Product details


A high quality, cost effective solution for powering two electric latch pullback exit devices.
  • Provides the necessary surge current that most latch pullback exit devices require.
  • Delivers the necessary in-rush current to power two latch pullback exit devices.
  • Independent inputs/outputs with priority sensing; with built-in delays each output harnesses the full capacity for the power supply.
  • Solid-state design eliminates mechanical problems associated with relays.
  • Thermal overload sensing reduces risk of failure due to overheating.
  • Fire alarm disconnect link.
  • Inputs triggered by dry contact.
  • Intelligent short circuit detection detects shorts much faster than glass or resettable fuses and isolates the short to the individual output.
  • Removable euro-style terminal blocks allow for easy wiring.
  • Efficient battery backup/charging circuitry with zero voltage drop at power loss (PS2BB)
  • Solid-state reverse polarity protection for battery connections (PS2BB)
  • Audible alert when sensing AC power failure & low battery (PS2BB)
  • Two solid-state inputs/outputs (input triggered by dry contact)
