Help with cira 1974 equipment |
|
|
I'm looking for help in getting an old piece of alarm equipment to work, its
not for an installation its just for my perverse fun.
I have an old Chubb panel with a PCB marked 4220 MKIV, this unit give out
3,54Hz and 11.16Hz (not sure which is normal or alarm mode) down a GPO pair
to a alarm receiver.
The alarm receiver is type normally fitted into Police stations years ago,
it has a GPO type toggle switch with indicator lamps for reset, alarm and
line fault.
Anyone out their with any info?
Thanks
Ian

Try Chubb themselves for info' on this. They are normally quite helpful on
older equipment. An e-mail explanation to their support guys might give you
more to go on. |
