Engineer Resistor Kits for Fire Alarm and Security Systems.
Our handy Engineer Resistor & Relay Kits are specifically designed for use in fire alarm and security systems, providing all the essential resistor values required by most popular fire and security systems. The Fase resistor kits include high-quality, 1% tolerance YAGEO MFR-25 series resistors, rated at 250 mW, ensuring reliability and precision in all applications.
Perfect for professionals in the fire and security industries, our resistor kits are organised for convenience and supplied in a durable plastic compartment box.
Our Resistor and Relay Kits are available in 3 different kits, with each kit containing a selection of different resistor values, diodes, or relay modules as detailed in the below table.
All resistors are from the YAGEO MFR-25 range and are rated at 250mW with a tolerance of 1% making them ideal for use in the fire alarm and security system industries.
Each resistor kit contains approx. 30 of each resistor value, approx. 20 x 1N4004 (where included) and approx. 300mm of heat shrink tubing (where included).
