sump Plug is to be located vertically below the Inlet to the Water Motor.
Item 7. Piping from the Water Motor Drain must be a minimum of DN25 inch in size throughout and directed to an open drain, in order to ensure proper drainage for obtaining the maximum sound pressure level.
The Water Motor Alarm Drain may be connected to the main drain of a waterflow detection valve if a non- spring loaded swing-type check valve is installed in a horizontal portion of the water motor alarm drain piping (before its connection to the main drain).
Item 8. In order to minimize any wall staining that can be created by drain water, it is recommended that the drain piping from the Water Motor be galvanized steel, brass, or other suitable corrosion-resistant material.
Item 9. Drain water must be directed such that there will be no accidental damage to property or danger to per- sons when the alarm is operating or thereafter.
Item 10. The alarm line drain (at the waterflow detection valve) must be maintained at a minimum temperature of 4°C. |

| Step 1. Mark the through-wall locations for the centerlines of the Sleeve and Drain Outlet. The Drain Outlet must be located at least 250 mm below the Sleeve per.
Step 2. Make 38 mm diameter holes straight through the wall at both locations.
Step 3. Cut the non-threaded end of the Sleeve to a length equal to that of the wall thickness plus 0 to 3 mm. Thread the cut end to ISO 7-R 3/4 per ISO 7-1. |

| Step 10. Hold the Gong Mount in position against the wall, engage the Coupling with the Drive Shaft and then carefully thread the Striker Shaft Bearing onto the Sleeve. Securely tighten the Striker Shaft Bearing using a pair of channel locks on the 38 mm hex end.
Step 11. Spin the Striker by hand and verify that it spins freely (without any sign of binding). If not, make the necessary adjustments.
Step 12. Install the Gong and securely tighten the Cap Nut. The identification sign lettering must be orientated horizontally.
Step 13. Test the Water Motor Alarm by opening the alarm test valve in the trim of the waterflow detection valve. The alarm must be clear and steady. If not, make the necessary adjustments.
Note: Testing of the Water Motor Alarm may result in operation of other associated alarms. Consequently, notification must be given to the owner and the fire department, central control station, or other signal station to which the alarms are connected. |

| Care and Maintenance
The TYCO Model WMA-1 Water Motor Alarm must be serviced and maintained in accordance with this section.
Before closing a fire protection system main control valve for maintenance work on the fire protection system that it controls, permission to shut down the affected fire protection systems must first be obtained from the proper authorities and all personnel who may be affected by this decision must be notified.
The following procedures and inspections should be performed as indicated, in addition to any specific requirements of the authority having jurisdiction, and any impairment must be immediately corrected.
The owner is responsible for the inspection, testing, and maintenance of their fire protection system and de-vices in compliance with this document, as well as in addition to the standards of any authority having jurisdiction. Contact the installing contractor or product manufacturer with any questions.
It is recommended that automatic sprinkler systems be inspected, tested, and maintained by a qualified Inspection Service in accordance with local requirements and/or national codes.
Testing of the Water Motor Alarm may result in operation of other associated alarms. Consequently, notification must be given to the owner and the fire department.
If the alarm was silenced during operation, the alarm control valve must be reopened immediately after the fire protection system is restored to service. |

| The Model WMA-1 Water Motor Alarm must be maintained and serviced in accordance with the following instructions:
Step 1. The Model WMA-1 Water Motor Alarm does not require any regularly scheduled maintenance. Rotating parts do not require lubrication. It is recommended, however, that fire alarms be periodically operated, i.e., inspected, to verify that they generate a clear and steady sound. Any impairment must be immediately corrected.
Step 2. The inspection should be made periodically in accordance with the requirements of the authority having jurisdiction, or more frequently as may be necessary in the case of locations subject to vandalism. The Y-Strainer and the Reducing Tee at the WMA-1 inlet are to be cleaned out after each operation of the
Water Motor Alarm and after the alarm line piping has been drained.
