(8)
Re-arm: This may be set to Auto or to Manual. Auto Re-arm means that at the end of
the Bell Duration period the circuit will repeat the alarm, if the alarm condition is still
present, or if it re-occurs. Manual re-arming will inhibit the circuit, once it has
generated an alarm, until the panel is reset.
(9)
Reset: If an alarm occurs the system alarm condition may be reset by the User, or by
the Engineer, or remotely via a telephone line and the DC3M. If an Engineer Reset is
required and the Engineer is not immediately available then the User may utilise the
Reset by Remote facility to phone for a special code number which will reset the
system (para 5.25);
(10)
Codes: The passcodes may be set to require four or six digits. If set to six digits and
only four have been allocated then the last two digits are assumed to be zeros.

Omitting Circuits
2.10.1
Circuits may be omitted so that they have no effect when activated, unless a tamper is
detected, and this requires two actions:
(1)
The circuit to be omitted must have the Attribute Omit (para 2.5.1) which is allocated
by the Engineer when commissioning the system;
(2)
The Omit/Enable circuits menu (7) must be used to Arm or Enable the circuit and this
may be done by suitable Users.
2.10.2
Assuming that the Engineer has previously allocated the Omit Attribute to selected circuits
then there two ways of activating the Omitted state:
(1)
Directly access the Omit/Enable Circuits menu (7) and use it to select the required
omitted circuits. This condition will be indicated by 'Circuits Omitted' being displayed
at the REM when the system is unset;
(2)
During the setting sequence the User may go to the Omit/Enable Circuits option and
select circuits with Attribute Omit which are to be omitted.
The circuits that have been selected to be omitted will be re-instated when the system is
unset and circuits omitted when the system is unset will be re-instated when the system is
set.
2.11
PSU Monitoring
2.11.1
The main CP internal PSU is continuously monitored for loss of power and this facility may
also be extended to remote PSUs, if fitted, by using circuits to monitor the PSU and an output
to control the monitoring. A loss of power will be indicated at the REM as AC Fail or Batt fault
and will also be logged.
2.11.2
The PSU battery or batteries are tested by isolating power for about a minute every hour and
measuring the battery voltage whilst it is on load. If the voltage is below a certain value then
an alarm is indicated.
2.11.3
Remote PSU will require up to three circuits to be designated as PSU monitor lines (para 2.4)
and to be connected to the PSU monitor connections. An output (para 2.6.3) designated PSU
Test will also be required and connected to the PSU to initiate the test.
2.11.4
The PSU monitoring facility is inhibited during a timed test (para 2.12) to allow new batteries
to be charged wihout generating an fault.
2.12
Other Facilities
2.12.1
Time Switch: May be used to provide a pre-selected timed output with two On times and two
Off times and each may be allocated to operate on any number of days of the week.
2.12.2
Time Lock: May be used to restrict Setting and Unsetting the System or Ward 1 to certain
times.
2.12.3
Event Log: An electronic log which will retain up to 285 events and which can be viewed or
printed.
2.12.4
Walk Test: Allows the system and or individual wards to be tested by recording circuit
activation without annunciating the alarms.
2.12.5
Circuit Text: Each circuit may be allocated a line of text, pre-selected from a dictionary of
about 500 words or characters, so that the alarms will be indicated by the circuit name
instead of the circuit type.
