2. Features

The LDM250, LDM450 and LDM650 are central units with two/four/six channels(sensors).

The LDM250/450/650 is a multi-channel microprocessor-based gas monitoring system. Each, up

to a maximum of six channels, can be individually configured to monitor different gases with up to

three alarm concentrations all with status LEDs.

Other features include:

- User configurable alarm time delays

- Manual/auto alarm reset for each channel

- Built-in service function and self-test program

- Four alarm relays with 230 volts rated SPDT contacts

- Failsafe relay operation on power loss

- Audible alarm

- Low voltage output for auxiliary alarm indication.

Please Note!

The LDM250, LDM450 and LDM650 are normally supplied with default set alarm

thresholds. These must be verified or reset during commissioning. Alarm levels

must always be set on each channel for proper gas and detector type.

Default settings from factory:

Alarm level

Offset

Alarm C

1,0V

Alarm B

2,0V

Alarm A

3,0V

Alarm levels, factory settings are:

HFC, HFO, HCFC (ppm)

C=100

B=1000

A=2000
