Description

In the first place,  the Simplex 4090-9051 is an encapsulated package with wire leads. Also, the Simplex 4090-9051 does not provide a status indicating LED.

Individually addressable modules (IAMs) receive both power and communications from a two-wire MAPNET II or IDNet circuit. They provide location-specific addressability to a single initiating device (such as single-station smoke detector alarm contacts or heat detector contacts) or multiple devices at the same location by monitoring normally open dry contacts and the wiring to an end-of-line resistor.

Operation

Contact Closure: In Addition, Closure of the monitored contact(s) initiates an alarm or other response as programmed at the fire alarm control panel. Besides, an open in the monitored circuit wiring will cause a trouble to be reported.

Panel Selections: Selections can be made at the control panel to maintain the alarm condition if the initiating device contacts are momentary, such as from a rate-of-rise heat detector, or to track the device contact status.

• Supervised Class B monitoring of normally open, dry contacts
• Total wiring distance from IAM to supervision resistor(s) of up to 500 ft (152 m)
• Monitored connection is compatible with Simplex® 2081-9044 Overvoltage Protectors for outdoor wiring or electrically noisy applications
