Description
The 4090-9120 Six Point Module.
Single Address Six Point Module. The 4090-9120 Simplex Six Point Module allows a compatible Simplex fire alarm control panel IDNet communications channel to monitor four T-sense input circuits and control two output relays from a single compact module requiring a single address. Power is supplied by a 24 VDC connection to a listed fire alarm power supply. Multi-Point Device Description. The input circuits and output relay operation are controlled independently and may be disabled separately. Point association is determined at the host panel. At the host panel display, the device address is designated as a single hardware location (such as 1-1).
Supervised Input.
Each of the four input circuits monitors for continuity to an end-of-line resistor and can differentiate between a short circuit contact closure and a current limited contact closure. Four State Operation. Normal is when all contacts are open and there is continuity to the end-of-line resistor; Open is when continuity does not exist to the end-of-line resistor, causing a Trouble condition; Short, indicates that a contact has closed that is directly connected to the input circuit; and Current Limited indicates that a contact has closed beyond a series connected current limiting resistor. This operation allows differentiation between two different contact types due to their wiring location, and reporting as a single IDNet addressable point to the fire alarm control panel.
Six point operation provides four supervised multi-state inputs and two relay outputs in a single package using only one address:
- For use with Simplex® 4007ES, 4010ES, 4100ES, or 4100U Fire Alarm Control Panels providing IDNet communications (4100U requires software revision 11 or higher).
- Typical applications include fan motor control centers, monitoring fire pump motor running status, low pressure fuel warnings, and for multiple dual damper position feedback monitoring.
4090-9120 Input/Output details:
- Four “T-Sense” inputs provide supervised monitoring of normally open, dry contacts.
- Status conditions are Normal, Open Circuit (trouble condition), Current Limited (position input 1), and Short (position input 2).
- Total wiring distance to supervised contacts is up to 500 ft (152 m); for indoor wiring applications.
- Two relay outputs with Form C contacts rated 2 A @ 30 VDC, and 0.5 A @ 120 VAC (resistive ratings).
Compact construction:
- Mounts in standard 4” square electrical box.
- Visible LED flashes to indicate communications.
- Optional covers are available to allow LED to be viewed after installation.
- Screw terminals for wiring connections.
