AC219 Annunciator Controller For use with CM800 and DS100 Annunciators

Installation Manual

The Alpha Communications® AC219 Annunciator Controller is designed to be used in conjunction with a CM800

Emergency Call system, or a DS100 Door Sentry system. When a switch device gives a contact closure or opening, depending on configuration, this unit will cause the attached annunciator and/or other devices to sound and to illuminate

the appropriate visual indication.

INSTALLATION PROCEDURE

The AC219 must be placed in a cool, clean and dry location. All connections must be clean and secure to insure reliable

operation. Some installations or local codes may require that it be installed in a protective junction box with its transformer and the transformer’s primary 120VAC connections.

WIRING REQUIREMENTS

The AC219 Annunciator Controller must be powered by a 16VAC 30VA transformer located within 100 feet (30 meters)

using #18AWG wiring. The transformer must be mounted in accordance with all applicable codes. Please note that the AC219 rectifies and regulates the 16VAC input into 24VDC power for system operation.

Since wiring will vary, depending on the specific system in which it will be used, please refer to the suitable wiring

diagram(s) in this manual as well as system specific information found in the appropriate system manual.

When servicing any system of this type, always check all wiring for shorts and grounds before applying system power to

prevent potential damage to the wiring and system components. Do not service the system while power is applied.

CM800 System Description The CM800 system is designed as a single priority level emergency call system. With the AC219 Annunciator Controller, mechanically latching devices of various sorts can be used to send an alert to a master station or multiple master stations

connected in parallel. The CM800 system can support corridor lights and can trigger floor bells, strobes, and many other audible and/or visual annunciators. All call resets must be done at the originating station.

DS100 System Description The DS100 system is designed to alarm when a door, window, or cabinet switch triggers a change of state in a normally open (NO) or normally closed (NC) momentary contact device connected to the system. The latching of the alert is done

in the circuitry of the master station and must be reset there. Usually DS100 systems have one master station but additional masters may be used, however the alarm must be reset at all masters when this is done.

AC219 OPERATION THEORY The AC219 consists of several separate sections performing specific functions:

Power Supply The AC219 is powered by the 16VAC transformer input at terminals T1 & T2 and rectifies and regulates the voltage to a

controlled 24VDC output at P (positive) and N (negative). The system uses this voltage to power the dome lights on a

CM800 system, generate the tone, and illuminate the Annunciator bulbs when the devices complete the circuit.

Tone Generator A built in oscillator sends a tone to the speakers in all master(s) and duty station(s), when an alarm is active. The tone

can be silenced at a master by pressing the Tone off button. The Tone indicator light will also turn off to indicate that the master has been silenced. This will also silence all Duty Stations related to this master. The tone will be silenced until all

calls have been reset at which point the tone will automatically turn back on. Tone volume is variable by turning the volume control potentiometer on the AC219 but can not be completely silenced.

Alarm Sensor A built in detector circuit monitors current flow in the system. When the devices are all in their off state, there is no current flow. The D (detector) terminal is where the Annunciator lights get their positive side power. Their negative side

is provided through the call device (pull station, push button, or door sensor) to complete the circuit.

As soon as a device switch closes and allows the current flow to light the Annunciator bulb, the detector circuit starts the alarm tone. The alarm will continue until all devices are back to their off state.

Auxiliary Relay The AC219 also provides a Form C relay that will change state during an event, enabling additional specialized equipment to be activated such as floor bells, sirens, strobes, auto dialers, or other means of notification.
