55 Series 3-4 Latchbolt Electric Strikes
SDC’s 55 series 3/4” latchbolt electric strikes are heavy duty, designed for
installation in hollow metal frames for access control of cylindrical
locksets, mortise locksets with or without deadbolts and mortise exit devices.
55 series strikes accept 3/4” throw latchbolts and up to 1” throw deadbolts.
The choice of six application faceplates eliminates the need for centerline
relocation, making them ideal for new or retrofit, high security access
control applications.
55 series strikes retrofit existing ANSI 47/8” strike prep – no centerline
relocation required.

COMPONENT CONSIDERATIONS
LOW ENERGY OPERATORS
CLICK TO VIEW SDC’s low
energy swing door operators are designed for applications requiring ADA
compliance, user convenience and touchless solutions. The state-of-the-art
microprocessor-based operator is self-tuning and selflearning while offering
non-handed operation,
full mechanical stops, door sequencing and a variety of interface options for
sensors, push-plates, fire alarms and electrified locks. A built-in 1 Amp
power supply allows users to power electric latch retraction directly from the
operator.
PUSH PLATES & PANELS
CLICK TO VIEW SDC’s push plates and panels combined with SDC’s operators,
bollards and locking devices allow for complete access and egress solutions
for ADA compliant applications. Included are round and square push plates, as
well as wall mount and full-size push panels. All types can be wireless or
hardwired, bollard or wall mounted. ADA compliant solutions work seamlessly
with low energy swing door operators like Auto EntryControl™.
EXIT SWITCHES & SENSORS
CLICK TO VIEW
SDC offers a variety of exit
button and push button styles and contact configurations to fit several
requestto-exit application needs. Additionally, SDC’s wave-toopen switches and
motion sensors provide hands free compliance and convenience for touchless
applications using proven infrared detection technology. A simple wave of the
hand in front of our touchless switch models activates the switch to control
electric locks/strikes, magnetic locks or automatic door operators for entry
or egress.
KEYPADS & READERS

SDC has a variety of digital keypad and proximity card access control system
equipment to meet any need. SDC’s keypads and readers are engineered to
provide real-world door control of a single opening up to 100 doors, such as
indoor, outdoor and PC-based systems, while ensuring fire and life safety code
compliance along with superior expandability and flexibility in authorization
identification, authentication, access approval and accountability of entities
through login credentials.

access controls and electric locking hardware. They are UL listed and provide
filtered and regulated linear DC power, with optional control logic, component
interface, alarm interface and battery back-up to meet the requirements of
single and multiple accesscontrolled openings. The circuitry design is ideal
for the inductive loads generated by access control hardware for high
performance and longevity.
