Satel DG-1 Series Manual

DG-1
DIGITAL GAS DETECTORS
The DG-1 detectors are designed to detect dangerous concentrations of:
– carbon monoxide,
DG-1 CO
DG-1 LPG – propane-butane gas,
– natural gas (methane),
DG-1 ME
DG-1 TCM – soporific gases (e.g. chloroform vapors).
The detectors are intended to be used as part of a security system. This manual applies to
the detectors with electronics version 2.0.

1. Features

 Digital algorithm of gas detection.
 Digital temperature compensation.
 Prealarm feature (DG-1 LPG and DG-1 ME only).
 LED for optical signaling.
 Sounder for acoustic signaling.
 Supervision of gas sensor (not applicable to DG-1 CO) and supply voltage.
 Tamper protection against cover removal.
