SECO-LARM E-9680-10B25 IR Curtain Sensors for Indoor/Outdoor Access Control, 25ft
The SECO-LARM E-9680-10B25 is an older 10-beam infrared curtain sensor designed to create a dense vertical detection pattern across a protected opening. The 10-beam format was commonly used where the opening was too tall or too security-sensitive for a single photobeam, such as a doorway, window line, fence-top area, skylight, or access-control approach point.
This model is now a discontinued SECO-LARM product, so the main buyer concern is correct replacement planning. The E-9680-10B25 is different from the newer E-9630-4S328DA, E-9643-6S328DA, and E-9655-8S328DA long-range curtain sensors in range, voltage details, body size, beam count, and wiring approach. If a customer is replacing an installed unit, the original model label, body length, beam count, relay wiring, tamper circuit, and available power should be checked before purchasing a substitute.
Compatible With
- SECO-LARM E-9680-10B25 discontinued 10-beam IR curtain sensor
- Indoor/outdoor doorway, window, fence-top, skylight, and compact perimeter openings
- Access-control and alarm systems accepting dry-contact NO/NC relay output

Technician Note
Because this model is discontinued, treat any order as a replacement verification job. Match the installed unit by model label, beam count, body length, power, relay output, and mounting requirements before suggesting a newer curtain sensor.
Before Ordering
- Confirm whether the customer needs the exact discontinued E-9680-10B25 or a newer replacement option.
- Measure the installed sensor body and opening height.
- Check 12-24 VDC power availability and relay wiring.
- Confirm whether single-beam or two-adjacent-beam trigger logic is used.
- Check whether tamper wiring is connected to the access-control or alarm panel.
Professional Advisory
Photobeam and curtain sensors should be installed, aligned, and tested by a qualified gate, door, or access-control technician when used around moving gates, overhead doors, maglocks, or perimeter security circuits. Do not bypass monitored safety devices or rely on a non-monitored alarm beam as an entrapment protection device unless the operator manual specifically allows that setup.
Important Ordering Warnings
- This is a discontinued model. Confirm availability and replacement direction before upload.
- Do not treat newer 4, 6, or 8 beam curtain sensors as automatic exact replacements for a 10-beam E-9680-10B25 installation.
Product Questions
Is the E-9680-10B25 still a current SECO-LARM model?
No. It is listed as a discontinued 10-beam IR curtain sensor, so replacement planning should include careful comparison with current SECO-LARM curtain barrier models.
What is the range of the E-9680-10B25?
The older model is rated for 25 ft outdoors and 50 ft indoors.
Can a 4-beam, 6-beam, or 8-beam new model replace it?
Possibly in some applications, but not as an automatic one-for-one replacement. Beam count, height, wiring, range, and mounting must be checked.
What systems can use this sensor?
It is generally used with access-control or alarm systems that accept the sensor's dry-contact relay output and provide compatible low-voltage power.
Is this the right choice for gate entrapment protection?
Only use it for a gate safety input if the gate operator manual specifically supports this type of device and wiring method.
