Self-resetting emergency exit system
The systems main purpose is to ensure that whilst managing building egress, building security is maintained.
Secured by Design states that break glass emergency door exit release devices (often green in colour) on communal external doors that provide an important aid to egress in the event of an emergency have proven to be abused rendering some buildings insecure for long periods of time. SBD recommends vandal resistant stainless steel self-resetting emergency exit systems are installed as an alternative. The installation and system type must be in full compliance with the Building Regulations and achieve final ‘sign-off’ by local Building Control or Approved Inspector.
In these instances, the Urmet ref. RTE-EES shall be installed to meet the above Secure by design requirement.
The devices shall be suitable for use with fail safe releases and maglocks. Not fail secure (fail locked) releases.
The PRESS TO EXIT button shall use a normally open contact to trigger the access control or door entry system timing circuit, and also a normally closed contact which is connected in series with the cable supplying the release, meaning that if the access control or door entry system is offline, the power to the release will be mechanically cut and the door can always be opened.
The emergency illuminated PRESS TO ESCAPE button shall trigger the timing circuit within the device which in turn breaks the power to the release. After a pre-set period (1, 6, 12 or 24 minutes) the door will automatically re-lock.
The PRESS TO ESCAPE button shall also mechanically break the power to the release making the device truly fail safe.
The self-resetting emergency exit system shall also have additional inputs for events such as door open or threshold reporting.
