c) remove and store ‘ENABLE’ key in a SAFE
and ACCESSIBLE place.
ALARM RAISED IN A FURTHER ZONE
When one or more additional fire detectors/callpoints
activates, the following occur:
a) The Red common ‘FIRE’ indicator remains
lit,
Note: A ‘FIRE ’ condition returning approximately
eight [8] seconds after pressing ‘RESET ’
indicates that a device is still in the ‘FIRE ’
mode.
b) the additional Red ZONE indicator[s] light,
c) the original ZONE indicator remains lit,
d) the Sounders will again sound [pulsing or
continuously, as programmed],
2.5
TEST PROCEDURES
3.1
LAMP TEST
e) the indicators [if installed] on the additional
activated devices light,
The indicators are all Light Emitting Diodes [LEDs]. To
check for failed LEDs:
f) any Alarm Auxiliaries associated with the
additional Zone[s] in ‘FIRE’ mode, will
operate.
a) Operate the ‘LAMP TEST’ switch, all LEDs
should light,
b) identify any failed LED.
SILENCE ALARM
CAUTION:
Refer to para 2.2.
2.6
3.
RESET
CAUTION:
BEFORE RESETTING THE CONTROLLER,
CHECK THAT THE SYSTEM HAS BEEN
SILENCED AND THAT ALL DEVICES
ACTIVATED DURING FIRE [E.G.
CALLPOINTS] HAVE BEEN RESET.
a) Operate the ‘RESET’ switch, the following
will occur,

DO NOT ATTEMPT TO RENEW ANY FAILED
LED. THEY SHOULD LAST THE LIFETIME
OF THE EQUIPMENT. CONTACT THORN
SECURITY LIMITED OR LOCAL
AUTHORISED DISTRIBUTOR FOR
SERVICE.

3.2
ZONE TEST
The object of this test is to check that the detectors/callpoints
installed in a Zone, can send a ‘FIRE’ signal which can be
correctly identified at the Controller.
Note: If a ‘FIRE’ condition occurs in a Zone NOT
under TEST, the Test indicates clear and
‘FIRE ’ indications will be given. The Zone
under Test will REMAIN isolated. Only when
the ‘FIRE’ condition has been CLEARED and
RESET can Zone Test continue.

The Controller will not permit transmission of spurious
‘FIRE’ signals from zones during periodic testing provided
the tests are carried out in accordance with instructions set in
para 3.
To check that a detector is capable of operating, simulate a
‘FIRE’ condition using the appropriate detector testing
method. Detectors should be tested on a rota basis and
servicing records kept.
‘One shot' detectors, such as fusible link heat detectors,
MUST NOT be tested. When testing a callpoint DO NOT
break the glass, open the front cover or use test key provided,
replace cover after test.
a) Operate the ‘ZONE TEST’ switch for the
appropriate Zone,
WARNING:
i) The appropriate numbered Zone ‘FAULT’
indicator will light and the Internal
Audible Warning will activate,
IF AN ION-CHAMBER SMOKE DETECTOR
IS FOUND TO HAVE BEEN REMOVED AND
CANNOT BE LOCATED, INFORM THORN
SECURITY LIMITED OR THEIR LOCAL
DISTRIBUTOR IMMEDIATELY.
b) activate a detector [using an approved test
method] or a callpoint [open front cover or
use key] installed in the Zone under test,
THESE DETECTORS CONTAIN RADIO
ACTIVE MATERIAL. IN THE U.K, REFER TO
THE RADIOACTIVE SUBSTANCES
IMPORTANT NOTICE SUPPLIED BY THORN
SECURITY LIMITED; REF TSG 10.4 AND
ALSO, IN THE CASE OF FACTORIES,
HMSO FORM F2479.
c) check that the Zone ‘FIRE’ indication is
given,
d) the Zone will automatically reset after
approximately 15 seconds. If smoke is still
present in the detector, the Zone will return
to a ‘FIRE’ situation and reset after a further
15 seconds,
e) repeat steps a) to d) for each Zone to be
tested.
When the Zone Test is complete, return the ‘ZONE TEST’
switch to the normal position. Ensure Zone ‘FAULT’ is
clear.

b) perform a Zone Test, as described in para
3.2. Note that ‘FIRE’ indicator on the
Controller does not light,
c) press the ‘LAMP TEST’ switch and check
all the indicators light.
System 1700 requires no maintenance to keep it in working
order. As LIFE and PROPERTY is being protected, it is
important that the system is tested at regular intervals.
Note: The Fire Department should be consulted for
guidance on any regulations which they
enforce with reference to frequency and
contents of any testing done on systems.
WEEKLY TESTS
a) Check that no FAULT indicators are lit,
PERIODIC TESTING AND
MAINTENANCE
Where the Controller uses a Remote Manned Centre
Signalling facility, tests must be carried at regular
intervals. The times of tests should be agreed with the
Centre manager or the Fire Department.
PERIODIC TESTS
4.1.2
MONTHLY TESTS
a) Perform the Weekly Tests as a preliminary to
the Monthly Tests,
b) if a ‘FIRE’ or ‘FAULT’ condition occurs
during the preliminary Weekly Tests, check
all Repeater Units fitted in the system
indicate correctly,
c) c h e c k a l l b a t t e r i e s i n s t a l l e d f o r
deterioration. NO battery maintenance is
needed. If there are obvious signs of

deterioration, a battery should be
replaced. The normal life of the batteries
used is four [4] years, after which they
should be replaced.

FAULT CONDITION
6.
FIRST-AID FAULT-FINDING
6.1
PRIMARY POWER SOURCE [LINE]
‘FAULT’ indicator ON, Internal Audible Warning operating,
‘POWER’ indicator OFF and ‘POWER’ LED [D8] on the
PSU OFF:
a) Check that the Line supply to Charger Unit
is present,
When a ‘FAULT’ appears in the system the following
occurs:
b) check that the voltage is within limits [±10%
of 110V or 240V],
a) The Amber common ‘FAULT’ indicator
lights, this indicator will be lit alone or in
combination with any of the following:
c) check security of connections to Charger
Unit,
i) The Green ‘POWER’ indicator lit;
ii) a Zone Fault indicator lit,
d) check any external Line Fuses,
e) check Controller Line fuse situated on the
side of the Charger Unit.
b) the Internal Audible Warning sounding,
c) the common Fault Auxiliaries functioning,
d) a ‘FAULT’ signal being transmitted to the
Remote Centre [if applicable],
6.2
BATTERY
‘FAULT’ indicator ON and ‘POWER ON’ indicator OFF,
Internal Audible Warning operating:
a) Check Controller battery fuse,
Note: When the presence of a fault is detected,
perform First-Aid Fault-Finding [para 6].
b) check security of connections to battery,
c) check surfaces of battery connections for
cleanliness.
Rectification of the ‘FAULT’ will cause:
e) the ‘FAULT’ indicator to go OFF,
f) the Controller Internal Audible Warning to
silence,
g) the Fault Auxiliaries to return to the
‘STANDBY’ mode,
h) the signalling output to restore to the
‘STANDBY’ mode. This will indicate to
the Remote Centre [if applicable] that the
system is again functioning correctly.
