S361MK - Mains Relay Kit
This kit is designed for switching a 240vac mains load of up to 5A operated by a 12vdc input from an intruder system. The 12vdc relay coil
is rated at 35mA. Two white plastic single gang enclosures are provided for segregation of the intruder alarm system and the mains
connections.
The first enclosure is tampered and contains a relay with single pole change over contacts rated 5A at 240vac or 12/24vdc. The relay coil
requires 12vdc to operate. An LED is also provided which illuminates when the relay is energised. The tamper switch is normally closed
and opens when the face plate is removed from the wall.
The second enclosure is purely a junction box which provides a replication of the SPCO contacts. An earth terminal is also provided for
convenient termination of an in coming mains cable. As the enclosures are all plastic, no earth connection is required. A loop of cable is
provided within the kit to connect the two enclosures together. This should be connected as shown below. Should the provided cable loop
not be used, an alternative 3 core cable of not less than 1mm should be used.
To operate the relay, apply 12vdc to the + and - terminals. The spring provided for the tamper switch needs to be pushed on to the tamper
switch before finally fixing the face plate in place.
The enclosures are supplied un-labelled. The decal (included) has a clear window 10mm x 46mm. The area under the decal is 12mm wide to
take standard labelling machine tape. The window is free from adhesive, nevertheless, it is wise to maintain cleanliness and avoid fingerprints on
the inside of the window. If a labelling machine is not available a paper label can be used and examples are given below complete with cutting
and folding lines. If the text you require is not shown here then it is a fairly simple matter to make one with a word processing or graphics
programme. The dimensions here are given to help you.
