Introduction.
The Genesis LGMRU4x4.v2 Masthead Relay Unit is a receiver for Genesis wireless
PIR detectors and provides a simple interface for virtually any kind of alarm input.
Powered from 12 volts DC and weather proof to IP66 it is ideal to be fitted externally
with a dome camera and connected directly into the alarm pre
-
sets.
This product may also be connected to any other kind of alarm system and is very
versatile due to its new improved features such as key fob control and remote arm/
disarm.
Two auxiliary outputs can be used to provide keyfob control of devices such as
electric door release and lighting. Grouped tampers or alarms may also be applied to
these outputs.
Choose between either 4 alarm outputs with corresponding tampers or eight alarm
outputs without tampers. An expansion card is available to increase the number of
alarm outputs to a maximum of 16. (LGREM4x4.v2)
Only PIRs that are between the "lowest PIR index" and "highest PIR index"
are processed, i.e. mapped to one of relays.
All others (that are out of this range) are ignored, filtered
-
out on reception !
Example 1: Unit = 1, Configuration = 1, expansion module is NOT fitted which
means we have 8 relays.
All 8 relays are ALARMs => 8 PIRs are processed then the processed PIRs are
units 1..8
Example 2: Unit = 1, Configuration = 1, expansion module is fitted which means
we have 16 relays, all 16 relays are ALARMs => 16 PIRs are processed; then the
processed PIRs are units 1..16
Example 3: Unit = 1, Configuration = 2, expansion module is NOT fitted which
means we have 8 relays, 4 pairs of ALARM+TAMPER => 4 PIRs are processed;
then the processed PIRs are units 1..4
Example 4: Unit = 1, Configuration = 2, expansion module is fitted which means we
have 16 relays, 8 pairs of ALARM+TAMPER => 8 PIRs are processed; then the
processed PIRs are units 1..8
Example 5: Unit = 20, Configuration = 1, expansion module is NOT fitted which
means we have 8 relays, all 8 relays are ALARMs => 8 PIRs are processed;
then the processed PIRs are units 20..27
Example 6: Unit = 62, Configuration = 2, expansion module is fitted which means
we have 16 relays, 8 pairs of ALARM+TAMPER => 8 PIRs are processed;
then the processed PIRs are units 62..64 (maximum index)
=> processed PIRs are units 62..64
(only 3 pairs A+T will operate, all other relays remain Idle)
Note 2: If Function_1 is Global_Alarm or Global_Tamper, then parameters S1,E1
specify the Start and End PIR index that are included.
If Function_2 is Global_Alarm or Global_Tamper, then parameters S2,E2 specify
the Start and End PIR index that are included.
Start and End indexes must be set correctly.
If not, then Receiver makes some automatic corrections:
If Start is lower then the index of the lowest mapped PIR then the lowest mapped
PIR index is used as Start instead.
If End is higher then the index of the highest mapped PIR then the highest mapped
PIR index is used as End instead.
If End is lower than Start, then group consists of only 1 PIR, the one with index
start.
