Description

Linear heatwire temperature detectors in automatic fire detection & alarm system use a couple of resistors in order to detect short circuit and open circuit conditions. This results in an acceptable range for an idle circuit or sensor and another range for activated circuits. This LHW simulator allows for easy switching between those resistance values.
Additionally, it can operate with ‘hard’ input voltages up to 24V for limited duration (1 minute) and is protected against inadvertent application of mains voltages. This protection resets automatically.
Wires are connected via spring loaded binding posts.
