I was recently watching a video posted by user kcin556 about a coded pull station which I have. The question is how do I wire up the supervisory circuit on the coded pull to pulse the strobes and horns separately? My pull station does have a supervisory contact. Thanks for any help.
On the rear of the station you have 5 wires: two grey, a red, yellow, and blue. The two grey wires connect to the supervisory contact, which was intended to be used as a reminder for building facilities staff to replace the break-glass rod on the station. The contact closes when the station is pulled, and resets when the break-glass retainer is opened with a hex wrench.
Although not the intended use, I like to use this contact to activate any strobes/lights connected to my coded stations so that they can operate without receiving the coded pulses. The contact can be wired into the strobe circuit just like any normal switch by connecting the two grey wires in series with the circuit.
Here’s the video firefreak57 was referring to. Notice how the light remains on until I open the glass-rod retainer, resetting the supervisory contact and shutting off the light.
