3.19 FP0838 / FP0839 MANUAL CALL POINTS
3.19.1 GENERAL
The FP0838 and FP0839 Manual Call Points consist of a MIM801 mounted on an 1841
Break Glass Switch assembly. They are designed for normally closed contacts as is required
in New Zealand.
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. As faster operation is required in New Zealand,
interrupt operation should be enabled for the MIM801. 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. Default programming of the MIM801 selects open
circuit alarm and interrupt operation.
The FP0838 and FP0839 Call Points include a LED visible from the front. This lights on
alarm and can be programmed to blink when the MIM801 is polled. Operation is otherwise
as for the MIM801.
3.19.2 MX4428 PROGRAMMING OPTIONS - FP0838 / FP0839
These Call Points are programmed as MIM801s. Refer to section 3.16.5.
