3.3.1 PROGRAMMING
The programming of the output functions is done by setting the “mode” value for the RIM800,
SNM800, and 814I, and by one of the 7 device parameters for the 814H, 814PH, and
814CH. The LPS800 is programmed as an SNM800.
For example the following are the settings for the 814I.
Mode Functional Base Control Remote LED Control
0 Circuit Alarm Circuit Alarm
1 Circuit Alarm Relay
2 Circuit Alarm Point Alarm
4 Relay Circuit Alarm
5 Relay Relay
6 Relay Point Alarm
8 Point Alarm Circuit Alarm
9 Point Alarm Relay
10 Point Alarm Point Alarm
The value must be chosen from the above table to give the desired settings for controlling
the functional base and the remote LED.
For the 814PH and 814CH, programming of the “enhancement multiplier” is included in the
same parameter. The desired enhancement multiplier must be multiplied by 16 and the
result added to the above numbers. The tables in the sections for these detectors (3.9.3 and
3.10.3) include the result when the default enhancement multiplier is used.
For the 814H detector and for an 814PH or 814CH with enhancement disabled, the
“enhancement multiplier” is irrelevant and therefore the above numbers may be entered
directly if desired. The global defaults for parameter 6 for all these detector types should
always include the desired enhancement multiplier * 16.
For the SNM800, other options are also included in the mode. Refer to section 3.22.4 for
details.
3.3.2 OUTPUT STATE UNDER EXCEPTIONAL CIRCUMSTANCES
All outputs retain their state if the MX4428 stops polling the responder (e.g. processing is
stopped), or if the MXP stops polling the devices (e.g. due to a new configuration download
from the MX4428). If a detector is removed from a relay or sounder base, the relay or
sounder output turns off.
If power to the MXP is lost, loop powered sounder bases turn off. RIM800 and SNM800
outputs, relay bases and possibly externally powered sounder bases usually retain their
state until MXP power is restored, then turn off when polling resumes (which may take some
minutes if the MXP has been off for some hours and lost its configuration), then revert to ON
after a few seconds if this is the correct state.
