Digital Central Supervisory Alarm Panel A dependable, time-saving
system for single-location
monitoring of remote
ammonia leak detectors
Standard features
The Cool Air Incorporated Digital Central
Supervisory Alarm Panel is designed to monitor
up to 64 (depending on specific model)
Ammonia Leak Detectors, providing a central
alarm and monitoring location as well as
communicating the status of all connected Leak
Detectors via a standard field bus (when
optionally equipped).
The panel comes with these standard features:
Digital display showing the concentration level
of connected ammonia detectors (LBW-420
only)
Audible and visible warnings of excess leak
levels at any connected Ammonia Leak
Detector
Normally-open, normally-closed contacts for
communicating a common alarm to industry
alarm systems
NEMA 4, UL-listed enclosure with high quality,
UL listed components
Additional features
Affordable
One year warranty
Virtually maintenance free
Optional fieldbus to communicate status
and ammonia concentration levels to
connected building monitoring equipment.

for Ammonia Leak Detectors
Sequence of Operation
The Digital Central Supervisory Alarm Panel is
designed to monitor the required number of field
sensors from remote ammonia leak detectors. If a
remote detector detects a concentration of ammonia
exceeding the pre-set level (adjustable from 25 ppm to
800 ppm concentration of NH
3
), it will close a dry
contact which sends an alarm signal to the Digital
Central Supervisory Alarm Panel. The remote units can
be wired to send an audible alarm signal to the Central
Panel at both the early warning and emergency
alarm stages of ammonia concentration.
Available Fieldbus Models
The Digital Central Supervisory Alarm Panel supports
the following fieldbuses:
Modbus RTU
Ethernet /IP
Interbus
Modbus Plus
Modbus TCP
Interbus F.O.
Profibus DP
