Hold Open Mode
When the gates are in hold open mode, the obstacles are opened and remain open, so that
passage through the lane and take place freely, in both directions.
Hold open mode, can be triggered by either: -
1. A volt free normally open contact connected to the fire alarm input, or
2. A volt free normally open contact connected to any open command (i.e
. direction ‘A’ or ‘B’).
Note(s)
1. After 2 seconds the GREEN ARROW and RED CROSS stop working FLASHING.
Anyone using the gates MUST be trained in their correct use. Failure to
provide such training may result in serious accidents or injuries.
Make sure lane is clear of user before removing the hold open command.
If the open pulse is permanent and longer than the OPEN DELAY, the logic
assumes a HOLD OPEN status and the gates will remain open until the
open pulse is removed. Once the pulse is removed the gate will close
without any safety.
4.6
Power failure
On power failure the gate will remain in the position they were in when the power failed. The
gates are unlocked and can be manually pushed in any direction providing safe passage.
Make sure lane is clear of users before restoring the power.
If the open pulse is permanent and longer than the OPEN DELAY, the logic
assumes a HOLD OPEN status and the gates will remain open until the
open pulse is removed. Once the pulse is removed the gate will close
without any safety.
4.7
Fire alarm input
If a fire alarm interface is fitted the gates can be set to open in either direction depending on site
requirements.
4.8
Emergency evacuation
There are sometimes other emergencies apart from fire and power failure that require the gates
to be opened. In this situation via an optional desk top console an emergency push button,
reset via a key can be used to open all lanes.
Alternatively, a break-glass mounted close to the gates can be use.
