As a key specialist component supplier to the fire sprinkler industry in the UK, we buy (and sell) literally thousands of Bailey & Mackey 1381 LPCB approved pressure switches every year – most commonly 14 bar but also 4, 11, 28 and 42 bar…mainly non-V, but also V (variable differential). We have them all, so if this is something you need then you’ve come to the right place!
We are also often asked whether we offer these switches pre-wired for a DIN plug connection – some customers buy them as standard, some buy them when they are replacing old switches and want a like-for-like, some buy them because at certain sites they must be wired up only by an electrician (whereas swapping a pre-wired plug is quick and easy).
This is all good; however, some customers DON’T buy them for two reasons – 1, they are very expensive at around 3x the price of a standard switch; and 2, there is a very long lead time at around 10-12 weeks which is a problem when you have an old failed switch that you need to replace yesterday.
Well, as usual, SEP is here to solve your problems!
For any 1381 pressure switch that we stock (0.2-4 bar, 0.5-11 bar, 0.7-14 bar, 2-28 bar, 2-42 bar, both V and non-V), we can pre-wire for you and supply with plug – ready to despatch within 24 hours, if not the same day.
The connection and plug are DIN 43650 Form A (square), with 3 pins (COM, NO, NC) + earth, in accordance with Bailey & Mackey’s standard.
We are confident that you won’t find this level of stock availability and turnaround anywhere else.
