Introduction
The information provided in this manual covers the Saffire range of fire
alarm control panels. The Saffire range is designed to meet the
requirements of BS5839 Parts 1 & 4 1988 and includes panels of 1 and
2 zones.
This product should be installed, commissioned and maintained by
suitably qualified service personnel with reference to IEE regulations
and any statutory requirements.
General Description
The Saffire is a microprocessor controlled fire alarm control panel. It is
provided with one or two sense zones (detector zones) to connect to fire
detection devices, two alarm zones (bell zones) to connect to audio/
visual devices and a set of volt free changeover contacts which operate
on fire. If a fire is detected by a device on a sense zone, the alarm
zone devices will operate automatically and the zone that detected the
fire will be indicated on the front panel. The panel also allows the user
to operate the alarms manually.
Installation Procedure
Before proceeding with the installation, please read the section Panel
Operation - You will need to know the access code during installation.
Installation of the panel should be carried out by qualified
personnel.
Using the metal box as a template, mark the position of the fixing holes
on the wall. Drill and plug the wall then screw the panel to the wall.
Ensure the panel is free from knockout discs, swarf and other debris.
Do not connect any cables until after the following test is performed.
All end of line resistors should be fitted in the panel at this stage.
Connect the panel mains input to an exclusive 240V AC fused supply.
Switch the mains supply on. The internal buzzer will sound. Connect
two sealed lead acid batteries to the panel. They should be connected
in series, providing a 24V DC supply. With both the mains and battery
supplies connected, the panel should be silent and in its normal
operating mode (power lamp on, alarms & buzzer silent).

Saffire Instruction Manual 3
If a fault is indicated, refer to the fault finding section before
proceeding. Disconnect the batteries and switch off the mains supply.
Remove the 3k3 end of line resistor from sense zone 1. Terminate
sense zone 1 circuit wiring in the panel observing correct polarity and fit
the end of line resistor at the extreme end of the circuit. Check that all
the detectors and call points are correctly wired. With sense zone 1
connected and all other end of line resistors fitted inside the panel,
connect the mains and battery supplies. If the panel indicates a fault,
refer to the fault finding section before proceeding. Do not megger
cables connected to either the panel or any field devices. If no faults
are indicated then power down the panel and follow the same procedure
with the additional sense zones and then the alarm zones. Adding the
zones one at a time makes fault finding and commissioning much
simpler. Make sure that no bare wires come into contact with the panel
circuit boards during installation.
Detector Head Removal
The Saffire range of panels support head removal. The basic principle
of head removal is to ensure that all call points will function even if a
detector head has been removed. When a detector head is removed,
the panel will show a fault but the sense zone circuit will remain intact.
Head removal requires either zener clamp bases or schottky diode
bases with the appropriate end of line device to be fitted. Consult the
table on page 7 for more information.

Panel Operation
Entering the access code.
Before being able to access the Reset, Silence and Evacuate functions,
the panel access code must first be entered. To activate the keypad,
press the front panel buttons in the following sequence: 1-3-1-2
The panel should bleep after each button press. The Enabled lamp
flashing indicates that the keypad is now active. If no button is pressed
for approximately 2 minutes the keypad will deactivate.
Performing a lamp test.
If the panel is in its normal condition, pressing the Reset button will
cause the panel to perform a lamp test. This will also deactivate the
keypad.
Resetting the panel after a fire is detected.
To reset the panel after a fire condition, press the Silence button
followed by the Reset button.
Resetting the panel.
If any of the panel functions have been activated, pressing the Reset
button will return the panel to its normal condition.
Silencing the alarms.
If a fire is detected, the panel will automatically activate the alarm
circuits. To silence the alarms, press the Silence button. The internal
buzzer will continue to sound until the Reset button is pressed.
Silencing the internal buzzer.
If a fault is detected by the panel, the internal buzzer will sound. To
silence the buzzer press the Silence button. The buzzer will continue to
bleep every 25 seconds. A CPU Fault cannot be silenced.
Manually sounding the alarms.
Pressing the Evacuate button will sound the alarms. To silence the
alarms after the Evacuate button has been pressed, press the Reset
button.

Fault Finding
Reset, Silence & Evacuate buttons not working.
Enter access code to enable keypad. Press the buttons in the following
sequence: 1-3-1-2. The panel should bleep after each button press.
Fault lamp & zone fault lamp flashing, internal buzzer sounding.
Faults monitored are:
• Open circuits on the sense zone wiring.
• Short circuits on the sense zone wiring.
• Detector head removal
Check all detectors and call points on the sense zone indicated. Check
wiring is as in example diagrams and ensure the end of line monitor is
a 3k3 resistor or an active end of line device.
Fault lamp lit and internal buzzer sounding.
Faults monitored are:
• Open circuits on the alarm zone wiring.
• Short circuits on the alarm zone wiring.
• Blown alarm fuses.
• Blown battery fuse or battery supply missing.
• Blown mains fuse or mains supply missing.
• CPU fault.
Check all fuses. If blown replace only with identical parts. Check
alarm zone wiring is as in example diagrams and ensure the end of line
monitor is a 10k resistor. Check incoming mains supply and condition
of batteries. If no problems are found then reset the processor. Inside
the panel on the main circuit board are two push buttons marked CPU
RESET and W/D RESET. Press CPU RESET followed by W/D
RESET.
Panel does not indicate fire when a call point or detector is tested.
Either a faulty call point/detector or wiring not as shown in diagrams.
Check the firing resistance of the device is 510 ± 200 ohms and ensure
end of line monitor is a 3k3 resistor or active end of line device.
Head removal not working.
Check compatible base is being used and is wired correctly. Either a
zener clamp base with a 3k3 end of line resistor or a schottky diode
base with an active end of line device must be used.

Sense Zone Wiring Diagrams
Find the detector bases you will be using in the table on page 7 and
check to see which end of line device is required - either a 3k3 resistor
or an active end of line unit. The 3k3 resistor should be used if a zone
is comprised entirely of call points.

The 100uF capacitor should be fitted at the sense zone terminals inside
the fire alarm panel. The Saffire panel is supplied with 3k3 sense zone
end of line resistors. Active end of line units are supplied separately.
Remote indicator connection details are shown in the table on page 7.
