Which access control technology uses a microchip and antenna embedded in a card or key fob that communicates wirelessly with a reader to grant gate access?
Answer: RFID (Radio Frequency Identification)
RFID credentials contain an embedded chip and coil antenna that transmit a unique ID to the reader wirelessly when in proximity, allowing contactless gate access.
When integrating an access control system with an automatic gate operator, the access control device typically signals the operator to open via:
Answer: A dry contact relay output (momentary contact closure)
Access control panels output a momentary dry contact closure (like a push-button signal) that connects to the gate operator's trigger input terminals to initiate opening.
A 'fail-safe' gate lock configuration is defined as a lock that:
Answer: Unlocks (releases) automatically during a power failure to allow egress
Fail-safe locks are de-energized to lock and energized to hold unlocked, so any power loss releases the lock — used where free egress during emergencies is the priority.
A telephone entry system installed at a gated community entrance allows visitors to:
Answer: Contact a resident who can then remotely release the gate via their phone
Telephone entry systems dial a resident's phone number; the resident can speak with the visitor and then press a key tone to trigger a relay that opens the gate remotely.
What is the standard power supply voltage for most residential automatic gate operators installed in the United States?
Answer: 120V AC
Residential gate operators in the U.S. are predominantly powered by standard 120V AC household current, though the operator's internal electronics may step voltage down to DC for control circuits.
When installing underground electrical conduit for an automatic gate operator, which conduit type is commonly required per the National Electrical Code (NEC)?
Answer: Rigid PVC Schedule 40 or Schedule 80 conduit
NEC requires underground electrical runs to be in rigid nonmetallic conduit (PVC Schedule 40 or 80) or rigid metal conduit to protect conductors from physical damage and moisture.
A 'fail-secure' lock configuration on a gate means the lock will:
Answer: Remain locked during a power failure, maintaining the secure state
Fail-secure locks are energized to unlock and spring-loaded to lock, so a power failure causes them to remain in the locked position — used where security takes priority over free egress.
