2.0 Installation Procedures
2.1 Alarm Panel Rough-In Box
The rough-in box can be installed between
16” on center standard studs. Mounting
ears on either side of the rough-in box are
provided for attachment to studs, with depth
adjustment to accommodate dierent thick-
nesses of wall board.
Knock out plugs are provided in the top and
bottom of the box for routing of supply pow-
er, Ethernet CAT5 cable, gas sensor tubes, or
other necessary wiring.
DO NOT drill rough-in box.
1. Prepare rough wall opening large enough
to accommodate alarm rough-in box.
Alarm rough-in box must have rigid verti-
cal members for support on both left and
right sides. Power to alarm panel shall en-
ter through bottom left or top left conduit
hole in rough-in box.
2. Remove cardboard dust cover and DISS
tube assemblies (if included) and insert
alarm rough-in box into wall opening.
[Secure with fasteners suitable for vertical
supports (Figure 16)].
3. Mounting brackets on each side of rough-
in box are adjustable and factory preset
for 5/8” thick drywall. After drywall
installation, front edge of rough-in box
should be flush with finished surface
of wall. If needed, make any necessary
bracket adjustments at this time (Figure
16).
4. Reinstall cardboard dust cover to prevent
dust and debris from entering the rough-
in box.

2.2 Gas Sensor Installation
2.2.1 Locally Installed Sensors
1. Locate copper adapter tube(s) packaged
inside the alarm rough-in box.
2. Install tube(s) into the top of the rough-
in box through the holes provided.
Notice the Gas ID labels and position
appropriately for connection to the
hospital piping. Apply Gas ID label
provided with tube adapter to the
inside of the rough-in box to identify
the ports after walls are closed in.
3. Braze copper adapter tube(s) to
appropriate pressure/vacuum piping
system drops (Figure 17). Braze
connections per procedures required
by NFPA 99 or CAN/CSA-Z7396.1-12.
Use appropriate measures to prevent
overheating.
4. Install the Gas Specific DISS check valve
into the appropriate tube adapter.
5. Perform standing pressure test and cross
connection tests as required by NFPA and
CSA.
2.2.2 Remotely Installed Sensors in
Pipeline
1. Sensors can be installed onto the hospital
pipeline.
2. Braze copper adapter tube(s) to
appropriate pressure/vacuum piping
system connections (Figure 18).
3. Braze connections per procedures
required by NFPA 99 or CAN/
CSA-Z7396.1-12
4. Use appropriate measures to prevent
overheating.
5. Install the Gas Specific DISS check valve
into the appropriate tube adapter.
6. Perform standing pressure test and cross
connection tests as required by NFPA and
CSA.
2.2.3 Remotely Installed Sensors in
Zone Valve Box
1. Remote sensors can be installed in a
compatible BeaconMedæs Zone Valve
Box. (NOTE: copper adapter tube not
needed for Zone Valve box installation
(Figure 19).
2. For Zone Valve Box mounting, an
additional Installation Kit is required, part
number 4107 4016 25 for each sensor.

2.3 Wiring
2.3.1 General Requirements
1. All alarms are to be powered from life
safety branch of emergency power system
as required by applicable standards.
2. Protect all wiring from physical damage
by raceways or conduit as required by ap-
plicable standards.
3. Wire alarm panels directly to switches or
sensors as required by applicable stan-
dards.
4. Wiring runs should be made with color
coded wire. Record color, signal, and
source of signal for each wiring lead to
aid in connection of alarm finish compo-
nents.
5. Avoid installing alarm panels near radio
transmitters, electrical motors, or switch
gear.
Figure 19: Zone Valve Box Location
2.3.2 Wire Type and Size
All low voltage wiring must meet the follow-
ing criteria:
• Copper wire no smaller than 22 AWG,
conductor insulation at least 0.010in
(0.25mm), jacket insulation at least
0.030in (0.76mm), rated for 300V and
60°C (140°F) minimum.
• Circuit length not to exceed 5000 feet.
• Cable must be twisted-pair shielded type.
Multi-pair cables within one common
shield are acceptable.
2.3.3 Determining Number of
Conductors
The following rules along with references
to this manual’s schematics clarify wiring
requirements.
• Digital Gas Sensor Modules
Two conductor cables (must be twisted pair
type with shield) are required for each Gas
Sensor module to the Gas Input board.
Refer to NFPA Area Wiring Diagram (Section
3.2).
• Switched signal inputs
Two conductor cables (must be twisted pair
type with shield) are required for each signal
between the signal input terminals and the
source signal switch.
These signals can originate at source equip-
ment or from pressure switches mounted on
main pressure / vacuum pipelines.
When two master alarms are required, the
same switch / relay contacts can be wired to
both alarm panels. (See CAUTION below).
Both pairs of wires should originate from
switch/relay contacts.

2-4
MEGA3 NFPA Medical Gas Notification System
4107 9016 59.03
Refer to NFPA Master/Combination Wiring
Diagram (Section 3.1/3.3) for B1X, B50, B65
signal boards.
• Relay outputs
Two conductors are required for each signal
between relay output terminals and remote
device (such as a building automation sys-
tem). Refer to the wiring requirements of the
connecting device when selecting the ap-
propriate type of conductors to use (i.e.. wire
gauge, twisted or not, shielded or not.)
Refer to NFPA Master/Combination Wiring
Diagram (Section 3.1/3.3) for B4X, B50, B65
signal boards.
2.3.4 Power Supply
A power supply assembly is provided with
the alarm panel. The installer must use
18AWG copper supply wiring minimum
with an insulation of not less than 1/32 inch
(0.8mm) thick. Power supply shall be con-
nected to a building installed circuit breaker.
Circuit breaker shall be a maximum of 15
amps and marked as disconnecting means for
the alarm panel. It is recommended that the
circuit breaker be in close proximity to the
alarm panel and properly selected according
to local and national regulations.
Holes are provided in the top and bottom of
the rough-in box for main power (Figure 20).
If power is entering from the top, it must be
routed under the cable raceway.
NO OTHER HOLES SHOULD BE PUNCHED
OR USED.
Several additional holes or knockouts are pro-
vided on the top panel and bottom for en-
trance of low voltage field wiring (Figure 20).
Alarm panels require 100 to 250 VAC
0/60 Hz 250mA power. NFPA Area Wiring
Diagram (Section 3.2).

Do not connect MEGA3 master/combina-
tion alarm to switch/relay contacts connect-
