23.12.2 Access PINs
For Grade 2 systems:
After 10 unsuccessful attempts with the incorrect PIN, the keypad or browser
will be disabled for 90 s; after a further 10 attempts with the incorrect PIN, the keypad or browser will be
disabled for a further 90 s. Once a correct PIN has been entered, it will reset the counter back to zero
allowing for a further 10 attempts before disablement.
For Grade 3 systems:
After 10 unsuccessful attempts with the incorrect PIN, the keypad or browser
will be disabled for 90 s; after each further attempt with an incorrect PIN the keypad or browser will be
disabled for a further 90 s. Once a correct PIN has been entered it will reset the counter back to zero
allowing for a further 10 attempts before disablement.
23.12.3 Engineer Access
An Engineer can only access the system if permitted by a ‘Manager’ user type (see ‘Engineer’ attribute
in
on page 200) and only for a specified time duration (see ‘Engineer Access’ in
page 261).
23.12.4 Keypad User Logoff
If no keys are pressed on a keypad for a specific duration (see ‘Keypad Timeout’ in
page 261), the user is automatically logged off.
23.13 Wiring of mains cable to the controller
Requirements:
A readily accessible approved disconnect device must be incorporated in the building installation
wiring. This must disconnect both phases at the same time. Acceptable devices are switches, circuit
breakers, or similar devices
l
The disconnect device must have at least 3mm distance between the contacts
l
Minimum size conductor used for connecting mains is 1.5mm square
l
The circuit breakers must have a maximum rating of 16A
The mains cable is secured to the metal V shaped bend in the base plate via a tie wrap such that the
metal bend is between the cable and the tie wrap. Ensure that the tie wrap is applied to the
supplementary insulation of the mains cable, that is, the outer PVC cable sleeve. The tie wrap must be
pulled extremely tightly such that when the cable is tugged there is no movement in the cable relative to
the tie wrap.
The Protective Earthing conductor should be fitted to the terminal block in such a way that if the mains
cable should slip in its anchorage, placing a strain on the conductors, the Protective Earthing conductor
will be the last item to take the strain.
The mains cable must be an approved type and marked HO5 VV-F or HO5 VVH2-F2.
The plastic tie wrap must be flammability rated V-1.
23.14 Maintenance controller
The system should be serviced in accordance with the service schedule that is in place. The only
replaceable parts on the controller are the mains fuse, standby battery and the time and date battery
(PCB mounted).
It is recommended that during a service the following be checked:
l
The Event Log to check if any standby battery tests have failed since last service – if standby
battery tests have failed then the standby battery should be checked.
l
The standby battery should be replaced as per the servicing schedule to ensure that it has
