Health and Safety
Any installation must comply with any local Fire or Health and Safety regulations. Any
secured door that may be part of an escape route should be fitted with:
•
A Fail-Safe lock to ensure that the door is released if the power fails. KMS
recommend that a magnetic lock is used as these are less likely to jam or seize.
•
A normally closed Break-Glass or manual break in the lock supply wiring to
ensure that the Fail-Safe lock can be immediately de-powered.
•
Note:
All inputs are 0v triggered, i.e. wire between RTE and
0v to trigger system. Do not use building ground!
Door Contacts
Door contact inputs are switched off by default. These can be switched on by KMS
with the appropriate open warning time set. This input is set as normally closed
meaning that when the door is closed the contact between DR1/2 and 0v must be
closed circuit. This can be inverted to suit installation.
