Introduction to MINIPLEX Systems
Overview The 4100 MINIPLEX Fire Alarm System uses transponder cabinets containing remote
interface cards (RICs) to extend power and communication across large areas. MINIPLEX
transponders allow the system to provide applications for up to 1000 monitor and/or control
points and 2000 annunciator points (see note). Using 4100-style serial communications, up to
31 distributed MINIPLEX transponder locations are possible for initiating device circuit cards,
MAPNET II/ TrueAlarm addressable communications interfaces, notification appliance circuit
cards, LED/switch controls, auxiliary relay control cards, power supplies, and audio amplifiers.
By selecting the required combinations of modules and mounting MINIPLEX transponders at
the appropriate building locations, wire quantities are significantly reduced for all monitor and
control functions. Since power for the local modules is provided from the local power supply,
the wiring from the control panel need only be separate twisted, shielded pairs for data, voice,
and telephone.
Notes:
• One point consists of one LED or one switch on an LED/switch module, one LED driver output on a
graphic driver, or one switch input on a graphic switch input module.
• Up to 32 modules can be controlled by one MINIPLEX transponder.
• The 4100 0117 MINIPLEX Expansion Power Supply is available with a power-limited 8 A output.
