3.16 MIM800 AND MIM801 MINI INPUT MODULES

3.16.1GENERAL

The MIM800 and MIM801 Mini Input Modules are suitable for interfacing voltage free contacts such as switches, relay contacts, flow switches, or non-indicating detectors.

Dedicated Manual Call Point products are available that have the MIM800 or MIM801 mounted on the back of an MCP. Refer to sections 3.18 and 3.19.

Both the MIM800 and MIM801 may be used in normally open or normally closed configurations, and the normally open configuration may or may not include short circuit fault monitoring. Refer to Figure 3.4 for wiring topology.

The normal response time to an input change of state is 0 – 5 seconds, as each device is polled at 5 second intervals by the MXP. If faster operation is required, interrupt operation can be enabled. Interrupt operation allows a change to be signalled by the device so that the MXP detects the change immediately, rather than waiting for the next poll of the device.

To interrupt on closing contacts, the MIM800 is required. To interrupt on opening contacts, the MIM801 is required. An interrupt can be generated on only the transition from normal to alarm, transitions from alarm to normal will always require up to 5 seconds to be recognised.

Fault supervision is provided by a 200Ω EOL resistor - open circuit fault in a normally open configuration and short circuit fault in a normally closed configuration. In addition the normally open configuration can be programmed to also generate fault on short circuit. In this case only one alarm contact is allowed, a 100Ω resistor must be wired in series with the alarm contacts, and the fault threshold must be specially programmed. (Set Parameter 2 to 176 for a MIM800 and parameter 5 to 40 for a MIM801).

The input wiring should be limited to less than 10m in length and located well away from all electrical noise sources.

Recognition of a fault condition takes about 30 seconds.

The MIM800 and MIM801 have screw terminals for an Alarm Indicator LED. No series resistor is required. A current of about 2.5mA will be supplied when the LED is on.
