ACF – Ancillary Control Function
21.1.1
Outputs
The ACF has a 24V DC monitored output suitable for operating a remote, polarised and suppressed
relay. Monitoring is via an end of line resistor. This output is designated ACF O/P +/-
A clean contact relay rated at 30VDC 1Amp follows the monitored output.
The ACF outputs are activated by a non-silenceable fire signal from the Sigma control panel
section. A red LED indicator is lit when the output is active.
A fault on the ACF outputs is signalled at the Sigma panels as a
General
fault and on the AIM as
ACF
fault.
21.1.2
Configuration:
The ACF can be configured as latching by setting the
LATCH
dipswitch to the On position.
The ACF can be configured as failsafe (Normally Energised) by setting the
FAIL S.
dipswitch
to the ON position.
21.1.3
Controls – only available at Level 2
When the ACF is set to “latching” the
Reset
switch on the AIM module, in order to reset the ACF,
firstly, the Alarm must be reset, and then the ACF can be reset using the Reset switch on the AIM.
When the ACF is set to “non-latching” the ACF output is deactivated when the alarm is reset or
disabled.
