Releasing control using the Simplex
Alarm Control Panel to provide**:
– Coverage for up to 10 hazard areas of Automatic Extinguishing Release and/or Deluge and Preaction Sprinkler System Release
– Releasing Appliance Circuit (RAC) control of compatible Listed/Approved 24 VDC automatic control actuators, one per circuit; or two 12 VDC actuators in series per circuit
– RAC provides short circuit supervision to coil supervision module
– Four, 2 A Notification Appliance Circuits (NACs) in the panel for use with Suppression Release Peripherals (SRP)
– Additional actuator circuit control and additional NACs are available using 4009 IDNet Addressable, NAC Extenders and Suppression Release Peripherals Audible
– Escalation of Events:
- Temporal or 20 bpm March Time pattern for first cross-zone alarm
- 120 bpm March Time pattern to indicate releasing timer active
- On steady to indicate releasing timer expired and actuator is activated
NOTE: Requires NACs dedicated to conventional horn control (not Smart Sync operation) with strobes controlled on separate NACs 4009 IDNet NAC Extenders provide:
– Up to eight NACs for notification requirements and for NAC input to Suppression Release Peripherals
– Control is via IDNet addressable communications 4090-9005/-9006 Suppression Release Peripheral with Dual Command Control:
– Dual command control requires that both IDNet communications commands and an activated NAC are present to initiate the desired release
– NAC provides wiring supervision to the actuator including monitoring of coil continuity Suppression Release Peripheral control features:
– An on-board DC-DC regulator compensates for voltage drops to the peripheral and ensures proper control circuit voltage over a wide operating range
– Provides a single RAC for control of actuators for up to 1 A using a 2 A NAC input Related system components:
– 4010 Series control panel with Releasing Appliqué
– Dedicated NAC output from 4010 or NAC Extender
– Coil supervision module, one per RAC
– Maintenance Switch, one per RAC
– Abort Switch connected via an addressable interface module
