Call Registration Signal Unit

Model CR

Cost-efficient illumination for call and hall buttons

Many vintage elevator systems require the addition of in-car and hallway button lighting to comply with the National ADA Code and to enhance passenger interface. Owners of such older elevators have traditionally faced extensive wiring upgrades, significant labor charges and lengthy equipment downtime to accomplish this upgrade.

Electrodyn’s innovative Model CR provides illumination to existing car and hall buttons in elevator control logic systems not originally manufactured with this feature. When a common signal for the call registration lights is introduced into the hall riser and/or car station, call registration can utilize existing wiring—even for 24VDC fixtures. Model CR is available with a special enclosure to facilitate mounting in close proximity to selector-mounted call relays. Installation time is minimal because the addition of new hatch wiring is unnecessary.

Key features:

• Compatible with Otis elevator latch relay call logic and 24VDC fixtures.
• Reuses existing input wiring for acknowledgement signals—even for 24VDC fixtures.
• Average labor time (determined by direct field feedback) is 4 hours.

Interface

By reusing existing input wiring, Electrodyn’s unique Model CR radically reduces installation time to offer more value for your investment. Installation is accomplished with two series connections to each relay. Adaptable to all voltages, a set of parallel connections is made to the primary power source to supply energy to the Model CR. If 24VDC fixtures are used, Model CR provides the source voltage.

The Call Registration Signal Unit is also available in an enclosure to facilitate mounting in close proximity to call relays. Model CR is only one of Electrodyn’s many innovative products to help you modernize your elevator system.
