[1] An active manual release station disables automatic
operation and the abort function and simultaneously
activates the:
• Manual delay timer
• Prerelease circuit
• Prerelease strobe circuit (steady On)
• Prerelease horn circuit (60 pulses per minute)
[2] 10 seconds before the expiration of the manual delay
timer, the pre-release horn changes from 60 pulses
per minute to steady On.
[3] The manual delay timer expires and the release circuits activate.
[4] A manual reset at the fire alarm control panel deactivates the release
solenoids and the Releasing Module returns to the normal state.
