DESCRIPTION OF SOFTWARE OPERATION OF THE RADIO SYSTEM
has changed channel, or a data error has occurred, further communication attempts will be made. If these also fail, then the radio detector starts to try to communicate on the remaining channels. This attempt will be completed in 180 seconds. If the radio detector is still unable to communicate the status message with the M400RFE-AS, for example if the M400RFE-AS has lost power, then the communication attempt is terminated. The detector will then retry communications every 180 seconds.
M400RFE-AS INTERFACE MODULE On start-up, the installed software version is indicated by means of a code signal on the green LED on the processor board. All alarm and fault signals received by the interface are latched, and remain on until the M400RFE-AS is reset by the control panel. All faults must be cleared before resetting the M400RFE-AS. Once a fault has been cleared, the new status is transmitted from the detector to the M400RFE-AS; however the fault LED will remain illuminated until reset by the control panel.
Once the M400RFE-AS has returned to normal operation, communications should be automatically re-established with all detectors within 180 seconds. Once a communication has been acknowledged, the detector will return to its normal mode of operation, communicating each 90 seconds.
If a system fault occurs on the M400RFE-AS, both Fault-relays will be simultaneously operated. System fault will be indicated using the 3 M400RFE-AS status LEDS. During Normal operation, the AC LED (mains supply connected or power supplied via the ext. PSU connector) is switched on (Green) and the LEDs, Battery (battery fault) and Tx/Rx Fail (all frequencies are disturbed), are off.
All detectors should have received a confirmation message within 180 seconds, and the system will return to normal operation On entering a Fire Alarm Condition, the radio detector immediately starts to transmit its 'alarm' status to the M400RFEAS. On a radio smoke detector, the LED starts blinking red, whilst on a call point the LED is continuously on. The device attempts to communicate with the M400RFE-AS every 10 seconds. If the alarm signal from the radio device is not acknowledged by the M400RFE-AS within 10 seconds, then the device will try to reestablish communications as described above for M400RFE-AS failure.
The battery supervision can be switched off if selector DIP4 on the daughter board (processor PCB) is switched off. This change must only be made when power to the M400RFE-AS is removed. 2100RFT-AS RADIO SMOKE DETECTOR (and M400DKM-AS and MCPRFE-AS RADIO CALL POINTS) On initial start up, or after a change to the system, a Learn procedure must be carried out as described in Learn Mode. In the learn mode, the red LED on the 2100RFT-AS blinks to indicate that it is sending information to the M400RE-AS. Once this information has been received, the M400RFE-AS will send a signal to terminate the learn mode. On receipt of this signal the 2100RFT-AS led will turn off (both call points operate in the same way, where the 2100RFT-AS is mentioned in this section, the same is true for the call points as well).
If a Fault Condition occurs (tamper activation or detector replaced), the radio detector sends the new condition to the M400RFE-AS immediately. Battery Condition of the detectors and call points is monitored to ensure correct operation of the radio devices. If the battery voltage of the radio device falls below 5.1V, a battery alarm message is transmitted to the M400RFE-AS. This signal gives approximately 60 days warning of battery failure. The device will fail if the battery voltage falls below 4.8V. The battery warning is reset when the voltage at the end of a transmission sequence is above 5.2V. This ensures hysteresis, which prevents oscillation between battery alert and battery OK. For a change in battery fault status, the voltage must be below 5.1V (to enter fault) or above 5.2V (to exit fault) for 10 communications.
In the Normal Condition, the radio detector sends a status communication to the M400RFE-AS every 90 seconds indicating the current status of the detector. Should this status communication not be received by the M400RFE-AS (Interface Fault), for example if the M400RFE-AS

Fit the batteries into the device to be learnt. When the M400RFE-AS detects the signal, it indicates the received field strength on the 8 yellow status LEDs in the panel. A detector will be in the fault condition if the detector is not installed in its base, i.e. indicating a tamper fault. This is not a problem.

Note: The device can optimize the transmission field strength. In order to avoid excessive and unnecessary power consumption from the battery, it is important to have the radio device generate this signal at the exact location it is going to be installed. To add a new detector: • Select a device number for the new device in the M400RFE-AS by using the arrow buttons on the PCB.

CONNECTION OF M400RFE-AS TO THE DETECTION LOOP The M400RFE-AS may be connected to an addressable detection loop using the System Sensor M221E Dual Input Single Output Module. The two supervised input channels monitor the radio interface fire and fault relays to signal alarm and fault conditions to the control panel in two zones, corresponding to detectors 1-16 and 17-32. End of line supervision is via a 47Kohm resistor. The output channel of the M221E is used to command a radio system reset from the control panel. The module address is set by rotary address switches. The address that the M221E is set to relates to the first input (LED A).

The two successive addresses are automatically allocated to the second input (LED B) and the control module (LED C) respectively. When programming the modules during commissioning of the control panel, the following should be noted:
2100RFT-AS RADIO SMOKE DETECTOR OPERATION
The 2 input modules must have short circuit detection switched off and fault delay set to 0 seconds.
Should this status communication not be received by the M400RFE-AS (Interface Fault), for example if the M400RFE-AS has changed channel, or a data error has occurred, further communication attempts will be made. If these also fail, then the radio detector starts to try to communicate on the remaining channels. This attempt will be completed in 100 seconds. If the radio detector is still unable to communicate the status message with the M400RFE-AS, for example if the M400RFE-AS has lost power, then the communication attempt is terminated. The detector will then retry communications every 100 seconds.
In the Normal Condition, the radio detector sends a status communication to the M400RFE-AS every 90 seconds indicating the current status of the detector.
The input module must have short circuit and open circuit detection switched off. The entry in the control matrix for the control module must be for 5 seconds switching during a reset. 2100RFT-AS MOUNTING The 2100RFT-AS is removed from its base by rotating counterclockwise. The base is then fitted directly to the ceiling using 2 x M4 pan head screws (not supplied). If the mounting surface is uneven, care must be taken not to over tighten the screws and distort the ring.
Once the M400RFE-AS has returned to normal operation, communications should be automatically re-established with all detectors within 100 seconds. Once a communication has been acknowledged, the detector will return to its normal mode of operation, communicating each 90 seconds. All detectors should have received a confirmation message within 100 seconds, and the system will return to normal operation
The 2100RFT-AS is then replaced into the base by aligning the arrows on the ring with the lines on the detector cover, pressing home then rotating clockwise until the detector locks in place.
On entering a Fire Alarm Condition, the radio detector immediately starts to transmit its 'alarm' status to the M400RFE-AS. On a radio smoke detector, the LED starts blinking red, whilst on a call point the LED is continuously on. The device attempts to communicate with the M400RFE-AS every 10 seconds. If the alarm signal from the radio device is not acknowledged by the M400RFE-AS within 10 seconds, then the device will try to re-establish communications as described above for M400RFE-AS failure.
Note: Detector batteries must not be installed until the M500RFE-AS System Set-Up stage.

If a Fault Condition occurs (tamper activation or detector replaced), the radio detector sends the new condition to the M400RFE-AS immediately. Battery condition of the detectors and call points is monitored to ensure correct operation of the radio devices. If the battery voltage of the radio device falls below 5.1V, a battery low message is transmitted to the M400RFE-AS. This signal gives approximately 60 days warning of battery failure. The device will fail if the battery voltage falls below 4.8V.

The battery warning is reset when the voltage at the end of a transmission sequence is above 5.2V. This ensures hysteresis, which prevents oscillation between battery alert and battery OK. For a change in battery fault status, the voltage must be below 5.1V (to enter fault) or above 5.2V (to exit fault) for 10 communications. 2100RFT-AS Battery Replacement
Anti-Tamper Function The 2100RFT-AS has an anti tamper device that, when activated, prevents the removal of the detector from its base without the use of a tool.
The 2100RFT-AS uses two 3V CR123A lithium batteries, having a normal life expectancy of eighteen months. To replace the batteries, remove the 2100RFT-AS from its base to allow access to the battery compartment. Ensure that the new batteries are installed with the correct polarity as indicated by the moulding mark next to the battery compartment (See 2100RFT-AS Assembly figure following). The detector will not need to be relearned and address information will be retained during the battery replacement. 2100RFT-AS Testing

Detectors must be tested after installation and following periodic maintenance. However, before testing, notify the proper authorities that the system is undergoing maintenance and the system will be temporarily out of service. Disable the zone or system undergoing maintenance to prevent unwanted alarms. Test the detector as follows: Smoke method:
CAUTION
1. Using generated smoke, or synthetic smoke aerosol from an approved manufacturer such as No Climb Products Ltd, subject the detector to controlled amounts of smoke in accordance with local codes of practice and manufacturer recommendations.
Dust covers are fitted to the detectors to help protect units during shipment and when first installed. They are not intended to provide complete protection against contamination; therefore detectors should be removed before beginning construction, major re-decoration or other dust producing activity. Dust covers must be removed before the system can be made operational.
2. The red led on the detector should latch into alarm within 40 seconds, and the control panel should activate into alarm. 3. Press Reset on the M400RFE-AS to clear alarm.
