The AUTOCALL contact monitor modules IXA-
500CMA (Style B & D)and IXA-501CM (mini
module) provide an initiating zone suitable for
contact devices such as pull stations, waterflow
switches and sprinkler supervisory devices. Each
module reports and input from any contact device
in its zone as a single address to the AUTOCALL
TFX series systems.
Each contact monitor module uses one of 126
available addresses on an AUTOCALL TFX
signalling circuit. It responds to regular polls from
the control panel and reports its type and the
status of its initiating circuit. The LED latches
steady on alarm.
These modules may be programmed to report
inputs as either alarm or supervisory conditions.
Another programming option invokes a special
polling interrupt routing, resulting in quicker alarm
response than systems which rely on simple
polling techniques to detect an alarm.
IXA-500CMA
The IXA-500CMA provides a Style B or D initiating
circuit and mounts on a standard 2-gang electrical
box. An attractive plastic cover with eggshell finish
is included. An LED is visible through an opening
in the plastic cover and illuminates steadily during
alarm.
The IXA-500CMA may be programmed to monitor
normally open or normally closed contact devices.
IXA-501CM
The IXA-501CM mini module provides a Style B
initiating circuit. Its compact size makes it ideal for
placement inside a standard electrical box behind
the monitored contact device, such as a
pullstation.
Features
. Supervises and monitors dry contact devices
. Normally open and normally closed
programmable options (IXA-500CMA)
. IXA-501CM Fits inside standard electrical box
. IXA-500CMA Mounts on standard 2 gang
electrical box
. High EMF/RFI noise immunity
. Powered directly by signalling circuit (no
additional power required)
. Programmable for normal or fast (polling
interrupt) alarm reporting

The AUTOCALL CAA-500LI module is used only
with the AUTOCALL TFX fire control panels to
detect and isolate short circuits. This module
should be installed between groups of
addressable devices to prevent failure of the entire
signalling circuit loop in the event of a short
circuit. Upon detection of a short circuit, this
module opens up the positive leg of the signalling
circuit. On a Style 6 circuit, this causes a shorted
section between two CAA-500LI modules to be
isolated from the rest of the loop. The AUTOCALL
TFX panel indicates which devices in the loop
have been isolated, to assist in locating and
correcting the short circuit condition. Once the
short circuit has been cleared, the CAA-500LI
automatically resets, and communication with the
isolated devices is restored.
Features
. Isolates short circuits on signalling circuit to
prevent failure of entire circuit
. Automatically resets on correction of short
circuit
. Status LED indicates short circuit detection
. No external power required
. High EMF/RFI noise immunity
. May be configured to meet NFPA style 7
requirements

AUTOCALL CAA-500LI Module
The AUTOCALL Addressable detector monitor
module IXA-500DMA, provides an initiating zone
suitable for compatible two wire smoke and heat
detectors. Each module reports an input from any
detector in its initiating circuit as a single address
to the AUTOCALL TFX series system. Up to 20
detectors can be connected to the initiating
circuit, depending on the specific detectors used.
Each detector monitor module uses one of 126
available addresses on an AUTOCALL TFX
signalling circuit. It responds to regular polls from
the control panel and reports its type and the state
of its initiating circuit. This module contains bi-
coloured LEDs (red for alarm and yellow for fault).
Features
. Supervises and monitors two wire smoke and
heat detectors
. Supervises 24Vd.c. detector power on two wire
loop
. Resets detectors on command from control
panel
. Style B and D initiating circuits
. Contains Bi-coloured LEDs to display alarm/
fault status
. High EMF/RFI noise immunity
