Vimpex FC3/MMSP Fire-Cryer Plus Multi-Message Switching PCB
To use the Fire-Cryer Plus sounders in their multi-message mode it is necessary to send commands to the sounders to instruct them which of the seven messages they should broadcast. This is achieved by introducing the Multi-Message Switching PCB (MMSP). The MMSP has developed into a versatile, expandable and user-friendly interface to control up to seven different messages using just two cores.
It is capable of handling ‘One out all out’ scenarios as well as phased evacuation or staged fire alarms. It is as ideally suited to new compact conventional single zone builds, complex networked sites with many zones as well as retrofitting to existing systems. With the addition of interfaces such as the Hochiki CHQ-DSC and the Apollo SCC the Fire-Cryer Plus can be successfully installed on addressable loops. Each MMSP has two 2 amp sounder circuits which are monitored by the Fire Alarm Control Panel.
The MMSP can be supplied separately or within enclosures housing the MMSP with or without a Keypad, Zone Extension PCB (ZEP) and PSUs – see Voice Message Controllers opposite. The primary message is usually ‘FIRE’ or ‘EVACUATE’ and is preceded by an alerting tone chosen by the user. The remaining six messages are known as auxiliary messages as any of these will be overridden by the primary message.
The MMSP has a number of inputs for switching the auxiliary messages, either from the keypad (if fitted) or external inputs, such as a relay, key-switch, IO unit, call point or similar. Two of the six auxiliary inputs can be configured as monitored inputs; providing the opportunity to include panic alarms and terrorist or bomb alerts. The MMSP is installed between the field sounder circuits and either directly to the Fire Alarm Control Panel (FACP) or via a loop interface.
