4.2 AUDIBLE ALARMS

The SCOTT INSTRUMENTS MINI-SA has an audible alarm which is acti- vated when any of the following conditions occurs:

-The preset gas alarm level is exceeded (ALARM)

-The Time Weighted Average (TWA) is exceeded

-The Short Term Exposure Limit (STEL) is exceeded

-The battery is exhausted

-The sensor is missing or incompatible

In addition, each time the instrument is turned ON, the audible alarm will pulse three times.

The following describes the function of the Audible Alarm during the alarm conditions listed above:

GAS ALARM – The Audible Alarm sounds when a gas concentration is de- tected that exceeds the chosen alarm level, or when a TWA or STEL alarm value is exceeded. A repetitive pulsing tone will occur at one (1) second intervals while the alarm condition exists.

In the LATCHING alarm mode, selected in the Alarm Setpoint Menu, after an alarm condition has cleared, the alarm indication will continue until the alarm is acknowledged by depressing a pushbutton. In the NON-LATCHING alarm mode, all alarm indications clear when the alarm condition clears. In either mode, the instrument gives an “all clear” signal with three audible beeps, three flashes of the Red Alarm Light, and three vibration pulses when the alarm indication is cleared.

When an Audible Alarm sounds, depressing either pushbutton on the instru- ment will silence the Audible Alarm for thirty (30) seconds. If the original alarm condition still exists after the thirty (30) second silence period, the Audible Alarm will sound again. The Audible Alarm can be silenced repeat- edly by depressing a pushbutton.

LOW BATTERY – An Audible Alarm tone will pulse once every fifteen (15) seconds to indicate when less than 10% of battery life remains.

MISSING SENSOR – The Audible Alarm for a missing or incompatible sen- sor is identical to the pulsing one (1) second tone that occurs during an ALARM condition. Depressing a pushbutton to acknowledge the condition turns the unit OFF.

PORTABLE GAS DETECTION INSTRUMENT specifications

The Energizer Portable Gas Detection Instrument is an innovative device designed for the safety and convenience of users in various environments. It is specifically engineered to detect hazardous gases, offering a reliable solution for industries such as oil and gas, waste management, confined space entry, and emergency response.

One of the primary features of this instrument is its multi-gas detection capability. Equipped with advanced sensors, it can simultaneously monitor a variety of gases, including hydrogen sulfide (H2S), carbon monoxide (CO), methane (CH4), and oxygen (O2). This versatility makes it indispensable for workers who are exposed to potentially dangerous atmospheres, providing real-time data to help ensure their safety.

The Energizer Portable Gas Detection Instrument employs state-of-the-art sensor technologies, including electrochemical, catalytic, and infrared sensors. Electrochemical sensors are particularly effective for detecting toxic gases with high sensitivity and low cross-sensitivity, making them ideal for use in confined spaces. Catalytic sensors are used for combustible gases, providing a consistent and accurate reading of gas concentrations, while infrared sensors offer a non-contact method for measuring hydrocarbons and other gases, enhancing the safety profile of the device.

This instrument is designed with user-friendliness in mind. It features a large digital display that provides clear and concise readings, allowing operators to quickly assess gas levels even in low-light conditions. Furthermore, the instrument includes audible and visual alarms that alert users to high gas concentrations, ensuring prompt response in emergencies.

Durability is a key characteristic of the Energizer Portable Gas Detection Instrument. Built to withstand harsh industrial environments, it is often housed in rugged, IP-rated enclosures that protect against moisture, dust, and impacts. This ruggedness is complemented by a long battery life, which ensures that the device remains operational during extended periods of use.

In addition to its physical capabilities, the device also offers advanced connectivity features. Many models come equipped with Bluetooth or Wi-Fi capabilities, allowing for remote monitoring and data logging. This function is particularly useful for compliance purposes, enabling employers to maintain accurate records of gas exposure levels over time.

In summary, the Energizer Portable Gas Detection Instrument combines advanced sensing technologies, user-friendly features, durability, and connectivity, making it an essential tool for promoting safety in environments where gas hazards may arise. It stands out as a reliable choice for professionals committed to ensuring a safe working environment.
