For example, if the source equipment’s normally closed contact is wired to the “+” of the ﬁrst master panel, ensure it is also connected to the “+” terminal of the second master panel.

2.3.7 B4X Relay Output Board

A Master or Combination alarm can contain multiple relay output boards; up to a maximum of 4 boards with 16 relay outputs each. The B4X boards (B40, B41, B42, B43) utilize normally closed dry contact relay outputs.

Figure 25: B4X Board Wire Routing

The outputs on the B4X boards are labeled Y01 through Y16.

Identify each pair of ﬁeld installed relay output signal wires inside the alarm rough-in box. Route each pair of relay output wires as shown in Figure 25 to the appropriate terminals on the relay board. Connect each pair of signal wires to the terminal blocks, noting the correct polarity (+,-). Refer to NFPA Mas-

ter/Combination Wiring Diagram (Section

3.1/3.3).

2.3.8 B50 4-20mA Combination Board

A Combination alarm can contain a B50 board that contains four 4-20mA inputs that can be used with a 2 or 3 wire transmitter. The board also contains seven signal inputs, which monitor normally closed signal inputs, and six normally closed dry contact relay outputs. Each alarm panel can have a maximum of one B50 board.

Identify each set of ﬁeld installed 4-20mA input signal wires (2 or 3 wires per set) inside the alarm rough-in box. Route each set of input wires to the appropriate terminals on the B50 board. Connect each set of signal wires to the terminal blocks, noting the correct polarity (Figure 26).

2.3.9 General Fault Relay

The B60 Gas Input board is supplied with an alarm panel general fault output relay.

This relay has a set of dry contacts that is wired normally closed.

The relay will activate when ANY alarm on the ENTIRE alarm panel is activated. Relay will remain activated as long as alarm condition is active, even if audible alarm is silenced by MUTE button.

When alarm condition is corrected, relay will deactivate. Relay contact ratings are 35A @ 30VDC / 3A @ 250VAC. Refer to NFPA Area

Wiring Diagram (Section 3.2).

• Gas pressure value

• Gas pressure status (Low, Normal, or High)

Figure 36: Gas Badge

Figure 35: MEGA3 Alarm Main Screen

4.1.1 Main Screen

The ﬁrst screen that users see on a conﬁgured unit is the MAIN screen. The MAIN screen is the main view for the alarm and shows the pressure status of all of the gases (area) or source signals (master) the alarm is monitoring.

NOTE:

The main screen will appear dierent depending on whether the alarm panel is conﬁgured as an area, master or combination.

An area alarm main screen will show gas badges, a master alarm main screen will show source signals, and a combination alarm main screen will show both gas badges and source signals.

4.1.3 Source Signals

Every source signal monitored by the alarm will display the following information once conﬁgured:

• Equipment being monitored

• Location of the source equipment

• Signal being monitored

• Source signal status Red (open - in alarm) or Green (closed - normal).

The display can show the status of up to 40 signals. The hardware installed limits how many of the 40 signals can be used.

5.3.2 Determine Proper Placement of New Components

1. Determine the proper placement of the MEGA3™ Retroﬁt Alarm components inside of the rough-in box. Refer to Appendix A and illustrations for recommended placement.

NOTE: I/O Modules and Power Supply will need to be daisy chain connected via the grey cables supplied with each I/O module (See Figure 122) The last module in the chain needs to have the #1 DIP switch set to “ON” (See Figure 123).

2. If alarm is an Area or Combination with local sensors, consider the position and placement of the pressure transducers before drilling or mounting any components. Use the sensor adapter kits provided to relocate the sensors if required.

5.3.3 Install Gas-Speciﬁc Sensors (Area or Combination alarms only)

Local Sensors

1. Install the MEGA3™ gas speciﬁc transducers following your records from the disassembly.

NOTE: If a DISS demand check valve is not in place then one will need to be installed to comply with NFPA 99.

CAUTION: Ensure that the pressure on the pipeline in the alarm area has been released before removing any components from the pipeline connection.

2. Remove any existing ﬁttings or adapters from the gas tube in the rough-in box.

4. Tighten the adapter until you feel resistance; then turn the ﬁtting 2 full turns.

5. Install the gas speciﬁc transducer.

6. Tighten the DISS nut until you feel resistance.

7. Repeat steps 2-6 until all of the gas speciﬁc transducers are installed.

8. Verify that the gas speciﬁc transducers are in the appropriate places by referring to your records from the disassembly.

9. Return pressure to each gas sensor, one gas at a time and check for leaks. Make any adjustments or corrections as needed.

Remote Sensors

1. Sensors are packaged loose so they can easily be installed remotely.

2. Remote sensors are installed directly to the pipeline outside of the rough-in box. Pipeline connections are to be made to the top of the pipe.

NOTE: If a DISS demand check valve is not in place then one will need to be installed to comply with NFPA 99.

CAUTION: Ensure that the pressure on the pipeline in the alarm area has been released before removing any components from the pipeline connection.

3. Remove any existing ﬁttings or adapters from the gas tube.

5. Tighten the adapter until you feel resistance; then turn the ﬁtting 2 full turns.

5.3.6 Install Trim Components

The standard retroﬁt alarm kit comes with a 20” x 16” trim plate assembly which will work for most of the typical installations (Figure 135). In some cases the trim plate is not needed and the existing rough-in box / wall opening can be covered by using the trim ring alone; in that case, remove the 20” x 16” trim plate prior to installing the trim ring to the wall/rough-in box.

For retroﬁtting of larger 8-gas rough-in panels (up to 24” wide), an optional trim plate kit is required (4107220615) to cover the larger wall opening (Figure 136). If this is required, remove the 20” x 16” trim plate from the trim ring and install the 27” x 16” trim plate prior to installing the trim assembly to the wall/ rough-in box. *Note the orientation of the square notches on the trim ring and plate.

1. Position the trim plate over the roughin box and determine the best mounting method for your case. Use a level to check that the trim plate is plumb.

2. Mark the mounting locations on the drywall using the trim plate as your guide.

3. Install the drywall anchors provided as needed.

4. Reposition the trim plate and install the screws provided into the anchors and/or directly into the rough-in box.
