Description

DETECTOR GAS NATURAL Y PROPANO CON RELAY DE ALARMA Y FALLA ALIMENTACION DC 12/24V

Natural/Propane Gas detector with Alarm relay output and Trouble relay output, DC 12/24V

MARCA: FIRESTAR
MODELO: DGNP701-R2

AC/DC gas alarm

UL 1484, UL 2075, Catalytic gas alarm datasheet

Description
DGNP701 AC/DC gas alarms are mains powered
combustible gas detectors that can be powered directly
from the mains supply (with AC adaptor enclosed) or from
a DC 12/24 V supply (such as a security system).
Advanced electronics in conjunction with a catalytic gas
sensor provide accurate early detection of natural gas or
propane gas and high immunity against unwanted alarms.
The NB701 range of gas alarms provide home owners
and installers with an easy-to-install, economical solution
for life safety and property protection applications.

Features
The DGNP701 gas alarms include a wide range of standard
and optional features to suit many applications.
• Advanced algorithms provide advanced detection
discrimination
• Highly accurate detection of LNG and LPG
• Stable gas sensing chamber. No adjustment or
replacement required
• High immunity against unwanted alarms
• Dual function action button to temporarily silence
unwanted alarms (Hush), and to verify battery and
alarm operation (Test)
• Low power consumption
• N/C or N/O alarm and trouble relay output models
available
• DC12V/24V applicable without adjustment
• Optional 110V/220V AC adaptor interface available
• Loud alarm sounder output > 85dB @ 3m
• Product trouble alert
• 5-year End-of-life alert
• Separate indicators for Power, Alarm and Service
• Easy installation. No programming required
• Low maintenance
