4.4 MAXIMUM LOOP CABLE LENGTH RECOMMENDATIONS
With an addressable system, some care must be taken when calculating the appropriate cable gauge for the system. The main
limitation is that during an alarm condition (maximum current draw), the voltage at all detectors must be at least 17 Volts with at
least 5V of superimposed data signal.
The exact calculation equations are beyond the scope of this manual, because of the distributed load of the sounders on the loop,
but the following table gives a rough guide for maximum cable lengths at various current loads for 3 different cable gauges.
MAXIMUM LOOP CURRENT (IN ALARM)
500 mA
400 mA
300 mA
200 mA
1mm CSA cable
500 m
625 m
830 m
1250 m
1.5mm CSA cable
750 m
930 m
1250 m
1870 m
2.5mm CSA cable
1000 m
1250 m
1660 m
2500 m
E.g. A system with a maximum load of 300mA using 1.5mm cable can have a maximum loop run of 1250 m end to end. When
Installed the cable characteristics should meet the following parameters:-
+ve in to +ve out less than 22 ohms.
-ve in to -ve out less than 22 ohms (may need to temporarily disable isolators to measure).
+ve to –ve greater than 500k ohm.
+ve to Earth greater than 1M ohm.
-ve to Earth greater than 1M ohm.
+ve to –ve less than 50 mV pickup (on AC & DC scales).
+ve to –ve Capacitance Less than 0.5uF.
+ve to Earth Capacitance Less than 0.5uF.
-ve to Earth Capacitance Less than 0.5uF
Maximum loop load 500mA
4.5 BATTERY CALCULATIONS
All systems will have a required stand by time and alarm time. The usual Standby times are 24 hours, 48 hours, or 72 hours,
depending on the type of system. Generally 30 minutes of alarm time is considered sufficient.
Information on calculating the required battery size can be found later in this manual. Alternatively, a battery calculation
spreadsheet is available. Please contact your distributor for details.
4.6 CHOOSING AUDIBLE & VISUAL WARNING DEVICES
There are a number of options for Audible & visual Devices that can be directly or indirectly connected to one of the 4 loops on
Premier Quatro:
A maximum of 64 loop powered sounders are permitted on each loop (which can be either stand-alone sounders or sounders in the
bases of detectors. A MAXIMUM OF 250 DEVICES CAN BE CONNECTED TO EACH LOOP, WITH ADDRESSES 1 TO 250 WHICH CAN
OCCUR IN ANY ORDER. Short circuit isolators should be used to prevent losing the whole loop in the event of a single short circuit
fault. They should be fitted to each zone boundary, such that any short circuit will only affect the devices in 1 zone.
4.6.1 ADDRESSABLE STAND-ALONE SOUNDERS
This type of sounder takes one of the 250 addresses available on each loop. The address is selected via DIP switches 1 to 8. It can be
activated individually, or in groups related to its zone number, loop number or panel number (as determined by the cause and
effect programmed). An example of this type of sounder is the Zeta Maxitone Addressable Sounder
4.6.2 SOUNDER BASE (Sandwich Sounder – Remote LED Mode)
The sandwich sounder is a type of Platform sounder that fits between a MKII detector and a MKII base. It is controlled via the
detector`s remote LED pin. As it is a platform sounder the control panel can`t “see” it. It is monitored via the loop cable, in a similar
way to a conventional sounder
4.6.3 SOUNDER BASE (Sandwich Sounder – Addressed Mode)
The sandwich sounder can also be given an address via the Hand Held Address Programmer
(see section 6.4.1)
. When Addressed
the sandwich sounder will behave in a similar way as a standalone sounder.
4.6.4 ADDRESSABLE SOUNDER CIRCUIT CONTROLLER
The Zeta addressable sounder circuit controllers (ZASC-MI) can be used to connect one conventional sounder circuit to one address
on the loop. It needs external power to be supplied from a suitable 24 V power supply.
