The economical CX-SA1 features a momentary or extended trigger, two relays and 3 timers. The CX-SA1 will properly sequence an operator and electric lock (any kind) or two doors that form a vestibule. and it becomes a latching relay with the flick of a switch.

Applications: Ideal for automatic doors systems that require a make/break relay, uni-directional door sequencing, or that require both momentary and maintained inputs. Provides latching output for connection to fire alarm (smoke EVAC) systems.

Features:
Sequence and release
Sequence and hold while voltage still applied
Sequence and hold till next trigger
Triggers for sequencing and hold open applications
Dry contact and/or hot trigger input on either trigger
Stuck momentary trigger leaves the extended trigger functioning
Noise filtering on the triggers to prevent false activations
2 relays for controlling external equipment
Visible indicators for status of timers and relays
