System Sensor M503ME Manuel D'installation

INSTALLATION INSTRUCTIONS FOR M503ME STAND ALONE MICRO
GENERAL DESCRIPTION
M503ME stand alone micro modules provide a two-wire initiating circuit for normally open contact fire
alarm and supervisory devices. The circuit may be monitored for open-circuit and short-circuit wiring
faults. An LED indicator output drive is provided to allow visual monitoring of the module's operating
condition.
The M503ME is small enough to fit inside a single gang junction box behind the device being monitored.
Its size and light weight allows it to be installed without the need to be rigidly mounted (see figure 1)
however it is recommended that the screw fixing positions be used if possible, particularly in larger
enclosures or where the installation is expected to be subject to vibration or movement.

CAUTION
EN54-18: 2005
Do not connect circuit wiring to control unit or modules or apply any power to any portion of the system
until after the circuit test has been performed.
Note: All wiring must conform to applicable local national codes and regulations.
1. Install module wiring in accordance with the design drawings and appropriate wiring diagram
(see figure 2).
2. Set the address on the module per fire system design drawings.
3. Place the module in its desired mounting position.
4. Perform step one to three for all modules.
NOTES:
1. The detection circuit is current limited to 230μA maximum. 24VDC nominal.
2. The detection circuit may help to monitor the following services:
a. Fire: automatic/manual waterflow alarm services with N.O. contact devices
b. Sprinkler supervision with N.O. contact devices.
3. Do not mix services.
