One LED on each module indicates normal
or abnormal gas line pressure status at a glance
Area alarms can monitor up to 6 medical gas
or vacuum services
Local or remote pressure sensing
Alarm module calculates high and low alarm
settings automatically
Primary power design accepts 115 or 230 VAC
(50/60 Hz)
UL listed and CSA approved
Description
Chemetron® area alarm panels shall be designed to meet
the requirements of NFPA and CSA standards. Alarms
shall be UL listed and CSA approved as an assembly and
shall include all necessary gauges, factory wiring, transformers and circuitry requiring only 115 volt or 230 volt
primary power. Internal voltage shall be stepped down to
5 volts DC for control circuit power. Voltage to external
pressure or vacuum transmitters will be 20 volts DC.
Area alarm panels shall be modular in design and have one
LED (Light Emitting Diode) to indicate each normal/
abnormal condition. Each gas monitored shall have an
LCD (Liquid Crystal Display) to continuously indicate
actual pressure.
The control module will have a test switch and an alarm
silence switch. The test switch shall test all modules one at
a time. There will also be an LED on the control module
to indicate status of the micro-controller (green is normal,
red is for a malfunction).
Each line pressure module shall have a normal/abnormal
LED, an LCD, and a window for the gas label.
The back box shall contain factory installed copper tube
extensions, 6" long and 3/8" OD to accept installer
furnished lines from the medical gas system. Each inlet
tube shall have a 1/8" NPT connection to accept pressure/
vacuum transducers.
The signal distribution and power supply board shall have
dual transformers and a selector switch to field select
either 115 volt or 230 volt primary service.
A
detachable fuse holder on the primary side shall be
included to insure that power is disrupted when the
transformer cover is removed.
The alarm audio tone shall be continuous. Its sound
intensity shall be 90 dBa at 2 meters. The audio signal
shall be cancelled only by the alarm silence button or fault
correction.
The audio alarm condition shall reactivate every half hour
until the fault has been corrected. Regardless of the audio
alarm, the LED shall indicate abnormal as long as a fault
condition exists. The alarm shall automatically reset with
the correction of the fault condition.
The panel shall be equipped with dry contacts for each
pressure/vacuum module. This will enable the alarm to
interface with another alarm or central computer system.
Gauge model area alarm panels shall be Chemetron®
Series 74-14-XXXX.
