Eclipse BoostPak Leak Detection Option, V3, Installation Guide 630-LD 7/30/2010
Electrical Installation
Refer to the system drawing 10025035 shipped with the
control panel.
• Incoming power supply connects to 1022 (hot),
1023 (neutral) and GND (ground).
• Power to operate the gas valve comes from the
control panel terminals 1083 (hot), 1023 (neutral)
and GND (ground).
• Position switches from the valve wire to control
panel terminals 1021 (hot), 1041 (closed position),
and 1051 (open position).
• The remote sensor requires low voltage 2-pair, 4-
conductor shielded cable, Belden #1325A. Keep the
wiring length less than 100 feet.
Terminals are provided for optional customer interface.
The total of all loads must not exceed 7.5 amps. A jumper
wire between panel terminals 1021 and 1171 provides
powered outputs. If dry (voltage free) contacts are
required, remove this jumper and use 1171 as the
common. The functions are Entry OK (1172), Leak
Detected (1181), Leak Cleared (1191) and Pre- Warning
(1201).
The Leak Detect option can operate independently of the
BoostPak control system. A leakage condition will shut
down the BoostPak without a direct wiring connection if
the low gas inlet switch is downstream of the gas valve.
If a direct connection is needed, it can be wired in series
with the run interlocks or in series with the low inlet gas
switch. When connected to the run interlocks, a leak
detect will provide a normal shutdown of the BoostPak
(refer to the appropriate installation guide). When
connected to the low inlet gas, a leak detect will result in
an alarm condition shutdown.
Checklist After Installation
To use a direct connection, remove the leak detect
annunciation panel (LDAP) jumper from 1021 to 1171 and
connect the Entry OK contact into the BoostPak panel
(BPCP), in accordance with one of the two following
methods.
1. For normal shutdown on leak detection, remove the
jumper* from BPCP 2161 to 2162. Connect LDAP
1171 to BPCP 2161 and LDAP 1172 to BPCP 2162.
* Note, if the BoostPak system uses a High Inlet Gas
switch, the jumper is not present and the connection
will need to be in series with the wire from that switch.
2. For alarm condition shutdown, remove the Low Inlet
Gas switch wire from BPCP 2121 and connect it to
LDAP 1171. Then connect LDAP 1172 to BPCP 2121.
Ensure the system was properly installed and verify:
• The control panel terminals are tight; shipping may
have caused loosening.
• The gas flow through the shut off valve has the
proper direction.
• The detector module and remote sensor are
installed in appropriate locations and at appropriate
heights.
