The Fire-Cryer® Plus Multi Message Switching PCB
Part Ref: MMSP
Features:
¾2 Sounder Circuits rated @ 2A per circuit
¾7 messages
¾Fully monitored sounder circuits with two additional fully monitored inputs for panic or incident alarm
¾All messages synchronised within a 4 zone (8 Sounder Circuits) system (when used with the Vimpex Zone
Extension PCB Part Ref. ZEP)
¾Fully expandable with limitless zones with added MMSP and ZEP
¾Diagnostic LEDs
¾Optional integrated keypad and enable key switch for message selection
¾Optional Metal enclosure designed around the Kentec range of panels. Can be delivered prewired with or
without a PSU
LED Indicators (Refer to Figure 3)
Power healthy and MMSP powered illuminates the GREEN LED cunder ‘Reset’.
Processor healthy will be indicated by a ‘blinking’ GREEN LED dmarked ‘PROC’
Transmission of a message illuminates the RED LEDs efon both sounder circuits (S1A and S1B)
Activation of auxiliary messages (MA through to MF) will illuminate the corresponding RED LEDs g, h, i, j, k
If the input to S1A or S1B is energised and LED eor fis not illuminated, then the fuses should be checked. If LED
eor fis illuminated and the incorrect message is being broadcast this may indicate excessive volt drop (<20VDC)
Terminals (Refer to Figure 3)
AUX - - + + 24VDC Input
S1A / S1B AUX EOL. The sounder circuits S1A and S1B are provided with auxiliary EOL terminals. Fit the panel
manufacturer’s recommended EOL Resistor here. This suppresses fault signals when an auxiliary message is
broadcast.
MA, MB, MC, MD, ME and MF These are 6 additional inputs. MA and MB are fully monitored inputs requiring a 3K3Ω
EOL termination resistor which is supplied. To activate MA or MB, a 470Ωresistor is needed in series with the switch.
The remaining four inputs when linked to COM will trigger the remaining auxiliary messages.
INTERBOARD SYNC This terminal is used to link multiple MMSPs and ensures synchronisation for S1A and S1B
across all MMSPs
Factory Set Options. The following options can be requested when placing the order
Pulsing Input – If the sounder inputs are pulsed 1 second on, 1 second off, this will automatically broadcast a pre
selected message, usually an ALERT or pre-alarm message. FACTORY DEFAULT IS OFF
Auto All Clear Mode – If the ALERT or pre-alarm message is cancelled a pre selected ALL CLEAR message will be
automatically broadcast. The number of repeats of the ALL CLEAR is also set at this time. FACTORY DEFAULT IS OFF
Timeout – This allows a message to be broadcast for a time set by DIL switches 1-4 (see Table 1) to allow for
investigation prior to evacuation. FACTORY DEFAULT IS OFF
Latch Inputs – Any or all inputs MA, MB, MC, MD, ME and MF can be latched. FACTORY DEFAULT IS OFF
Message Termination - Messages can be set to terminate immediately or at end of message. FACTORY DEFAULT IS
END OF MESSAGE
User Options
8-way DIL switch
SW7 and SW8 are used to disable MA and/or MB indicators respectively on the keypad.
SW1-4 are used to set the time in ‘timeout mode’ as a field adjustable function. (See Table 1)
SW5 and SW6 have no function at present.
