Introduction

The Precepten range of conventional control panels is a powerful yet user friendly series of control panels, approved by the Loss Prevention Certification Board, U.K. to EN54-2 and EN54-4.

The Precept range has earned a reputation over many years for quality and reliability and is recognised as a market leader in many countries around the world. This latest generation, Precepten, takes advantage of the very latest technological advancements both in terms of design and manufacturing techniques to meet the exacting requirements of the latest European standards.

Each panel in this series has extensive configuration options but is easy to install, programme and operate. This is supported by comprehensive documentation on commissioning, operation and maintenance. The panels are designed for use with a wide range of manufacturers' detectors. A complete range of fully flush and semi-flush bezels can be supplied for all Precepten control panels. There is also a comprehensive range of other compatible equipment such as repeaters, relays and power supply units, available to meet customer requirements.



Switching regulator power supplies with temperature compensated battery charging High efficiency voltage regulation. Battery charging voltage is automatically adjusted between 28.25 and 26.73 Vdc over an ambient temperature range of -10°C to + 50*#176;C.
Battery disconnect Protects the battery from permanent damage due to over discharge by automatically disconnecting it when the battery voltage falls to 19.5V
Class change input Operates all sounders for up to five seconds.
Configurable Detection Zones Simple and flexible display-based configuration process allowing detection zones to be configured for any of the following:
Latching or non-latching fire indication
Delayed or non-delayed output operation.MbrShort Circuit = Fault OR Short Circuit = Fire
Active fault monitoring on detection zones. (Non_intrinsically safe applications only). Factory configuration. Latching, non-delay, standard (non-OS), S/C = Fault.
Reduces zone monitoring current and therefore reduces the required battery capacity.
Maintains zone wiring continuity following the removal of a detector, while still providing a fault indication on the panel.
Selectable Zonal or General alarm sounder operation with sounders in alert or silent in adjacent zones. Selectable via DIL switches on the motherboard.
The standard sounders on the two and four zone panels can be used in General or Zonal modes. (These sounders always operate in General mode on 8, 16 and 32 zone panels regardless of DIL switch setting).
The output expansion system (later) provides additional sounder circuits for General or zonal use on the 8, 16 and 32 zone panels.
Conifurable Fire Routing, Fire Protection and Fault Routing output relays. Configuration links on the motherboard allow each output relay to be individually selected to the EN54 powered/fault monitored mode or non-EN54 comliant volt-free changeover contacts.
Factory configuration: Fully Monitored (EN54 Mode).
Reset Relay A volt-free changover contact operating for ten seconds on panel fire alarm reset.
Auxiliary 24Vdc power supply output Protected by an electronic fuse. Operation of the fuse is indicated on the display. The fuse is reset by pressing the Reset button on the display.
Open Collector Ouputs Evacuate active.
Buzzer Active
Disablement Active
Zonal fire for each zone up to zone 4 (Zonal output expansion on 8-32 zone versions via output boards later).
Remote Inputs Remote Evacuate
Remote Silence Alarms
Remote Reset
Earth Fault Monitoring Can be disabled via link on the motherboard.
Zone/Ouput disablement feature The following circuits can be independently/disabled/enabled:
 Each Zone
 Fire Routing
 Fire Protection
 Fault Routing
 All Sounders
One Man Zone Test Each zone can be independently set to the One Man test condition. Sounders can be configured to either operate briefly to confirm the panel has detected the test fire, or no sounder operation during the test fire.
One Man Sounder Test Operates the sounder intermittently
Configurable Delay Mode Facility Flexible system allows:
 Any zone to be configured as a delay zone.
 Single-stage or two-stage delay.
 Selectable 1 to 10 minute delay period (for single stage and two stage delay modes)
 Selection of the outputs to be delayed (fire routing and/or Fire Protection and/or Sounders) - can be any combination.
Other configurable features
  • Prevent the Fire Protection output operating from a fire condition on a "Non-Latch" zone.
  • Inhibit the silencing and resetting panel of the panel for 3 minutes following occurrence of a fire alarm.
  • Set the sounders to operater only when the panel is in the evacuate condition.
  • Inhibit the resetting of the fire alarm condition until the alarm sounders have been silenced.
  • Disable the internal panel buzzer
  • Select the latching fault mode where all fault conditions latch until the panel is manually reset
  • Restore factory default configuration of zones and outputs to be delayed
Repeater panels Support for up to five repeater panels via two-wire RS485 serial communication.
