GENERAL DESCRIPTION
These plug-in Sensor relay bases are for use with System Sensor 300
Series sensor heads (can also be used with obsolete 1151E/2151E
sensors). They are designed to operate in both 2 and 4-wire systems,
with screw terminals provided for power connections. Normally open and
normally closed relay contacts are provided on a separate terminal block.
The circuit built into the base provides current limiting to the sensor in the
alarm state.
The relay is controlled directly from the sensor, therefore as the sensor
is latched in alarm, so will be the base. For the B324RL and B312RL
latching relay bases, the alarm condition can only be terminated by
removal of the supply to the sensor and base. The B312NL Non-latching
base periodically isolates the sensor from the supply, hence providing an
"automatic reset" once the alarm stimulus has cleared.
SPECIFICATIONS
Base diameter:
Base height:
Weight:
Base fixing centres
Operating temperature range: -20°C to 70°C
Operating humidity range: 0 to 93% Relative Humidity (Non-condensing)
NOTE: In order to prevent possible nuisance alarms due to shock or
vibration, any devices connected to the B312RL base must not signal
an alarm until the relay base contacts have switched for a period greater
than 500mS.
MOUNTING
The sensor base should be mounted using pan head screws, with a
maximum thread diameter of 4mm, and maximum head diameter of
8mm. If required, suitable junction boxes may be used.
Sensor LED Position
If a single LED sensor is used, when mounted in the base the position of
its indicator LED will coincide with terminal 4 on the base.
WIRING
All wiring must be installed in compliance with applicable local codes and
standards, and the authority having jurisdiction.
See figure 2a if the base is to trigger an auxiliary device on a 2-wire
system, or figure 2b for connection to a 4-wire system.
The base terminals are designed to accept cables between 0.5mm² and
2.5mm², however reference should be made to the panel specifications
for acceptable cable resistance and capacitance. The NO/NC terminals
can accept multi core cables up to 1mm² or single core up to 1.5mm²
Note: Do not loop the wire under the terminals - to ensure supervision of
contacts, the wire run must be broken.
To permit continuity testing of the wiring circuit prior to installation of
END OF LINE
the sensor heads, the base contains a shorting spring which acts to
DEVICE
connect terminals 2 (negative in) and 3 (negative out) - see figure 1. To
activate, gently push the spring toward the centre of the sensor until it
clips into place. The short will automatically disengage when the sensor
is installed.
BREAKOUT TAB OPTION (B324RL ONLY)
See figure 1: When power to the B324RL is provided by a power supply
greater than 15V, without current limiting to 25mA or less in alarm, the
tab on the PCB should be broken using a suitable tool such as a pair of
thin nose pliers, otherwise damage may occur to the base and sensor.
Note: If in doubt, refer to the control panel manufacturer. Once broken
the tab cannot be reset!
Tamper Resist Feature
The base includes a feature which, when activated, prevents removal of
the sensor without a tool - see figures 3a and 3b.
