External relay module
The relay module is available in two versions: CPS RM4 (with 4 relays) and CPS RM8 (with 8 relays).
It also has two logic inputs (LI) which can be activated.
In maximum configuration, the CPS can manage 256 relays (ex: 32 modules with 8 relays each). For
more information about the logic inputs: see: Logic inputs module.
The relays are individually programmable. The operation of each relay depends on its configuration
and its function.
Each of the 6 sensor alarms [AL1 - AL2 - AL3 - AL4 - Out of Range - Fault] can control one or more of
the 256 relays. Several events can be linked to one relay.
In case of a
module relay fault, all relays of this module are restarted.
The CPS central controller will change the relay status unless they belong to a different module type.
Restarting will resolve the problem.
Relay status lights
Each relay has a red LED to indicate its status

. Flip the switch to ON (positive security) or OFF (negative security) as
desired. Each switch acts on its corresponding relay (switch 1

relay RL1, switch 2

relay RL2, etc.).
(Fig. 11).
Note: Only switches 1-4 are active in the CPSRM4 module.
