Linear 2500-2589 365-Day Programmable Timer for Gate and Access Control Systems
The Linear 2500-2589 is a 365-day programmable timer intended for scheduling functions in select gate operator and access-control installations. In practical use, a timer can allow a gate, relay, or access-control circuit to follow programmed schedules such as business hours, holiday schedules, service access windows, or recurring control events. A 365-day timer is useful where a simple daily or weekly timer does not provide enough calendar control. Correct application depends on how the timer is wired into the control circuit and what the operator or access system expects from the timer output. The timer should be treated as a control accessory, not a safety device, and it should never be used to defeat monitored photo eyes, gate edges, stop circuits, or required UL 325 safety functions.

Technician Note
A timer can create scheduled commands, but it does not replace proper access-control logic or safety monitoring. Review the site operation carefully before adding or replacing a timer.
Before Ordering
- Confirm the system requires a 365-day timer rather than a seven-day or simple event timer.
- Check the original part number or system drawing for 2500-2589.
- Verify input power and relay/interface requirements.
- Confirm the enclosure and environment are suitable for the timer location.
- Review scheduled gate operation so the timer does not create unsafe unattended movement.
Important Ordering Warnings
- Do not use a timer to bypass safety devices, stop circuits, photo eyes, or gate edges.
- Timer wiring should be performed by a qualified technician familiar with the operator control circuit.
- Not every Linear operator accepts the same timer wiring arrangement.
Professional Advisory
For any high-voltage motor, drive, timer, or hardwired intercom service, use a qualified gate or access-control technician. After replacement, the complete system should be tested for normal operation, safe stopping, proper limits, and active safety devices.
Product Questions and Answers
What is the Linear 2500-2589 used for?
It is a 365-day programmable timer used for scheduling control functions in select gate operator and access-control systems.
How is a 365-day timer different from a seven-day timer?
A 365-day timer can support longer calendar-based schedules, such as holiday or annual programming, while a basic seven-day timer is typically limited to weekly patterns.
Can this timer hold a gate open during business hours?
It may be used for a hold-open or scheduled control function if the operator wiring diagram supports that use and all required safety devices remain active.
Is this a safety device?
No. It is a scheduling/control accessory and should never be used as a substitute for monitored entrapment protection or safe gate operation.
What should I verify before ordering?
Verify the timer part number, power requirements, relay/interface needs, enclosure location, and the way the timer connects to the operator or access-control panel.
