The Edwards 4-24L18S-E is a control-display module for the Edwards EST4 life safety control platform, EN54 compliant version, with 24 LED indicators and 18 control switches. It fits the inner door of EST4 control panels and remote annunciators to give easy-to-use controls and at-a-glance status.
Each of the 24 indicator positions is made up of five individual LEDs (red, yellow, blue, green and white). The colour and flash rate of each indicator are set at configuration time, so one module can show, for example, zone alarm, disable and trouble status, or damper, fan and audio zone status.
