Key Release
Emergency Vehicle Access Conditions
Fail-Secure Manual Release System (Owner Installed)
Solenoid lock does NOT allow the clutch plate to rotate when:
• The AC power is on but the operator is not cycling.
• The AC power is turned off.
• AC power failure.
1. During normal AC powered operation: emergency vehicles access the gate by a separate emergency access device individually installed
and wired to your gate system. The type of devices that can be used in your community depends on your city codes. These devices may
include (but are not limited to) Fire Department lock boxes, Click-2-Enter radio receivers, strobe light sensors, siren sensors, etc.
2. In the event of an AC power failure: the emergency vehicle access device will not function because the gate operator is un-powered.
“Fail-Safe” or “Fail-Secure” release systems for the 9150 allow the gate to be manually operated during an AC power failure.
ONLY the “Fail-Safe” release system allows the gate to be manually operated without unlocking the operator first and has been designed
that way to allow emergency personnel to immediately manually operate the gate from either side under emergency situations. See this
page and previous page for more information.
This automatic vehicular gate system is designed to allow access to emergency vehicles under different operating conditions.

This manual release system (Installed 2600-865 Fail-Secure Manual Release Kit) allows the gate to be manually
operated ONLY after unlocking the gate operator. Power outages or turning power off WILL NOT allow gate to be
manually operated without physically unlocking the gate operator with the key first. This option is typically used in Class
III and Class IV applications. The gate operator “Fails” (Loss of AC power) in a “Secure” (Manually in-operable) condition.
SW 2, switch 4 must be ON.
Important: solenoid lock
MUST be in position shown.
