Operating principle

General operation

Under normal, standby conditions, the pressure above the clack is greater or equal to the pressure below the clack; this holds the alarm valve in the closed valve position. By turning the Bellcheck pump on at the key-switch the pump operates and starts to pump water from above the alarm valve through an orifice plate to the chamber below the alarm valve clack.

As the pressure acting on the under-side of the clack is now greater than the pressure acting above it, the clack inside the alarm valve is pushed open. This allows water to pass through the annular groove to the mechanically driven alarm gong. The flow of water through the gongs chamber causes the gong to emit a continuous ring for as long as the clack is open.

A pressure-switch or flow-switch detects the increase in pressure (or flow) and submits an electronic signal to a remote alarm panel or suitable equivalent. This provides an alarm signal to indicate that the sprinkler system is in operation. The test is completed by turning the key-switch back to the standby position.

Overview

The Bellcheck® system provides a simple, water saving method for the water motor alarm testing to be carried out as part of the mandatory routine. Rules stipulate that as part of this routine, the gong is exercised on a regular basis. Turning the key-switch and allowing the gong to ring for a predetermined length of time fulfils the testing requirements. In the field, this means that suitable personnel can easily perform a fully code compliant test at the appointed time on each occasion using Bellcheck®.

On-site Requirements

Space requirements

Before installation it is important to determine that there is enough free space for the Bellcheck line to be installed. Installation requires two mechanical tees & two barrel nipples (not provided) positioned above and below the wet alarm valve arrangement (positioned 880±2 mm apart). In situations where space is restricted, replace the two barrel nipples with two short lengths of 1” BSP threaded galvanised pipework to allow for the Bellcheck to fit around the valve-station. In some scenarios the length of Bellcheck may need to be extended by replacing the 1” vertical pipe with a longer piece of pipe to suit site conditions.

Water-supply non-return valve

Please note that Bellcheck® works by pressurising the chamber beneath the alarm-valve clack. As the pressure increases water should force the ‘water-supply’ non-return valve shut and cause the chamber to increase in pressure until the alarm-valve clack lifts. It is important to establish that this non-return valve on the water supply is functioning correctly prior to the installation.

Alarm-valve

The wet-alarm valve used with Bellcheck® must meet the requirements set out in BS EN12259-2:1999 Part 2: Wet alarm valve assemblies standards.

Installation

Bellcheck should be installed by a competent fire sprinkler installer and wired up by a qualified electrician.

Ensure that the system is drained down and isolated prior to any works.

1. Assemble (hand-tight only) the Bellcheck® arrangement, including mechanical tees and marry it up to the valve station.

2. Remove the Bellcheck® line leaving just the mechanical tees and union-halves clamped to the existing pipework in the correct positions (see figure 3).

3. Mark the mechanical tee positions before removing them and drilling the two 1” connections into the pipe wall.

4. Re-connect the two mechanical tees back onto the pipe.

5. Marry up the Bellcheck® line with the union-halves (as per figure 4).

6. Ensure that the Bellcheck® line is aligned correctly and fully tighten the union connections using a spud wrench.

7. Use the temporary commissioning lead to connect the Bellcheck® spur box to a suitable 220v ~ 50Hz mains power supply.

Electrical Information

Bellcheck can be setup and tested by a competent fire sprinkler installer using the temporary commissioning lead. However, all permanent wiring must be carried out by a qualified electrician.

1. Remove the temporary commissioning lead and isolate the unit.

2. Connect a permanent 220 v ~ 50Hz; 2 amp power supply to the Bellcheck® spur box.

3. Wire the pressure-switch (or flow-switch) to the key-switch and fire detection panel.

Commissioning

1. Turn the key to standby at the key-switch (9).

2. Open the Bellcheck® pump inlet valve (6) and the pump outlet valve (7).

3. Check that all valves are now in the correct position according to the valve schedule.

4. Open the alarm manual test valve (3) until the alarm gong (5) sounds.

5. Close the alarm manual test valve (3) on the manual test line. 6. Turn the key-switch to test. Now check that both the pump and water-flow

green lights are on.

7. Allow the alarm gong (5) to ring for 30 seconds. Now turn the key-switch to standby and remove the key.

8. Check that all valves are left in the correct position corresponding to the valve schedule.

Weekly Test

Weekly Test (Bellcheck®)REF Fig. 6

1. Advise all applicable parties and alarm receiving stations of the planned routine test.

2. Visually check that the main inlet valve (1) is secured open.3. Check and record the pressures at the ‘B’ and ‘C’ pressure gauges.4. Insert the key into the key-switch (9); turn the key to the test position.5. When the water motor alarm gong (5) has sounded for 30 seconds, turn the key

to the standby position (9). (Note: this will cause the clack to re-seat, the gong to stop ringing and the water in the gong line to stop flowing to drain).

6. Remove the key.7. Record the pressures at the ‘B’ and ‘C’ pressure gauges.8. Contact any alarm stations to check that the system operated signal has operated

and reset. Or reset any locally connected alarm panel.9. Record the test results.
