is reset. If JL is ON, the unit will follow the FIRE/ACP TRIGGER. Install PWX2K2 2.2K (EOLR) resistor at the Key Switch or Push Button to execute
this operation.
4. Relay Output
a) DC Fail: If one or more of the eight outputs fail due to overcurrent or short circuit, the DC Fail Relay will open. Connect this output to a monitoring
device. (28V DC, 300mA)
b) Status Output: The dry contact Relay Form "C" will change state (de-energize) when the FACP or ACP input activates. Connect this output to a
monitoring device. (28V DC, 300mA)
5. Cascade Connection
To seamlessly integrate multiple ACM8ECB units, begin by connecting the 'Status Output' relay C and NC terminals from the first unit directly to the
'REMOTE RESET/REX INPUT' of the subsequent unit — a procedure unaffected by polarity. Subsequently, it's crucial to remove the JR from the first
unit and fix an EOLR (2K2) onto the 'Fire Trigger' terminal of the second unit. If the integration extends to a third unit or beyond, ensure the removal
of the JR from the preceding unit for each additional setup. For a visual aid of these configurations, refer to Fig.1. For those employing the Latch
Mode, it's vital to note that only the JL jumper from the primary unit needs removal. In such a setup, the first unit remains the epicenter for initiating
all engineering reset operations.
6. ACM4ECB LED Indication
The Red LEDs (L1 to L4) indicate DC presence (when ON) and that the Output relays are energized. When OFF, the LEDs indicate that the Relay is
de-energized and the output is OFF. Yellow LEDs (LD1 to LD4) signal overload or short on the output, with the output current limit set at 2.5Amp
(rated at max 2.0Amp). The Green LED (L9) is normally OFF, but switches ON when an alarm is received from FACP/ACP, staying ON as long as the
FACP/ACP input status remains unchanged. If JL was removed, this LED stays ON until a manual RESET circuit reset.
7. Access Control Panel (ACP) Trigger input
The controller offers four inputs split between CN10 and CN11, each with two IN and two GND terminals. Activate these inputs by shorting the IN
and GND terminals of the respective inputs.
8. FACP/ACP Input Programming
If you want the output relay activation to follow the FACP or ACP input, set the DIP switch corresponding to the desired relay to the "OFF" position. In
the "ON" position, the corresponding output relay will not be affected by FACP, ACP, or Rev. Pol input.
9. Isolated Output Configuration
If any of the outputs require an isolated DRY CONTACT configuration, remove the respective Jumper (J1 through J4). This provides Form "C" (C NO
NC) connections to connectors CN1 through CN4, isolating them from the internal power source. The Relay Rating is 28V DC, 2A.
11. CONNECTION
Jumper
JL OFF & U1 JP OFF
JL ON & U1 LP ON
JL OFF & U1 JP ON
JL ON & U1 JP OFF
There are two jumpers (JL & U1 JP) that set the configuration for how the output power functions when the fire input is triggered then restored or when
the AC MAINS is dropped and then restored.
Note: Jumper U1 JP when used will be placed over the middle and left pins. When not in use will just be covering the right-most pin as a place holder.
Jumper JL ON or OFF will control if the output will be restored automatically or manually when the fire input has been triggered (closed) then opened.
Jumper U1 JP will control if the output will be restored automatically or manually when the Mains power has been dropped and restored.
See the table above for what your application requires.
