Area Line Pressure
Alarms Features

Primary power design accepts 115 or 230 AC volt (50/60 Hz).

Individual display indicates pressure/ vacuum at all times.

Alarm module calculates high and low alarm automatically (20% above and below normal line pressure)

One LED on each module indicates normal (green) or abnormal (red) gas line pressure status at a glance.

Local or remote (up to 5,000 ft.) pressure sensing.

Area alarms can monitor up to 6 medical gas or vacuum services.

UL and CSA listed

Specifications

Area alarm panels shall be designed to meet the requirements of NFPA and CSA standards. Alarms shall be U.L. and CSA listed as an assembly and shall include all necessary gauges, factory wiring, transformers and circuitry requiring only 115 or 230 AC volt primary power. Internal voltage shall be stepped down to 5 DC, and DC, control circuit power. Voltage to external pressure or vacuum transmitters will be 20 DC.

Area alarm panels shall be modular in design and have one LED to indicate each
normal/abnormal condition. Each gas monitored shall have a 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 a 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, LCD window, and a window for the gas label.

The back box shall contain factory installed copper tube extensions, 6' long 1/4" ID flared to 3/8" ID to accept installer furnished lines from the medical gas system. Each inlet tube shall have an internal check valve and female quick connect coupling to accept pressure/vacuum transmitters.

The signal distribution and power supply board shall have two circuit breakers on the secondary side of the circuitry. It shall also contain dual transformers and selector switch to field select either 230 or 115 AC 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. The sound intensity shall be 90 dBa at 2 meters. The audio signal shall be canceled 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 can be equipped with dry contacts for each pressure/vacuum module. This will enable the alarm to interface with another alarm or central computer system.

Master/Slave Alarms
Non-Gauge Features

Primary power design accepts 115 or 230 AC volt (50/60 Hz).

Normally open or normally closed circuitry is available

Non-gauge alarm can monitor up to 48 signals.

Audio alarm periodically reactivates if the alarm condition is not corrected.

UL Listed and CSA Certified.

Specifications

Non-Gauge model master/slave alarm panels shall be designed to meet the requirements of NFPA and CSA standards. Alarms shall be U.L. Listed as an assembly and shall include all necessary factory wiring, transformers and circuitry requiring only 115 or 230 volt primary power. Internal voltage shall be stepped down to 5 volt and 20 volt, control circuit power.

The master/slave alarms shall include one or more eight signal annunciator modules for wiring to remote switches. External switches may be either normally open or normally closed type, or, if more than one eight signal annunciator module is used, both can be used. The selection of NO or NC is selected at SETUP and is set per module. Factory setup shall be for closed circuitry wiring.

Each signal shall be labelled for its function using self adhesive labels provided with the unit. Adjacent to each signal label will be a red LED indicator light to signify condition of the external switch. Activation of any switch will illuminate its LED and actuate the audio alarm.

The 8 signal annunciator module shall contain an independent normal/abnormal LED (green for normal and red for abnormal).

The Control Module shall have a test switch and an alarm silence switch. The test switch shall test all modules one at a time. There shall also be a LED on the Control Module to indicate status of the micro-controller (green is normal, red for a malfunction).

The front panel shall have a window for installing an area designator. The back box shall contain a master circuit board with two circuit breakers on the secondary side of the circuitry. It shall also contain dual transformers and selector switch to field select either 230 or 115 AC 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. The sound intensity shall be 90 dba minimum. The audio signal shall be canceled only by the "alarm silence" button or fault correction.
The audio alarm condition shall reactivate every 8 hours 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 will be equipped with dry contacts for remote signal. This will enable the alarm to interface with another alarm or central computer system.
