Automation & security

Networked I/O that runs the length of the building on one pair.

Optically isolated RS-485 to 4000 feet, with wiring fault and lightning protection, auto termination, and diagnostics on every module. The same network the SS4544 motion controller speaks.

Access control

ENTRY control keypad

Used to control access to secured areas — gate, door or barrier. Built for outdoors, with a key lock for maintenance and a network that survives a lightning strike on the run.

  • Weatherproofed aluminium case with UV-resistant epoxy paint
  • Key lock for maintenance access
  • 20 character, 4 line, wide temperature range backlit LCD display
  • 12 key backlit keypad with embossed rubber keys
  • Intercom speaker, plus room for a video camera
  • RS-485 optically isolated network with wiring fault and lightning protection
  • Two relays for gate control and auxiliary use
  • Beeper for audio feedback to the operator
  • RS-232 to RS-485 conversion
  • Optional card swipe reader
  • Infra-red box security detector
  • Pluggable screw terminal interface connectors

Multiplex input modules

SMX series — 16 to 96 inputs.

Pick the input count, decide whether you need the two onboard relays, and wire it back to the controller on a single twisted pair.

SMX16 / SMX32 / SMX48

Multiplex input modules in 16, 32 and 48 input sizes, with or without relays. The -R models add two SPDT 240 VAC 10 A relays. Supplied in a lockable steel weatherproof case with knockouts.

SMX64 / SMX80 / SMX96

The high-density range, for panels that need to bring a lot of contacts back over one pair. Same RS-485 network, same connectors, same diagnostics as the smaller modules.

SMX64 / SMX80 / SMX96 models
SMX96-R 96 inputs, 2 SPDT 240 VAC 10 A relays
SMX80-R 80 inputs with relays
SMX64-R 64 inputs with relays
SMX96 96 inputs, no relays
SMX80 80 inputs, no relays
SMX64 64 inputs, no relays

Common to every SMX module
