I love the alarm but in the instructions it says once pulled activated will show in yellow it was never yellow and I was fuming but it’s good

My son has been fascinated with fire alarms ever since his first fire drill at school. To satisfy his curiosity I decided to build him his own fire alarm. I bought a cheap siren/strobe and this pull station and connected them with a couple op-amps and a relay in lieu of a $1500 control panel.So, the inside of this thing is a 4-way bridge rectifier. Even though there is a “+” and a “-“, it wouldn’t matter if you were to wire it backwards. The circuit is open normally, and basically passes through 2 diodes, a red LED and 1k resistor when pulled. I didn’t want to dim that LED (it’s visible externally when pulled) so I connected a 100 ohm resistor in series and amplified the voltage drop across that 100 ohms up to the point where it could switch a relay and drive the strobe. My son is happy, and this pull station worked well for me. Unfortunately I can’t tell you how it would work with a proper control panel.

Lo compré para un cuarto friki y la verdad es que está genial. Eso si, depende de la idea que tengáis, dado que es un interruptor de incendios real... necesitaréis quebraros más la cabeza xd

Great piece of kit. Much easier than pushing plastic.

I put this on a piece of wood with the siren and LED strobe light just so I can pull it any time I like for the fun of it! It works real good wires up great I have it hooked to 4 18650 batteries with a charge on it to keep it charged it is just used at a toy, but if you were replacing one of yours with it, it works great easy install has two keys. Has Loop in connections for power and to hook up another to another unit else where. very easy pull time and easy to reset if you have the key. Worth buying and I would consider buying another one!
