1. SAFETY
This Fire Alarm Panel is safe to operate provided it has been installed in compliance with the Manufacturers
instructions and used in accordance with the Manual.
Do not open the Fire Alarm Panel enclosure . There is no need to open the enclosure except to carry out
commissioning, maintenance and remedial work. This work must only be carried out by competent service
personnel who are fully conversant with the contents of the separate engineering manual for this product.
If the enclosure is damaged in any way, expert advice should be sought regarding its repair.
Regular Servicing of the Fire Alarm System is highly recommended, preferably on a continuous maintenance
contract and by a competent organisation. A fully-itemised report of the installation should be obtained at least
annually.

2. FIRE ALARM SYSTEMS – AN OVERVIEW
The primary purpose of a Fire Alarm System is to provide an early warning of a fire so that people and animals
can be evacuated and action taken to stop the fire as soon as possible – all according to a predetermined plan.
Alarms may be raised automatically by Smoke or Heat Detectors, or manually be a person operating a Manual
Call Point.
To ensure an Alarm is dealt with in an orderly manner, it is important to know where the alarm is coming from.
To do this, Fire Alarm systems are usually split into Zones, each covering a different area of a building.
When an Alarm has been raised, the Fire Alarm Panel responds by indicating the Zone in which the Alarm has
occurred and activating all relevant Sounders, Bells and other Alarm Outputs to provide a warning of the fire.
•
A Remote Output: normally used to transmit an Alarm condition to an off-site permanently manned
monitoring centre. On receipt of the Alarm signal, the Centre notifies the local Fire Brigade of the Fire
Condition.
•
An Auxiliary Output: normally used to trigger local fire fighting equipment such as magnetic door
release systems (to automatically close fire doors), plant shutdown systems (to automatically switch off
potentially hazardous machines), sprinkler systems, etc.
Fault Monitoring
For obvious reasons the reliability of the Fire Alarm System is paramount. To this end, the fire alarm panel
continuously monitors all connections between Detectors, Manual Call Points and Sounders and checks its own
power supply and back-up batteries for faults.
If a fault is detected anywhere on the System, the Panel responds by illuminating one or more of the fault
light(s) located on the front of its enclosure and by sounding its internal fault buzzer. The Panel’s Fault Output
is also activates, sending notification of the fault (if connected) to a remote manned monitoring centre or other
electronic equipment, as required.
Delays
A Fire Alarm System can be prone to conditions that lead to frequent and unavoidable false alarms, a common
example being a waiting room filled with cigarette smoke. In areas such as these, it is acceptable to apply a
Delay to the Panel, which postpones the activation of the Alarm Sounders for a predetermined time. This Delay
period gives a responsible person time to investigate the cause of the Alarm and override the Delay if the cause
is found to be a true fire hazard to reset the Panel if the cause is found to be a False Alarm.
Disablements
In abnormal conditions, certain parts of the Fire Alarm System can be temporarily turned off (disabled) to suit
prevailing conditions. For example, if there is a risk of a false alarm occurring in a zone from vehicle exhaust
smoke in a loading bay, it is possible to disable that Zone during the risk period, then enable it again
afterwards. Another example of the disablement of outputs is during a routine test, or temporary fault.
Power Supply Equipment- General Description.
The NPSX FACP has an integral linear power supply capable of supplying 1.2 amps in total. It contains a current
limited output for charging sealed lead acid batteries (7 Ah maximum). The PSE is monitored for main supply
failure, the battery not taking a charge and low battery voltage. If the battery voltage drops below approximately
20VDC (a fault condition), the battery charging current will be turned off , thus stopping charging. This PSE is
only capable of supplying power to the CIE, and is not designed for any other use.
