Frequently Asked Questions
- What does preload mean on an electric strike?
Preload refers to pressure applied to the latch by the door, often caused by air pressure, seals or misalignment. The KES900Z can release electrically under up to 35 kg of this pressure. - Can the fail mode be changed on site?
Yes. The strike can be configured as fail safe or fail secure during installation. - Is this electric strike suitable for fire doors?
No. The KES900Z is not fire rated and must only be used on non fire-rated doors.
Additional Information
- This model is commonly selected where door seals or air conditioning create resistance against the latch.
- Zinc alloy construction makes it a cost-effective alternative to stainless steel strikes.
- Monitoring outputs allow integration with access control systems for door status feedback.
