Electric Door Release
Fail-Secure releases are the most commonly used devices, they require power to
release the lock and will secure the door upon power failure. Fail-Safe lock releases
and magnetic locks require continuous power to hold the lock and will release the door
upon power failure. All of these types can be accommodated providing they are rated
at 12V DC with a maximum current consumption of 0.5A. For lock releases that have
different requirements contact your distributor for further guidance.
Trades Button (optional)
The entrance panels may be ordered with an optional Trades button to allow free
access during certain hours (used in conjunction with a time clock). Momentarily
pressing the button will operate the lock release for a fixed period (adjustable, typically
5 seconds).
Exit Button (optional)
Typically this facility is used to allow personnel to freely exit through the controlled
entrance. Momentarily operating the push-button will directly operate the lock release
for a fixed period (adjustable, typically 5 seconds).
Fire Switch (optional)
The fire switch is usually a key or lever switch which can be operated by the fire-brigade
to gain access to the building. To use this feature the Lock release(s) must be
continuously rated.
Door Monitor Switch (optional)
Each Telephone has a green LED indicator above the DOOR button to show when the
door is open. This is detected by the closure of a door monitor switch. The switch
should be rated at 1A ( for up to 60 phones). Lock Releases are available with an
integral Door Monitoring switch.
