Pilot Dual Gas Alarm
This is the Mini Gas Alarm's big brother. It has all the features of the Mini, but with the added benefit of two sensors on 3.5 meters of 3-core cable. The Dual Gas Alarm, or Twin, has been recently redesigned with some useful extra features:
It has been given an extra terminal on the board so that a relay can be added to activate the blower fans in the event of an alarm.
This extra terminal can alternatively be used as a network terminal to allow any number of Dual Alarms to be 'chained' together. This is particularly useful on larger vessels as it allows you to have a Control unit and at least one detector in most rooms, yet if the unit at the other end of the vessel alarms, all the units will activate. The unit that detected the original leak will be identifiable by a bright LED.
The twin is designed for use with a 12/24 volts supply and draws 180 milliamps at standby, rising to 210 milliamps in the event of an alarm.
Dimensions: 35mm x 65mm x 120mm
