I look after a three story office block on a local industrial estate one morning a week. Owners live miles away in Worcestershire.
Previous maintenance guy left under a cloud 4 months ago, taking all the information, records & many of the keys with him - leaving the owners (& me) completely in the dark.
Got a call from one of the tenants on Friday, there was an alarm sounding loudly on the unoccupied ground floor.
Finally traced it to a keypad inside one of the unoccupied offices. Instructions said "enter pin to reset".
Took a flying guess that it might be 1234 - and it was! Silence reigns!
Called the owners, nobody knew anything about it, must have been install by the previous tenants - Medway Chamber of Commerce - who bizarrely went skint just under a year ago.
Back there today fixing the front door lock when a Chubb Alarms van pulls up, guy asks me where the Medway Chamber of Commerce was. Annual service on the alarm!
Had I been anywhere else in the building he would have tried the entry phone, got no answer & gone!
Somebody up there was looking after me.
