4. Alarms

4.1.  Gas Alarms

When an alarm set-point has been reached, the audible, visual, and vibrating alarms will activate

to alert the users. All gas alarms are configurable to meet the specific needs of users and only

operate once the monitor warm-up is complete.
An alarm can be either ‘latching’ or ‘non-latching’. A ‘latching’ alarm will remain active until reset

by the user by pressing and holding the 

R

 button after the gas readings have returned to a safe

level. A ‘non-latching’ alarm will reset automatically when the gas readings are safe.

4.1.1.  Flammable LEL Alarm

Two alarm levels, ‘HI’ and ‘HIHI’, are available.

4.1.2.  Oxygen (O

2

) Alarm

Three alarm levels, HIHI, LO, and LOLO, are available.

4.1.3.  Toxic Alarm

The monitor calculates the Short Term Exposure Limit (STEL) and Long Term Exposure Limit (LTEL) –

known as Time Weighted Average (TWA) readings – for each toxic gas range. Each toxic range

has STEL and LTEL alarms, in addition to HI and HIHI alarms.

In the following examples, 

Figure 25:

Figure 25:  O

 LOLO Alarm

NOTE: A  TWA  value is  the  mean gas  level exposure over  a specific period.  The

STEL is 15 minutes and the LTEL is 8 hours. Usually, TWA alarms mean the monitor is

for a single user. For multiple user applications, an option is available to reset the

STEL and LTEL after each monitor switch-off.
NOTE: All alarm levels – HI, HIHI, LO, LOLO, STEL, and LTEL – are factory set. The

user must set the levels in accordance with their  company’s procedures and  with

local health and safety legislation. Alarm levels can be changed via the monitor set

up menu.
