Can anyone help please?
I am currently designing a lighting installation for a steel modular switchgear housing. The module is divided into three seperate rooms each with it's own light circuit. The module is classed as "Un-manned" and as such the client has requested using PIR Sensors in place of conventional light switches, in a bid to prevent lights being left on. Additionally he has asked for an override switch (clever man).
From researching on the net I dont think PIR's are the answer since maintenance engineers are liable to be stationary with in the module for long lengths of time and with the height of the installed equipment, complete coverage will be difficult to achieve. Personally I feel that the override switch is a non-starter, given the clients overall aim.
I am looking into using a "Delay off" switch on each circuit - to give maybe 8 hours light - and then automatically turn the lights off. However this is not a concept that I am familiar with and would welcome any advice anyone can offer.
