ABB SACO16D1 Alarm Display Application Guide

The flashing signal mode can be selected through programming, for example:

FCFR: On site contacts follow flashing lights.

AACR: Confirm action control flash.

ISR: Pulse shaping flash (fixed 300ms pulse).

2.5 Channel Interlocking Function

Each alarm channel is equipped with three interlocking inputs (types 1-3) and one interlocking output (type 0), achieving complex logical interlocking through eight internal interlocking lines:

Type 1: Only block the Class A flashing signal of this channel.

Type 2/3: Block the entire passage. The difference is that after the interlock is released, the channels return as "confirmed alarm" or "new alarm" respectively.

Type 0: Output interlocking signal when channel is activated, which can trigger interlocking input of other channels.

This feature allows the construction of up to eight levels of interlocking logic, suitable for complex alarm scenarios with priority or mutual exclusion relationships.

2.6 Comprehensive self-monitoring system

The equipment has a complete self-monitoring function and continuously monitors:

Internal logic voltage (5 V, ± 12 V).

48V DC on-site contact voltage.

Microprocessor program execution (watchdog).

Serial communication link status.

Once a fault is detected, the 'FAULT' LED lights up and the self-monitoring relay (normally charged) loses power and releases. Fault information (such as parameter memory errors, on-site contact voltage undervoltage, etc.) can be displayed on the screen and transmitted through the SPA bus. The system also has a "pumping" monitoring function, which can set the maximum number of alarms allowed per minute to prevent event register blockage caused by contact jitter.

3、 Installation, wiring, and startup

3.1 Mechanical Installation

The device is designed for embedded installation and secured with two mounting brackets. To accommodate different panel thicknesses, a lifting frame (SPA-ZX 101/102/103) of 40mm, 80mm, or 120mm can be selected. During installation, ensure that the panel opening size is accurate and tighten the fixing screws to ensure IP 54 protection level.

3.2 Electrical Wiring

All wiring terminals are located on the back of the chassis:

Auxiliary power supply (terminals 20-24): Note that the voltage range should match the selected power module. If dual power supply is used, the two power sources must be electrically isolated (such as using isolation transformers).

Protective grounding (terminal 22): must be reliably connected.

On site contact input (terminals 49-72): Connect passive dry contacts.

External confirmation/reset (terminals 16-18): Remote buttons can be connected.

Flash output relay (terminals 5-12).

Serial interface (terminals 1-3, 13-14): using RS-485 standard, supporting SPA bus protocol.

Important reminder: Before wiring, be sure to confirm the power supply voltage specifications; Ensure that the protective grounding is firm; If dual power sources are used, their networks must be electrically isolated.

3.3 Power on and Operation Testing

After power on, all active alarm channels will display as "confirmed" status. The device provides convenient operation testing:

Long press the "Confirm/Reset/Test" button on the front panel for about 1 second: all LEDs (except for FAULT) light up, and the display shows "8888" for visual testing.

Long press for more than 15 seconds: triggers self-monitoring relay action, FAULT LED lights up.

The on-site contact circuit and external audio equipment need to undergo separate functional testing.

3.4 Nameplate Labels

The equipment comes with drawing film for making channel nameplates. Users can use a stylus or typewriter to fill in channel description text in a 20mm x 20mm square, and then insert the film into the slot on the left side of the front panel. Note that the starting position of the text should be slightly to the left to avoid blocking the channel LED indicator light.

4、 Programming and Parameter Configuration

The core advantage of SACO16D1 lies in its high on-site programmability. All parameters are stored in non-volatile EEPROM and can be set through the five buttons on the front panel or via a serial interface (using PC software such as SMS 010). The selector plug (S1/S2 position) on the front panel PCB can be used to prohibit unauthorized programming.

4.1 Programming buttons and interface

Channel selection key (∩): Cycle through channels 1-16.

Parameter selection key (↓): Switch between five parameter groups (INPUT, GROUP, OUTPUT, INTERLOCK, MODULE).

Cursor control key (→): Move the cursor (flashing position) between the numbers on the four digit display.

Data value selection key (↑): Change the value of the current cursor position.

Enter command key (Reset): Store the currently displayed parameter values in memory.

4.2 Main parameter configuration steps

Channel related parameters (INPUT group):

S1: Input delay, S2: Reset delay.

S3: On site contact type (0-7, as mentioned earlier).

S4: Channel designation indication (0=standard sequence; 1=standard sequence+return time sound; 2=only touch point following indication without sound).

S11: Jitter monitoring (00=disabled; 01-99=allowed number of events per minute).
