    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)
