Camden Door Controls CX-SA-1 switching network is an economical door interface relay. Relay 1 has an adjustable delay on release of 0 – 30 seconds. Relay 2 has a delay on operate of 0 – 30 seconds, and delay on release of 0 – 30 seconds.

Product specifications
Low-voltage wiring	Required
Basis	Structured, independently qualified product connection evidence
Preparation	The unit mounts with double-sided foam tape and is a small wrap-around-sleeve module about 3/4 in (19 mm) deep, per the datasheet. Neither document states an explicit site preparation requirement, such as a box, cutout or prepared surface. Preparation is not determined from this evidence.
Electrical	The SA-1 is powered from 12 through 24 Volts, AC or DC, with no input polarity. Identify the delivered terminals by their labels: lock and operator relays each have C, NC and NO; inputs include +OUT, momentary trigger, extended trigger and GND REF. The momentary dry-contact circuit closes +OUT to MOM TRIG; the extended dry-contact circuit closes +OUT to EXTENDED TRIGGER. A powered trigger instead uses the corresponding trigger input and GND REF; its allowed range must match the actual board revision. Select dry or powered inputs for the intended interface rather than adding alternatives as extra cable runs. Each selected low-voltage input/contact loop needs two external conductors. The supplied MOV is local suppression across the lock relay contacts, not an additional field cable run. The manual combines MK5 and MKIV-labelled drawings with different terminal order, so follow labels on the delivered unit. Set lock, delay and operator timing and the selected latching/extended behavior, then test it. Choose field cable specification and routes for the actual circuit.
