Simplex 4100-7401 is a 24 point I/O graphic module, an interface module for LED and switch control of custom graphic annunciator panels. Each of its 24 points can be set as either a switch input or a lamp/relay driver output, so one module can read panel switches and light graphic indicators at the same time.
Switch inputs can be unsupervised, supervised for opens, supervised for opens or shorts, or set for supervised monitoring of hand/off/auto (HOA) switches, and the switches can be momentary or maintained, two or three position. Driver outputs are supervised for open circuits and can be on steady or pulsed slow or fast. The module also has inputs for a remote power supply trouble and for lamp test.

FAQ
What can each point be used for?
Each of the 24 points is selectable as either a switch input or a lamp/relay driver output.
How much can each output drive?
Each LED/lamp/relay driver is rated 150 mA at 24 VDC, with current-limited inrush, up to 600 ft (183 m) or 2 Ω from the module.
Which panels support it?
Simplex 4007ES, 4010ES, 4100ES and 4100U fire alarm control units. It is not compatible with installed 4020 Series panels.
Can it monitor HOA switches?
Yes. Switch monitoring includes unsupervised, supervised for opens, supervised for opens or shorts, and supervised monitoring of hand/off/auto switches.
