1. System Overview
The Clymac ZP system is a microprocessor based fire detection and alarm system. The control
panel accepts signals from call points, smoke sensors, heat sensors and interface units. It also
has outputs for audible and visual alarm devices together with auxiliary outputs for plant
shutdown control.
1.1 Addressable devices
Smoke detectors, heat detectors, call points and interface units are all “addressable” devices.
This means that the control panel is able to individually identify a fire or fault alarm from each
device. Each device is therefore allocated a number or “address” when the system is
commissioned. Each address is then programmed with a forty character text label, which will in
turn be displayed on the control panel’s text display in the event of an alarm.
An addressable system therefore enables the exact source of the incident to be identified quickly
reducing the search time and improving the chances of containing the incident.
1.2 Analogue detection
The ZP system utilizes analogue detection techniques to detect fire and fault incidents. An
analogue system is a very accurate method of detection and monitors the rate at which the
activity within a detector's sensing chamber changes. An analogue detection system therefore
reduces the occurrence of false alarms and increases detection performance of a real fire. It will
also identify faulty and dirty detectors thus reducing the cost of maintenance activities.
1.3 Controls and indications
All of the fire and fault occurrences are displayed on the control panel’s liquid crystal display
together with the text label when relevant
The alpha-numeric keypad is used for re-engineering the system if the building changes and for
other activities as printing out the systems archive log.
1.4 Continuous monitoring
The ZP system provides the user with total peace of mind. All of the control panel functions
and system devices are continuously monitored for their correct operation.
The cable used to interconnect all of the detectors, call points, interface units and sounders is
also continuously monitored for failure.
