16.1 16 channel I/O board
The 16 channel I/O boards can be individually configured using the Loop Explorer configuration programme and each channel can be
an input or an output.
When added to a control panel, all channels default to inputs with and their action when activated will be FAULT. Any or all channels
may be changed to outputs via the Loop Explorer configuration programme. When channels are changed to outputs they will default
to DEFAULT RING MODE. This means that they will switch on when a fire condition is present on the control panel as COMMON
ALARM, ZONED ALARM or 2-STAGE ALARM (see section 19.3.2).
Inputs to these boards are via opto-isolators, which offer good protection against noise and transient voltages. Channels configured
as outputs have an open collector transistor, so must be used with care to avoid damage by shorting or sourcing too much current.
For full details of 16 channel I/O boards refer to manual MAN-1056.
16.2 8 way relay board
The 8 way relay boards have individual, volt free changeover relay contacts which can be configured using the Loop Explorer
configuration programme to operate in response to alarms or cause and effects as required.
Relay contacts are rated at 30V DC 1 Amp. For full details of 8 way relay boards refer to manual MAN-1074.
16.3 6 way sounder board
The 6 way sounder boards has 6 voltage reversing, monitored sounder outputs which can be programmed to operate as required on
response to alarms or cause and effects.
The sounder boards also have 2 programmable, volt free changeover relay contacts and 2 opto isolated inputs all of which are also
fully programmable via the Loop Explorer configuration programme. For full details of 6 way sounder boards refer to manual MAN-
1075.
16.4 4 way zone board
The 4 way zone board has 4 conventional detection zones, 2 monitored sounder outputs and two programmable volt free, relay
contacts which default to fire and fault actions.
The 4 way zone board is in effect a self contained 4 zone conventional control unit. For full details of 4 way zone boards refer to
manual MAN-1077.
16.5 Syncro View repeater unit
The Syncro View repeater is a very cost effective, full function repeater panel that connects to the remote serial I/O bus and
provides full indication and control of all panels’ status and functions in a compact, slimline enclosure.
Up to 15 View repeaters may be connected to the serial bus as well as any combination of the other types of I/O boards up to a
maximum of 32.
View repeaters have a low standby current consumption
and can be powered by the Aux 24V output of the Syncro
ASM control panel. For full details of Syncro View repeater
units refer to manual MAN-1092.
