Elmdene

Elmdene, part of Potter, is a UK maker of power supplies for security and fire systems. This page lists the Elmdene products JEM Systems UK carries, most of which are power supply units, alongside sounders, door contacts, panic buttons and extension speakers.

The power supply range falls into several families:

• GEN2 and GEN3 12V DC switch mode units for intruder alarm systems, with housed versions that reference EN 50131-6
• STX series 24V DC units for fire systems, described on the product pages as EN54 certified
• TR series 24V door retainer supplies
• VRS 12V DC supplies, from plug-in 1A units to 8-output CCTV boxes
• Multi-access supplies with fused output modules, for access control installations

Before choosing a unit, work out the following:

• the voltage your equipment needs (12V or 24V DC)
• the total load current, plus the battery charging current
• the maximum battery size the enclosure can hold
• the number of fused outputs required
• whether the application calls for a specific standard, such as EN54 for fire
