The Marconi Lifeguard is a maritime alarm receiver designed to automatically monitor distress frequencies for alarm calls from ships in distress. Up on receipt of an alarm, the unit will sound an alert in the radio room, the radio officer's quarters and on the bridge so that all necessary crew members are alerted to the distress.
The unit has not been powered up, from the pictures below it can be seen that there are some relays missing as well as a valve.
I have recently acquired a Lifeguard A/A similar to the one shown.
ReplyDeleteMine also has the relays missing as well as several valves. Do you have any information on the type of relays fitted to these?
Hi Jonathan,Interested to hear you have a Lifeguard, its an unusual piece of equipment outside marine/museum circles. However, I don't know exactly what relays were specified. They were all ( I think) 2 pole C/Over. They are listed in the manual with a Marconi works number, which might help with a bit of detective work. I'm sure a suitable relay could be found, it depends upon how original uou want to be! I haven't actually done anything with ours as yet as other projects have taken priority.
DeleteTh museum does have a copy of the manual for downloading, email me - michael@gb2mop.org - and I'll give you instructions for downloading.
