electric strike

Controlled keeper

Record the evidence that the device releases at the strike rather than retracting a door-mounted latch or holding an armature magnetically.

1. Which component changes position or restraint when the strike is electrically actuated? definition
2. Which retaining and retracting functions belong to the mating lockset or exit device? boundary

Engagement envelope

Capture mounting dimensions, handing and latch or bolt geometry as a combined fit assessment.

1. What frame cutout, mounting depth, keeper opening and latch engagement dimensions are required in mm? measurement
2. Does the documented compatibility cover the actual mating hardware, handing and any auxiliary deadlatching feature? boundary

Supply and duty

Record permitted supply characteristics, current demand and energisation limits.

1. What voltage, AC or DC supply, polarity and actuation or holding current does the documented configuration require? measurement
2. What energisation duration, duty cycle and wiring requirements must the controller and power supply satisfy? action

Power loss and reset

Describe loss-of-power behaviour, release timing and the conditions for restoring retention.

1. What does the keeper do when power is applied, removed or interrupted in its current configuration? definition
2. After a release command ends, what keeper movement or door cycle is required before the mating latch is securely retained again? action

Retention and preload

Record strength and release-under-load evidence with their distinct test conditions.

1. What retention-force and endurance ratings are documented, and under which test methods and mounting conditions? provenance
2. What load on the keeper is permitted during release, and what preload is present at the installed opening? measurement

Feedback meaning

Distinguish keeper position, latch presence, controller output and independently observed door position.

1. Which physical condition does each available monitoring contact detect, and how is its electrical output interpreted? definition
2. Which claims about secure latching or door closure require evidence beyond the strike's own monitoring signals? boundary

Egress and emergency interface

Identify how the installed strike interacts with the opening's exit hardware and required emergency responses.

1. How can occupants operate the mating lock or exit hardware while the strike remains retaining, including during power loss? boundary
2. Which required emergency responses affect this strike, and what authorised integrated test demonstrates them? action

Approval evidence

Capture applicable issuing bodies, standard editions, certification records and limitations on installation.

1. Which standards and issuing bodies govern this application, and which current records demonstrate the exact product's claimed ratings or listings? provenance
2. Do the permitted frame preparation, mating hardware, power-loss configuration and environmental limits cover this installation, including any fire-rated assembly requirements? boundary

Release and latching faults

Record symptoms and discriminating checks for failure to release, failure to retain or intermittent operation.

1. During a failed operation, what voltage reaches the strike, what does the keeper do, and where does the mating latch contact it? measurement
2. Which documented checks distinguish inadequate power, excessive preload, misalignment, obstruction and an internal mechanism fault? action

Permitted service and verification

Link cleaning, adjustment, lubrication where specified, and component replacement to manufacturer instructions and functional checks.

1. Which service actions and replacement parts are explicitly permitted for this strike, and which instructions establish those limits? provenance
2. What checks of latch engagement, retention, commanded release, power-loss response and monitoring must pass before the opening returns to use? action
