MZX-c+ Conventional Control Panels

The ZETTLER® MZX-c+ range of conventional fire detection control panels are designed to be both installer and user friendly. A high degree of flexibility and programmability allows the systems to be customised for a wide range of applications, without the need for any configuration software.

The range consists of 4, 8, 16 and 32 zone panels together with repeaters and a number of ancillary expansion modules. The 4, 8 and 16 zone models share the same housing whilst the 32 zone panel features a larger enclosure. Matching repeater panels all have built in 240Vac power supplies with the 8 zone repeater designed for use with both the 4 and 8 zone panels.

All the units are designed and manufactured to the highest standard and the range is approved by the Loss Prevention Certification Board (LPCB) to EN54 parts 2 and 4.

  • Configurable monitored or volt free outputs for Fire, Fault and Protection
  • Outputs for zones 1 to 4 (open collector) with 8, 16 or 32 zonal outputs provided by optional expansion boards
  • Outputs for Disablement active, Evacuate active and buzzer active (open collector)
  • Volt free reset relay. Active for 10 seconds following a panel reset
  • 8 to 32 zone systems can drive up to 12 expansion input / output modules per panel
  • Drive up to 5 repeater panels

Ancillaries and Expansion
A number of interface and expansion modules are available to provide the necessary ports and input / output capability required for more demanding and complex conventional schemes.

C1631 Repeater Interface Board provides an RS485 port for driving up to 5 repeater panels. One C1631 Repeater interface board is required for the panel and one for each repeater. Repeaters are supplied with a C1631 fitted.

C1630 Output Expansion Interface Board provides an RS485 port for driving up to 12 output expansion boards.

EXP 4 and EXP 4 PSU Expansion Housing are designed to house any combination of up to four output expansion boards. The PSU version is equipped with a 5A 24Vdc power supply and space for 2 x 12V 12Ah batteries.

EXP 5 and EXP 5 PSU Expansion Housing are similar to EXP 4 and EXP 4 PSU but accommodate five output expansion boards.

C1633 LED Driver Board provides eight open collector outputs rated @ 60mA. Outputs can be zonal alarm or common alarm.

C1634 Relay Output Module provides eight volt free changeover contacts rated at 1A 30Vdc. Outputs can be zonal alarm or common alarm.

C1635 Monitored Output Board provides eight fault monitored 24Vdc outputs. Power can be derived from the control panel or an external source. Outputs can be zonal alarm or common alarm.

C1651 MZXC+ Timer Module is an optional plug-in board with an alphanumeric LCD to provide a real-time clock display. The clock can be programmed to provide investigate delays and day night settings. The unit is also used to store and display a total count of the number of times the panel enters the alarm condition. This unit can be fitted to 8, 16 and 32 zone panels.


The user interface buttons and indicators are labelled using double sided printed inserts that allow the panel and repeater to be used in multiple markets with English and Arabic shipped as standard.
