Simplex 4090-9121 Security Monitor

Simplex 4090-9121 Security Monitor has both power and communications supplied by a two-wire 4100ES, 4100U or 4010ES IDNet circuit. It provides location-specific addressability for up to five initiating devices (such as window or door magnet switch contacts or other similar security devices) by monitoring the circuit wiring connections to either normally closed or normally open dry contacts (one type per IAM). Operation.

The Simplex 4090-9121 Security Monitor circuit is “arm” by selection from the fire alarm control panel, such as during nonworking hours, monitor loop activity causes a priority 2 alarm at the panel. When the circuit is “disarm”, such as during normal working hours, normal and abnormal conditions would be tracked as events.

Depends on the point type select, an open or short in the monitor circuit wiring will cause trouble to be a report or a short can be track as an event.

Addressable communications supply both data and power over a single wire pair to provide:

• Supervised Class B monitoring of normally closed or normally open dry contact security devices.
• Monitored conditions are Open, Normal, Abnormal, and Short
• Abnormal occurs with ±50% of monitor loop current change
• Total wiring distance from Security IAM to supervised contacts up to 500 ft (152 m)
