Lowell SCS8R-ASM
8-Channel Rackmount Power Sequence Controller (with Alternate Sequence Mode)

SCS8R-ASM

Lowell's SCS8R-ASM rackmount sequencer provides time-delayed activation and de-activation of equipment with Alternate Sequence Mode (ASM) capabilities.  The unique Alternate Sequence Mode provides the opportunity to bypass selected outputs for alternate applications such as regularly-scheduled rehearsals and other events where all sequenced equipment is not necessary.  As with other Lowell sequencers, the SCS8R-ASM is typically utilized in conjunction with Lowell’s Remote Power Control Series RPC which is available separately in rackmount or vertical strip styles and with Lowell’s RPS Series switches (also sold separately).

This slim, 1RU sequencer mounts in minimal space to sequentially activate equipment that is connected in the same rack or in remote locations.  Sequence operation is initiated by a front rocker switch.  Clearly marked and color-coded LED's provide visual status of connected equipment and a front adjustable delay allows 0.5-10 seconds between steps.

The SCS8R-ASM provides eight rear access control outputs (barrier strip), a rear programmable dip switch for alternate sequence operation, and an alarm interface for use where required by local building code.  Each of the eight control outputs include switch contacts for connection to remote power control-activated equipment and auxiliary dry contacts for the sequential activation of accessory systems such as projector screens, lighting, blinds, etc.

To sequentially activate RPC connected equipment, each switch output contact (common, switched relay) is connected via 2 conductors to an RPC Series remote power control (sold separately) and then to the equipment to be sequentially activated.  Each output can be connected to one remote power control with a single piece of equipment or may be connected to up to ten remote power controls, in daisy chain format, with multiple pieces of equipment each.

To sequentially activate accessory systems and/or indicator devices, each control output includes auxiliary contacts (normally closed, common, normally open) with a rating of 5A for connection to peripheral devices.

The sequencer is equipped with a front mounted rocker switch for sequence activation.  Optional switches for remote activation may be connected to the terminal block on the rear panel.  Up to 8 switches may be connected in parallel.

To utilize the sequencer in Alternate Sequence Mode (ASM) whereby selected outputs are bypassed for partial system operation, two things must be done. First the the 'Sequence Step Bypass' termination block on the rear panel needs to be set on or off for each of the eight steps.  Additionally, a separate ASM-style remote switch (sold separately) needs
to be installed to activate the alternate sequence operation.  (Note: The dry contact may also be activated using devices by others including Crestron and AMX).
