GSA-CR
Control Relay Module
- The Control Relay Module provides a Form C dry relay contact to control external appliances
such as door closers, fans, dampers etc. This device does not provide supervision of the state of the relay contact. Instead, the on-board microprocessor ensures that the relay is in the proper ON/OFF state. Upon command from the loop controller, the relay activates the normally open or normally-closed contact. This module supports only one personality: no user configuration is required.
Overview
The Control Relay Module and the Polarity Reversal Relay Module
are part of the Signature Series system. They are intelligent analog
addressable devices available in either plug-in (UIO) versions, or
standard 1-gang mount versions.
The GSA-CR/MCR Control Relay Module provides a Form
“C” dry relay contact to control external appliances such as
door closers, fans, dampers etc. This device does not provide
supervision of the state of the relay contact. Instead, the on-board
microprocessor ensures that the relay is in the proper ON/OFF
state. Upon command from the loop controller, the GSA-CR/MCR
relay activates the normally open or normally-closed contact.
Standard-mount versions (GSA-CR and GSA-CRR) are installed to standard North American 1-gang electrical boxes, making them ideal for locations where only one module is required. Separate I/O and data loop connections are made to each module.
Standard Features
- Provides one no/nc contact (GSA-CR/MCR)
Form “C” dry relay contact can be used to control external
appliances such as door closers, fans, dampers etc.
- Allows group operation of sounder bases
The GSA-CRR/MCRR reverses the polarity of its 24 Vdc
output, thus activating all Sounder Bases on the data loop.
- Plug-in (UIO) or standard 1-gang mount
UIO versions allow quick installation where multiple modules
are required. The 1-gang mount version is ideal for remote
locations that require a single module.
- Automatic device mapping
Signature modules transmit information to the loop controller
regarding their circuit locations with respect to other Signature
devices on the wire loop.
- Electronic addressing
Programmable addresses are downloaded from the loop
controller, a PC, or the SIGA-PRO Signature Program/Service
Tool; there are no switches or dials to set.
- Intelligent device with microprocessor
All decisions are made at the module to allow lower
communication speed with substantially improved control panel
response time and less sensitivity to line noise and loop wiring
properties; twisted or shielded wire is not required.
- Ground fault detection by address
Detects ground faults right down to the device level.
